MEDP5332MX-ray Computed Tomography

This module is not approved as a discovery module

Module summary

This module describes the scientific principles and techniques employed by modern computed tomography systems. Students will develop an appreciation of the wide range of computed tomography technology available and see how this technology is applied in a number of clinical areas.


This module will provide a detailed understanding of the physical principles of medical X-ray computed tomography and give an appreciation of its role in patient diagnosis and treatment.

Learning outcomes
At the end of the module, students will be able to:

1. Demonstrate an understanding of the physical principles under-pinning modern computed tomography
2. Recognise the most important technologies currently utilised in computed tomography
3. Describe the different designs of current computed tomography imaging equipment and techniques employed
4. Describe the chain of physical and technical processes contributing to the successful formation, acquisition, processing and display of computed tomography images
5. Recognise relevant physical characteristics of computed tomography images
6. Recognise the fundamental trade-off between image quality and radiation dose to the patient
7. Appreciate the complimentary roles computed tomography plays alongside other medical imaging modalities in medical diagnosis

Skills outcomes
The underlying science of computed tomography imaging is fundamental to a wide range of clinical applications in radiology and radiography. The module will benefit radiology and radiography practitioners, and will benefit those involved in computed tomography and X-ray imaging research.
