Learning Outcomes

Knowledge and Understanding

  • Explain the principles of analogue and digital imaging systems and hardcopy production.
  • Describe the construction and operation of rotating anode x-ray tubes and high tension cables.
  • Describe the interaction processes of x-ray photons with matter and their significance to image production and radiotherapy.
  • Demonstrate the ability to perform simple experiments using ionising radiation safely and to interpret results.
  • Either (diagnostic radiography) explain the design features of static x-ray imaging equipment or (radiotherapy) the design features of kilovoltage x-ray units and the construction and function of the medical linear accelerator.

Intellectual Skills

  • Demonstrate the ability to perform x-ray geometry/output calculations.
  • Outline the principles of x-ray generator/filament/timer circuit design.
  • Describe the construction and operation of the image intensifier.
  • Explain the principles of radioactive decay
  • Demonstrate the ability to predict the activity of a radioactive source at a given time.

Subject/Professional and Practical Skills

  • Outline the chemical and biological effects of ionising radiation on the cell.
  • Describe the principles, common applications, advantages/limitations of the imaging modalities.

Transferable Skills and other attributes

  • Demonstrate a knowledge and understanding of the principles of radiation protection and current UK regulations/recommendations with reference to patients, staff and members of the public/carers in either diagnostic imaging or radiotherapy.

Reading Strategy

Reading Strategy

Students will be directed to reading which is either available electronically or provided for them in a printed study pack. They will also be expected to read more widely by identifying relevant material using the Module Handbook, the Library Catalogue and resources such as those listed below:
