by Kiko Ramos | Dec 27, 2024 | Equipment analysis

The arc in C is specialized medical equipment used in radiology and interventional procedures to obtain real-time X-ray images of the inside of the human body. It is a mobile device that enables radiological and fluoroscopic imaging. Its name derives from its C-shaped structure"which allows a wide range of movements and the acquisition of images from multiple angles and positions for capture specific anatomical views without moving the patient.

It is used to obtain X-ray and fluoroscopic images without having to move the patient to the radiology department. Therefore, diagnostics and procedures can be performed at the patient's hospital bedside or on the operating table during surgery. Its use is essential in areas such as surgery, orthopedics, traumatology, cardiology, neurology, urology and minimally invasive procedures.

Among the main advantages offered by the arc in Cis that facilitates diagnosisoffers a high precision and safety, y decreases the duration of surgical interventions in which the patient is under general anesthesia. In the following article, we analyze how a C-arm works, its parts, functions and main applications and uses. medical equipment.

How does a C-arc work?

The operation of a surgical C-arm is similar to that of the X-ray machines conventional. Combine two main elements that work in an integrated manner How does this process work?

X-ray generator

The process begins with the X-ray tubelocated at one end of the "C" arm. This component emits a beam of radiation which passes through the patient's body. Collimators, which are adjustable devices on the tube, delimit the radiation field, ensuring that only the area of interest is irradiated. This not only improves image quality, but also minimizes radiation exposure to other areas.

When the X-ray beam passes through the patient's body, interacts with the different tissuesgenerating a phenomenon called differential absorption. The Denser tissues, such as bones, absorb more radiation. and are represented as white areas in the image. On the other hand, the soft tissues and air-filled areas allow the rays to pass through more easily, appearing in gray or black tones. This difference in absorption is what creates the contrast in radiological images.

Image detector or intensifier

At the opposite end of the X-ray tube is the image detector or intensifier. This component receives the rays that have passed through the patient and converts them into electrical signals. Modern detectors, called digital flat panel detectors, process these signals to generate high-resolution images. This advance has largely replaced traditional intensifiers, offering greater sharpness and less radiation exposure.

The signals captured by the detector are sent to a processing system that converts the data into digital images.. This software automatically optimizes parameters such as contrast, brightness and sharpness to ensure that images are clear and easy to interpret. These images are displayed in real time on monitors connected to the system, allowing the medical team to observe the area of interest while the procedure is being performed.

PACS system in radiology: What is it and how does it work?

by Luis Daniel Fernádez | Dec 13, 2024 | Equipment analysis

The technology has had a significant impact on the healthcare system, especially in the radiology area. In recent years, one of the most relevant changes following the advent of the Internet has been the use of computerized systems in the field of image diagnosis. This has allowed the development of a digital imaging department where medical information can be managed and stored conveniently and securely.

In a digital imaging department, we can distinguish three fundamental tools: the PACS system, the RIS system and the HIS system. In the following article, we analyze what the PACS system is, how it works and its relationship with the RIS and HIS system.

What is the PACS system in radiology?

The term PACS stands for Picture Archiving and Communication System, which refers to Image Archiving and Communication System. This is a computer software used in the radiology area for the following purposes store, manage, present and share medical images and diagnostic procedure reports electronically.

Before the advent of the PACS system in radiology, the images generated after diagnostic examinations were stored in a physical format, mainly as radiographic films. Therefore, from the time the medical test was performed, there was a long process until the final image was obtained. With digitization, it is now possible to resort to a AI software for the different medical teams to obtain an accurate faster and more efficient access to informationwhich will allow optimize workflow in clinical practice.

How does the PACS system work?

A PACS system consists of a series of mechanical and electronic components which are connected to each other by a copper or fiber optic communication network. Specifically, we can differentiate between four main components:

1. Image acquisition hardware
2. Workstations for image interpretation and review
3. Servers for storage and transmission of images
4. Network for data transmission

All these elements work in an integrated manner to allow medical images to be captured, stored, distributed and displayed digitally. Through the use of this network, the graphic information generated in different studies, such as a CT scan, is transmitted to the magnetic resonance imaging o TAC.

