Imaging with Ionising Radiation (SPE101)

10 credits

Aim of this module

To introduce the trainee to a range of equipment and techniques used in Nuclear Medicine and Diagnostic Radiology and understand the effects of image acquisition parameters and post processing.

  1. Demonstrate safe practice when working with sources of ionising radiation, including X-ray equipment, sealed and unsealed radioactive material.
  2. Assist in routine patient investigations using uptake counters, gamma spectrometers, manual and automatic beta and gamma sample counters correctly and safely, and, where possible, other equipment such as whole body counters, demonstrating patient-centred, safe practice and the effect of equipment settings and counting geometry on measured count-rates.
  3. Perform a range of procedures in the radiopharmacy correctly and safely, including quality assurance tests of facilities, products, equipment and radionuclide calibrators.
  4. Handle sealed and unsealed radioactive sources safely and use safe practice when working with X-ray equipment.
  5. Operate radiographic and fluoroscopic equipment for the purpose of performance testing and undertake performance tests on a basic range of X-ray equipment.
  6. Make and collate patient dose measurements, calculating patient doses for a range of examinations, including the calculation of foetal dose.
