Digital Healthcare Solution


The digital radiography and imaging department at Unison offers the most advanced imaging services in a comfortable and safe environment. The sophisticated facility is equipped with the latest machinery for digital X-rays and scans. We ensure high-quality images in a timely manner, so that the healing and treatment of patients can begin immediately.

Our skilled radiologists work in collaboration with other healthcare professionals to promptly diagnose and treat patients accurately.

Some of the services we offer under digital radiography include:

  • Radiological examination of the abdomen, chest, and spine
  • Urological investigations including IV urogram and Retrogrde Urethrogram (RU)
  • Portable radiography
  • Radiography fluoroscopy with an angiography facility

There are 4 steps in digital radiography:

  • image generation
  • processing
  • archiving
  • presentation

Image Acquisition and

Digital detection is based on the conversion of absorbed X-ray energy into electrical charge, which must then be represented digitally in grayscale images to show the quantified X-ray energy that was absorbed at each point in the digital image. The final image is produced using processing software. The purpose of image processing is to improve image quality by reducing noise, eliminating artifacts, and enhancing contrast if necessary.


Image Archiving and

Final images are stored digitally on storage media for viewing on a computer. While being viewed, the images may be zoomed, measured,for distance and angle, panned or windowed. Images can be sent to other computers for remote viewing, or linked to digital record systems for improved retrieval and diagnosis.

The basic principle, therefore, is to detect X-rays, then convert the X-rays to charge directly or indirectly (via conversion to light as the first step by phosphors or scintillators). These images are processed and viewed digitally. The process takes 10 seconds or less, and requires no cassette.