How does this process unfold?

First of all, data from the system servers is passed to the archiving drives. Subsequently, they are distributed to the stations where radiological physicians review the generated medical images and also to the teleradiology serverswhich allow access to the archive through the Internet.

With a digital radiology PACS system, you can view images remotely from any medical department, office or externally. To do so, health care personnel have special identification codes which allows them to access diagnostic tests for each patient.

The DICOM medical imaging communication standard

For information and images to flow through the PACS system components, it is necessary to comply with the DICOM medical image communication standard. DICOM stands for Digital Imaging and Communications in Medicine and is a standard for the communication of medical images. standard for digital storage and transmission of medical images and related patient information.

It is responsible for define the file format and structure and, in turn, includes a communications protocol to facilitate connectivity between medical devices and systems. However, it should be noted that the majority of modern devices and medical equipment current DICOM images are produced.

Advantages of using a PACS system in radiology

We analyze the main advantages offered by a PACS system in the management of radiological images:

Improved workflow in radiology departments

Radiologists and medical teams involved in the diagnostic imaging process can access and review digital images from any workstation on the hospital's network or remotely through the web server. This allows rapid consultation of studies and collaboration between physicians and specialists.

Error reduction

As the format of medical images is no longer physical, eliminating the possibility of duplicate diagnoses and also reduces both the risk of loss as the damage of the generated medical images.

Integration with other IT systems

One of the main advantages of the PACS system is that it allows the integration with other IT systems that can be used in health careThe RIS (Radiological Information System) and HIS (Hospital Management Software).

Capacity to store large volumes of data

Not only is it essential for clinical management and patient care, being able to store large volumes of medical imaging data is a key aspect for research and education in the area of health and medicine. In this way, researchers can access image databases for studies and students in training can use many of the images as educational material.

More accurate and detailed diagnosis

The use of the PACS system provides a more detailed reading of the diagnoses. This is mainly because the images are reviewed on high-resolution monitors and can be manipulated more accurately, which helps to detect abnormalities present in the image more quickly and accurately. 

Saving time and resources

Another of its advantages is that it offers a time saving and a decrease in the workload of the staff.The cost of printing X-rays and other radiological elements was also reduced. At the same time, waiting times and resources at the hospital level are reduced.

Relationship between the PACS, RIS and HIS system

PACS, RIS and HIS are three systems key components in the digital health informatics ecosystem. Their interrelation is essential for the efficient functioning of the healthcare services of any clinic, health center or hospital. While the PACS system in radiology is used to manage, store and share images of the different diagnostic imaging procedures, the RIS and HIS system have other functions. What is each used for and what is the relationship between them?

The RIS system

The RIS system or Radiology Information System, is the program that runs the digital radiology department. It is a software that contains all the information of the radiology area and hospitals, thus enabling manage information and processes related to diagnostic imaging services.

Functions performed

• Scheduling of appointments and studies
• Order generation
• Recording of results with the generated medical images
• Workflow management in the radiology department

The HIS system

As for the Hospital Information System (HIS), it is a system of hospital information system. By using it, all the data are stored in the data related to the management and administration of a hospital. It is designed to manage all areas involved in the operation of a hospital from a single platform.

Functions performed

• Management and scheduling of medical appointments
• Patient care: Administration of patients' medical records and results of medical examinations performed.
• Human Resources
• Billing
• Monitoring the quality of medical care

Interaction of PACS, RIS and HIS systems

• HISThe central system that coordinates and stores all patient information in a clinic or hospital facility, including demographic, clinical and financial data.
• RISIt communicates with the HIS system to obtain relevant patient information and to manage the radiology area. It is used to schedule radiological procedures requested from other areas of the hospital.
• PACSRIS-PAC: Works hand in hand with RIS to store and manage the medical images generated by the requested studies. The RIS-PAC interaction allows the report to be presented in both systems so that each report appears linked to the images of the study performed.

In conclusion, a PACS system is a fundamental tool in the radiology area to be able to store and manage medical images digitally. All this helps to improve healthcare and promote faster, more detailed and accurate clinical diagnosis.

