MRTY5134: Computed Tomography Theory

This unit of study will provide a theoretical understanding of the science of computed tomography (CT). It will cover the basic physics of radiation attenuation, data acquisition, image reconstruction methods, and image display and recording. It will also include an overview of relevant post processing operations. Quality Assurance (QA) of CT scanners will be explored. Finally, CT radiation dose considerations, such as the measurement of Computed Tomography Dose Index (CTDI), the Dose Length Product (DLP), and the Effective Dose (ED), will be reviewed. The factors affecting dose will also be covered, along with approaches to reduce patient doses in the clinical setting.

Academic unit Clinical Imaging
Credit points 6

At the completion of this unit, you should be able to:

  • LO1. demonstrate a thorough theoretical and practical understanding of CT instrumentation, and the fundamental concepts underpinning data acquisition, image reconstruction, image processing, and display
  • LO2. demonstrate a thorough theoretical and practical understanding of common CT image quality and dose metrics, and the ability to measure them
  • LO3. design CT acquisition protocols that optimise CT image quality and dose for specific clinical imaging tasks
  • LO4. identify and differentiate common image artifacts in CT, their causes, and how they may be mitigated
  • LO5. critically evaluate the potential clinical impact of recent advances in CT technology
  • LO6. demonstrate a theoretical and practical understanding of CT QA and QC procedures
