This section provides knowledge and understanding of X-rays, CAT scans, PET scans and ultrasound scans. This section shows how the developments in medical imaging have led to a number of valuable non-invasive techniques used in hospitals.

The lesson-by-lesson schedule is as follows:

  • X-Rays and Their Production
  • Attenuation of X-Rays
  • X-Ray Imaging (Contrast media and CAT scanning)
  • The Gamma Camera and PET Scanning
  • (Additional Information on MRI Scans – but not in the specification!)
  • Ultrasound
  • Acoustic Impedance
  • The Doppler Effect
  • Review and Test Materials