The X-rays are a form of electromagnetic radiation, similar to visible light. This medical technique was created in 1895 by the physicist Wilhem Conrad Röntgen, whose findings led to the development of radiological practice. It is an essential method in the medical field and is used by means of specific equipment: the X-ray machines. X-rays are able to penetrate matter, so they can pass through most objects and tissues, including the human body. Once through the body, the X-rays reach a radiographic plate or computer where digital images, known as radiographs, are generated.

The radiographs are a type of diagnostic imaging and are used to analyze the different internal areas of the organism. The images that are produced are displayed in different shades of black and white.since each tissue allows a certain amount of X-ray beams to pass through it.. Dense materials, such as bones and metals, appear black, while muscles and fatty elements appear in shades of gray. In some types of X-rays, a contrast medium, such as iodine or barium, is introduced so that tissues can be visualized in the images in greater detail.

X-rays can be used aloneas in the equipment of conventional radiology, or combined with other techniquessuch as computed tomography or CT. In the following article, we explain how X-rays work, what they are used for and the types of X-ray machines that exist.

How do X-ray machines and X-rays work?

For imaging in conventional radiography, the patient stands behind a screen that blocks the radiation and operates the X-ray equipment. During the procedure, the body part to be analyzed is placed between the X-ray source and an X-ray detector.

The X-rays passing through the tissues are recorded on a radiation detector plate. Y, depending on the density of the tissues, will pass through a certain amount of radiation.The image produced shows the different degrees of density of the internal structures of the organism. The higher the tissue density, the more X-rays pass through and the whiter the image generated.How are the different tissues displayed?

• Metal has a white color.
• Bone see almost white.
• Fat, muscle and fluids are shown with shadows, in different shades of gray.
• Air and gas are displayed in black color.

Main uses of X-rays

X-rays have multiple uses in the field of medicine. X-rays are used for the diagnosis of diseases and injuries, as a support technique to perform surgical procedures, as a therapeutic treatment, in minimally invasive procedures and for the early detection of diseases. Below, we discuss the different procedures where X-ray technology is used to diagnose and treat diseases:

Diagnostic radiography

X-rays are used as diagnostic test to detect bone fractures, tumors and abnormal masses, pneumonia, etc.as well as lesions, calcifications, foreign objects, intestinal obstructions and dental problems.

2. CT or computed tomography

It combines the X-ray technique together with the computed tomography or CAT scan to create cross-sectional images of the body. Subsequently, can be combined to generate a three dimensional image X-ray images. CT images are more detailed than those of a conventional X-ray and allow professionals to analyze the internal structures of the body from various angles.

Mammography

Breast radiography is used to detecting breast disorders, mainly breast cancer. Breast tissue is sensitive to radiation, so special mammography units are used to minimize radiation exposure. digital radiology equipment.

4. Fluoroscopy

X-rays and a fluorescent screen are used together. to obtain real-time images of the movement inside the body. It is also used to analyze diagnostic processes, such as following the path of a contrast agent.

One of the uses of fluoroscopy is to analyze heart movement and beats. For this, radiographic contrast agents are used to view the blood flow in the heart muscle, blood vessels and organs. This type of technique is also used to guiding an internally threaded catheter during cardiac angioplastya minimally invasive procedure to open clogged arteries that supply blood to the heart.

5. Therapeutic use of radiotherapy for the treatment of cancer.

Another use of X-rays is as therapeutic technique to destroy tumors and cancer cells. The dose of radiation used to treat cancer is higher than the radiation used in diagnostic tests. This type of therapeutic radiation can come from X-ray equipment or radioactive material. that is placed in the body or bloodstream.

Types of X-ray machines

What types of X-ray machines are available on the market? We can differentiate the following medical equipment using this technology:

Conventional X-ray machines

They are the most basic equipment and are designed to obtain static images of the internal structures of the body. It is used for diagnose bone fractures, pulmonary evaluation by means of a chest X-ray and the identification of dental problems.

Portable X-ray machines

This type of X-ray machines are lightweight, compact and portableThe products can be easily transported. Used in emergencies and rural areasand to care for patients who cannot be transferred.

Digital X-ray machines

They are replacing film plates with digital detectors to develop a real-time diagnostics and the generated images have a high resolution and are of higher quality.

Fluoroscopy systems

These are specific devices that use X-ray technology for the following purposes observing dynamic processes in the body in real time. These machines are used for minimally invasive surgical procedures, gastrointestinal studies and orthopedic diagnostics.

Mammography machines

They are designed for perform breast tissue studies. They are essential for the screening for tumors, abnormalities and breast cancer. In this case, the X-ray emission is low energy in order to better analyze the soft tissues that make up the breasts.

Computed tomography or CT equipment

These units are designed with a advanced system that uses X-rays to create detailed, three-dimensional images of the body. It is highly accurate and is used to evaluate internal injuries, tumors, as well as brain, thoracic, abdominal and extremity studies.

C-arc

These X-ray machines are equipped with a C-shaped arm que emits the X-rays from one end and captures digital images at the other end. C-arc is used for image-guided surgical procedures and in orthopedic and cardiovascular interventions. It offers a deeper analysis, since the area to be analyzed can be visualized from different angles.

Dental X-ray machines

This type of device is designed for capture images of the teeth and various maxillofacial structures. On the one hand, there are the intraoral equipment which capture images of the inside of the mouth and, on the other hand, there are the extraoral equipment which include panoramic systems that take full images of the jaw and mouth. They are mainly used for the diagnosis of caries, periodontal diseases and orthodontic planning.

X-ray machines for bone densitometry

X-rays are used to measuring bone mineral densityand, therefore used to diagnose osteoporosis and perform the follow-up of bone loss treatment.

Conclusion

In conclusion, X-rays are a very complete technique that has a large number of uses in the health field and, depending on each medical need, there is specific X-ray equipment to analyze, study and treat various diseases.

What is a CT scan and what is it used for?

by 4D Medical | Nov 14, 2024 | Equipment analysis

The computed tomographyalso known as computed axial tomography, also known as computed tomography, or TAChas become one of the most popular techniques of image diagnosis most commonly used. It is a procedure that uses special X-ray equipment and advanced computers to obtain three-dimensional images with different slices of the body.

Since its clinical introduction in 1971, it has undergone successive advances that have allowed its application in different fields of medicine. At present, computed tomography is used to diagnose disorders such as cancer, cardiovascular conditions, infectious processes, trauma and diseases of the locomotor apparatus. In the following article, we analyze how it works, what it is used for and the origin and evolution of this diagnostic test.

How does a CAT scan work?

In order to perform this diagnostic imaging, the following is used computed axial tomography system which incorporates a X-ray scanners generating three-dimensional images with different cuts of the interior of the organism.

These slices are called tomographic images and are used for the following purposes study various internal regions of the bodyThe CT scanner can be used to view everything from organs, bones and soft tissues to blood vessels. In contrast to radiography, which only provides a two-dimensional representation, the CT scan makes it possible to observe the three-dimensional images. This makes it possible to analyze tissues with greater detail and clarity. Another aspect to note is that the CT scanner utilizes a X-ray source and has a ionizing radiation higher than that of an X-ray.

During the procedure, the CT scanner rotates around the circular opening of a threaded structure called Gantry. The patient lies on a bed and is inserted inside the scanner so that the specialist can analyze the tissues. The X-ray detectors are located in front of the X-ray source and generate a series of images through different cuts. Subsequently, are transmitted to a computer where the interior of the organism can be visualized and analyzed.

CT contrast medium

As with X-rays, dense structures within the body, such as bones, are easy to image. However, soft tissues are more difficult to image. For this reason, contrast media have been developed that increase the visibility of tissues during X-ray or CT scans. Contain a set of substances that are safe for patients and allow the X-rays to be stopped, so that the organs will be seen in greater detail in the test.

For example, to examine the circulatory system, an iodine-based intravenous contrast medium is injected into the bloodstream to illuminate the blood vessels.

What is CT used for?

