Role of modern radiology digital imaging and PACS in health care

Over the years there have been made several advancements in medical science. As result love you getting better health you and also give that has input to a greater extent as compared to the last few years.

The medical practitioner all over the world now takes the help of advanced digital medical systems and equipment for diagnosing their patients and to find the disease or disorder. For many years radiography has been a prominent choice of medical practitioners for diagnosing the disorders of bones and other internal organs.

Since the advent of advanced computed radiology digital imaging past two decades ago, it has completely transformed radiological imaging. The modern radiology is different from the past. The modern radiology allows doctors to easily store and retrieve imagery of scanning as and when they want it. The time has gone when people need to store X-ray films and scanned copies in various folders and files which was a troublesome job.

Cloud Storage

With the help of cloud storage, the storage and backup of scanned copies and films are easy. The practitioners can now easily access the films on the go on their mobile and computers.

Radiography is used for various examinations and medical diagnosis to capture a static image through which it will be easy for the doctors to diagnose the disease.

It is mostly used in:

  • Dental examination
  • Verification of correct placement of surgical markers before invasive procedures
  • Mammography
  • Orthopaedic examinations
  • Chiropractic diagnosis
  • Kidney and liver disorders

X rays which were discovered in 1895 by professor Wilhelm Roentgen of Germany was a great invention of using the vitality of emissions from electric current in a vacuum. When the electricity was transferred between two electrodes in a cathode ray tube it formulates a glow that appears in barium platinocyanide coated screen. In the last few years, many changes were made in X-Ray technology.

Today, radiological facilities are available in every hospital and health care unit. For many years the radiology has been the backbone of magical science helped many patients to get free from viral diseases and also helped many practitioners in learning more concepts of radiology.

The development of computer technology has brought measurable changes in radiography. The introduction of filmless radiology was a great virtue for all medical professionals. Digital radiography was first used in the mid‐1980s and, with a rise in its popularity; it is also used with conventional screen-film radiography (SFR) in various applications.

Clinical applications and diagnostic role

Radiographs are the first step in the diagnosis of various clinical situations. Conventional radiography or SFR is used much largely than digital radiography. One of the reasons why SFR are least preferred by many radiologists because of its limited potential. Various parameters limit the information to be captured and transformed into a film. The biggest drawback is it is that its images cannot be contrasted once they are processed. It also uses the film that is expensive with hazardous materials that makes it difficult for processing. The long term storage of film is not easy in SFR. It is also not compatible with PACs that is the picture archiving and communication systems.

Digital radiography (DR) has different forms. Instead of the conventional film, it uses a photostimulable phosphor plate for x rays. This plate is then scanned with helium-neon laser and the emitted light is triggered using a photomultiplier tube. There is also a form known as DR known as direct radiography that uses a semiconductor to converts X-ray beams into electrical signals, thus eliminating latent image. There are also used Solid-state detectors and flat-panel detectors to transmute x-ray photon into the light.

Radiographic imaging equipment

X Rays are created by high energy electrons. The conventional radiography, x rays are passed through the human body that is absorbed causing resemblance of the incident beam. The regular x-ray beam is directed through the human body to capture imagery on the film.

Radiography is the focal point of Modern Medicine

Radiographer has the required qualification to operate this most advanced equipment of medical science. A radiologist plays an important role in patient diagnosis as he works closely with the doctors. A radiologist is trained to take important diagnostic tests like:

X-Rays: This uses radiation to inspect the body from inside for broken bones and another internal bleeding.

Fluoroscopy: It helps to create real-time images of the digestive system.

MRI (Magnetic Resonance Imaging): It creates 2D and 3D images with the help of magnetic imaging. It is mostly used for brain scanning to find brain injuries.

CT (Computed Tomography): It helps in creating cross-section views of areas of the body

Angiography: It is used to check blood vessels.Radiographers Play a Vital Role in Healthcare

The doctors mostly rely on diagnostic tests that radiography equipment provides.

PACS Medical imaging

PACS (picture archiving and communication system) is an imaging technology that is used by the hospitals and health care services to create and store digitally transmitted electronic images and reports. PACS medical imaginghas helped in eliminating the traditional way of file storage and other information like films and reports. Now all the important medical documents and images can be stored in off-site servers and can be accessed from anywhere using PACS software on mobile or PC.

The modern Medical imaging storage technology PACS is important for storing and retrieving a high volume of digital medical images that are very useful for healthcare practitioners and medical emergency services.

Who uses PACS?

Many radiologists use PACS because of its quality to produce X-ray images that are used largely in nuclear medicine imaging, cardiology, pathology, oncology and dermatology.

Medical images are ve and reviewed for clinical analysis, diagnosis and treatment as part of a patient’s care plan. The information collected can be used to identify any anatomical and physiological abnormalities, chart the progress of treatment and provide clinicians with a database of normal patient scans for later reference.

Having digital access to the most updated version of a patient’s medical images, clinical reports, and history can expedite and improve care, lessening the likelihood of treatment and prescription errors, and preventing redundant testing. Digital access can also improve patient safety and save both the healthcare facility and the patient time and money.
