Unit of study_
MRTY5134: Computed Tomography Theory
2024 unit information
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.

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. apply a thorough theoretical understanding of the effects of CT acquisition parameters on image quality and radiation dose
- 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

Important enrolment information
Departmental permission requirements
If you see the ‘Departmental Permission’ tag below a session, it means you need faculty or school approval to enrol. This may be because it’s an advanced unit, clinical placement, offshore unit, internship or there are limited places available.
You will be prompted to apply for departmental permission when you select this unit in Sydney Student.
Read our information on departmental permission.
Additional advice
This unit requires Departmental Permission only for UG students enrolled in the Bachelor of Applied Science (Diagnostic Radiography) and will be assessed if they have completed 96cp of units with WAM of 75 or higher. Students enrolled in the PG Medical Imaging will automatically be permitted to enrol after they have applied for Department Permission.