CT is used as a clinical diagnostic test, in follow-up studies to analyze the patient's health status, in radiotherapy treatment planning, and even for screening asymptomatic individuals with specific risk factors. A computed tomography scan creates detailed images of the bodywhich include the brain, thorax, spine and abdomen.. Specifically, we can highlight the following uses:

• To help diagnose the presence of a cancer or tumor.. It is one of the most widely used techniques to screen for the presence of colorectal cancer and lung cancer.
• Obtain information about the stage of a cancer.
• Determine if a cancer reacts to treatment.
• To detect the return or recurrence of a tumor.
• Diagnose an infection.
• Support technique to guide a biopsy procedure.
• To guide some local treatmentssuch as cryotherapy, radiofrequency ablation and radioactive seed implantation.
• Radiotherapy planning external beam or surgery.
• Study the blood vessels.

When did computed tomography come into being?

Computed tomography was introduced in 1971 as an X-ray modality. which allowed axial images of the brain to be obtained, so it was a clinical method used specifically in the neuroradiology area. Its evolution has made CT a versatile imaging technique with which three-dimensional images of any anatomical area can be obtained. Currently, it is a diagnostic imaging equipment with a wide range of diagnostic capabilities. wide range of medical applications in oncology, vascular radiology, cardiology, traumatology or interventional radiology.

Evolution: From its beginnings to the present day

At 1971The following were developed first CT scanners for clinical use. During these early years, the EMI-scanner was used, with which brain data could be obtained and the calculation time per image was about 7 minutes in total. Soon after, scanners applicable to any part of the body were developed. At 1973In the early 1990s, the axial scannerswhose equipment had only one single row of X-ray detectors. Subsequently, it was when the helical or spiral scannerswhich incorporated multiple detector rowsits clinical use had a significant impact on the widely used and are the ones currently in use.

Current CT equipment: Main improvements and types

The evolution of the medical equipment has made it possible to obtain significant improvements. In today's systems, the image quality and offer both a better quality of life and a better spatial resolution as a low contrast resolution. In addition, nowadays, the following are also available CT scanners designed for specific clinical applications. Among them, we can highlight:

• Specific CT equipment for radiotherapy treatment planning: These scanners offer a larger aperture diameter than usual, thus allowing a study with a wider field of view. Thus, the images generated have greater detail and clarity.
• Hybrid equipment integrating CT scanners with other imaging techniquesHybrid solutions are now available. Among them, we can highlight the CT scanner incorporating a positron emission tomograph (PET) or a single photon emission tomograph (SPECT).
• Specialized scanners for new indications in diagnostic imagingDual-source" CT scanners, which are equipped with two X-ray tubes, have been developed, as well as "volumetric" CT scanners, which incorporate up to 320 detector rows, making it possible to obtain complete data on the organs analyzed in a single use.

Main risks

CT scans can diagnose serious diseases and conditions such as cancer, hemorrhage or blood clots. An early diagnosis is essential in order to find a solution as soon as possible and save lives. However, it is true that it is a test that presents some risks that are important to discuss:

X-Ray

One of the main risks of CT is that it utilizes the X-rayswhich produce ionizing radiation. This type of radiation can have certain effects on the organism and it is a risk that increases with the number of exposures to which a person is subjected. However, the risk of developing cancer by the radiation emitted by the X-rays is generally low.

Use in pregnant women and children

In the case of pregnant women, there are no risks for the baby if the area of the body being imaged is not the abdomen or pelvis. But, medical professionals often perform tests that do not use radiation, such as the magnetic resonance imaging or ultrasound. As for the childrenare more sensitive to ionizing radiationas they have a longer life expectancy and the risk of developing cancer may be higher compared to adults.

Reactions to contrast medium

On the other hand, another aspect to be highlighted is that some patients may have allergic reactions to contrast medium and, in very specific cases, temporary renal insufficiency. In this situation, intravenous contrast media should not be administered to patients with abnormal renal function.

Conclusion

As we have been able to analyze, computed tomography or CT is very useful for detailed and precise analysis of certain internal tissues and organs. By means of X-rays, certain conditions or serious diseases can be studied, which is why it is essential for clinical diagnosis and its application in different fields of medicine.
