PACS system: differences between digital and conventional radiography

The X-ray scans are part of the routine of Health organizations, facilitating the diagnosis and monitoring of numerous diseases. The progress of digital radiography, through the PACS system¬† (Picture Archiving and Communication System), has changed the way Health professionals have access to the images, which are available at the moment in which the procedure is done, speeding up the preparation of the medical report and the routine of assistance. With the cloud computing allied to the model, the results are arranged where they are needed – in the office computer, in the operating room tablet or the doctor’s smartphone.

The digital radiography is based on the same principles of X-ray emission and its interaction with the human organism as conventional. The main difference between them is like the rays that pass through the matter that will be captured and processed to generate the image. In the traditional, radiographic plates are used that go through revelation. Already in direct digital radiography, X-rays are obtained by a circuit board sensitive to radiation, which generates a digital image and sends it to the computer in the form of electrical signals.

The test is accessed, processed and stored by PACS, which can be connected directly to the Patient Electronic Health Record (PEHP). In the indirect digital, the rays are captured by a phosphor plate that needs to be digitized for the image to be transmitted to the computer. Since then, it can be processed and destined for the most different premises, in the same way as direct radiography.

With this, one of the main disadvantages of conventional radiology is eliminated: the process of revealing the radiography. This stage generates toxic substances that pollute the environment. The proper radiography that was discarded over the years contributed to the generation of garbage. However, the disclosure process is done at least one hour, in the digital system the image is generated in seconds, optimizing the entire production process of the medical report. In addition to the advantages of top healthcare consulting firms in India, there is no need for extensive paper files to store conventionally printed exams.

Another difference between the two types of examination is in the quality of the images. In conventional radiography, the emission of the exact amount of radiation is necessary.  An error in the dose can generate a much or little-contrasted image, which will not allow the identification of injuries with security. Same with the perfect technique, considering that the sharpness and contrast of conventional radiography are naturally lower, the patient is exposed to a higher amount of radiation than in the case of digital radiography so that an image of the same quality is produced.

The image processed by PACS has more sharpness, contrast, details, and differentiation of densities than conventional radiography, which optimizes the diagnosis and monitoring of diseases. As it is immediately generated in the computer, it can be quickly sent to the radiologist. That professional then issues the medical report for a remote specialist or for the doctor responsible for the patient who can already diagnose and initiate the appropriate treatment, thus providing greater agility and efficiency throughout the care process.

The hospital consultancy services in India optimizes the processing of the image in the computer, which allows the adjustment of the contrast, the equalization by histogram and even the subtraction of images to favor the identification of injuries.
