MRS561 Computerised Tomography Physics and Instrumentation (8)

CSU Discipline Area: Medical Radiation Science (MEDRA)

Duration: One session

Abstract:

This subject covers the concepts of physics and instrumentation in the field of computerised tomography (CT). It briefly reviews the basic physic principles of CT and extensively considers the physics of advanced techniques including Helical CT and Electron Beam CT. It covers reconstruction techniques used in CT, especially those in Helical CT. The subject reviews the basics of 3D image formation techniques used in orthopaedic and CT angiography. The subject also covers the design of CT instrumentation such as the detectors and slip rings. Radiation safety in CT will also be covered.
