Aims of Module
The aim of the module is to provide the student with a basic understanding of the physical principles which underpin radiographic imaging and associated technology. The module will also enable the student to understand how x-rays interact with matter and how this is utilised to produce radiographic images with the lowest possible danger to the patient and the operator.
Learning Outcomes for Module
On completion of this module, students are expected to be able to:
| 1. |
Describe the basic principles of energy and energy transfer.
|
| 2. |
Describe the production of the x-ray beam, its interactions with matter and the factors which affect the quality and quantity of the x-ray beam.
|
| 3. |
Discuss radiation protection and safety within radiology.
|
| 4. |
Discuss the production of the radiographic image using photographic and digital media.
|
Indicative Module Content
The module will cover the basic physical principles of atomic structure, energy and energy transfer. The module will go on to consider x-ray production and the design features of a modern x-ray tube. The student will learn the mechanisms for evaluatuion of the x-ray beam and the factors which impact on beam quality and quantity. Interactions of x-rays with matter and how these affect the quality of the final image and the radiation dose to patients and staff will be considered. Radiation protection and other health and safety issues unique to diagnostic imaging will be reviewed alongside the appropraite legislation and guidance material. The module will also introduce basic photographic principles including film/screen imaging and imaging using digital media.
