IMAGING PHYSICS SECTION - RIYADH

926

Imaging Physics is a branch of medical physics, which is concerned, with the application of physics to the diagnosis of human disease. The main areas of interest are in diagnostic imaging with x-rays, ultrasound and nuclear magnetic resonance, and in the diagnostic/functional imaging of radioisotopes in nuclear medicine.

The Imaging Physics Section (IPS) primary responsibility has been to provide support services to the KFSH departments of Radiology, Cardiology, OR, and Dentistry (and surrounding satellite clinics), so as to ensure that optimal image quality is attained and maintained in all imaging modalities. Image quality is maintained in all of the following equipment:

  • Magnetic Resonance Imaging (MRI) scanners;
  • Computed Tomography (CT) scanners;
  • Positron Emission Tomography (PET) scanners;
  • Gamma cameras (with SPECT capabilities);
  • PET/CT and SPECT/CT scanners;
  • Radioisotope dose calibrators;
  • Ultrasound scanners;
  • Conventional and Digital/Computed Radiography (DR and CR);
  • Dental units;
  • Angiography suite;
  • Catheterization laboratory (Cath Lab) suites;
  • Portable C-arms and x-ray units (both conventional & digital);
  • Lithotripsy unit;
  • Mammography unit; and
  • Film processors and laser cameras

The IPS conducts a comprehensive quality control program, utilizing an assortment of state-of-the-art instrumentation for radiation detection and measurement, numerous quality control test tools, various industry standard imaging phantoms and vendor specific diagnostic software.

In addition to the above, the IPS staff is also involved in:

  • Performing dose calibrator calibrations;
  • Facilitating compliance of radiation emitting devices with international regulatory agencies;
  • Participating in medical imaging equipment selection committees;
  • Writing of new equipment specification tenders;
  • Performing commissioning (acceptance) testing of new equipment;
  • Providing assistance to the departments of Radiology and Biomedical Engineering, when addressing equipment vendor service support issues;
  • Providing clinical support services to radiologists on the optimization of imaging procedures and to technologists on the use of optimal examination techniques;
  • Assisting with clinical trials;
  • Evaluating and implementing new imaging technology; and
  • Participating in image quality and perception studies

The extensive testing equipment facilities and expertise makes it a frequent training facility for institutions of higher education in the Kingdom and for other facilities interested in establishing similar quality control program.
