Module summary

This module will provide a detailed understanding of the science of modern medical X-ray imaging, and provide an appreciation of its role in modern medicine. The module covers the underlying scientific principles and technology of X-ray imaging, using example clinical applications to illustrate their relationship to practice.


This module will provide a detailed understanding of the physical principles of medical X-ray imaging 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 a detailed understanding of the physical principles under-pinning modern digital radiography
2. Recognise the most important technologies currently utilised in X-ray imaging
3. Describe the design of X-ray imaging equipment and techniques
4. Describe the chain of physical and technical processes contributing to the successful formation, acquisition, processing and display of X-ray images
5. Interpret the relevant physical characteristics of X-ray images
6. Recognise the fundamental trade-off between X-ray image quality and radiation dose to the patient in X-ray imaging
7. Appreciate the complimentary roles X-ray imaging plays alongside other medical imaging modalities in medical diagnosis

Skills outcomes
The science of X-ray imaging is fundamental to the practice of X-ray imaging in radiology or radiography, and will benefit those using X-ray images in research.
