15 credit Masters level module
About this course
Page last updated 26 September 2019
On successful completion of the Computed Tomography Technology module, students will be able to:
- Demonstrate a systematic understanding of the physics and technology of computed tomography.
- Critically evaluate the technical quality of CT images to determine errors and determine remedial action.
- Critically evaluate current CT principles, safety, legislation, dosimetry and guidelines and apply these appropriately in a clinical setting.
- Critically analyse a range of image reformatting and post processing technologies.
- Demonstrate an in depth understanding of digital archiving systems, system networking and data transfer within Diagnostic Imaging/Radiotherapy practice.
You must have a radiography professional qualification or relevant clinical Computed Tomography (CT) experience.
- Scientific principles of CT equipment, technology development and terminology, including the different generations of CT scanners.
- Fundamental specifics of CT equipment within a radiotherapy / hybrid imaging environment.
- Equipment development from a detector perspective and subsequent impact upon current / future working practice. Dual source systems, detector panel developments, cone beam.
- Equipment procurement suitability for service for current and future use.
- Equipment positioning aids in diagnostic and radiotherapy practice.
- 4D CT; cardiac and respiratory gating.
Safe working practice
- CT examination dosimetry and including verification / planning dose.
- Radiation protection (patient and staff), current regulations and other relevant legislation, and guidelines, isodose curves.
- Fundamentals of image formation in CT (incl. filtered back projection /reconstruction factors/ iterative reconstruction).
- Dose modulation principles & application to clinical practice.
- Scientific principles of modern contrast injector systems and application to clinical practice.
Image quality and quality assurance
- Image quality factors affecting this.
- Fundamentals of image re-formatting (3D, maximum intensity projections (MIPs), multiplanar reconstruction (MPR)) and image fusion (software & hardware based).
- Reformatting data for radiotherapy planning (Digital Imaging and Communication in Medicine (DICOM) RT) and data archiving /Picture archiving and communication system(PACS) networks.
- Quality Assurance and control tests in CT, reasoning behind tests, protocols and current legal and recommended requirements of such.
- Detecting image artefacts in CT, equipment faults and problem solving.
Learning and Teaching
- The teaching and learning strategy will embrace a series of vodcasts and self-directed activities presented via the VLE. Students will also engage in knowledge construction peer learning and social constructivism through work on the wiki.
- The wiki will provide a medium for tutor facilitation and formative feedback/feedforward.
Keynote lectures presented as vodcasts, wiki facilitation
Essential reading, wiki writing, group work, assessment preparation.
This module is completed over 10 weeks with you being expected to fully contribute each week. Whilst this can be done in your own time, it is highly recommended that you look to negotiate regular study time, recommended at half day a week equivalent, with your manager.
Working in groups, students will write a Wiki throughout the run of the module. The wiki will be themed on the learning outcomes and drawing from lecture/ vodcast content and material from independent study. Grades will reflect individual contribution and academic performance.
The creation of the wiki is very much a learning process and therefore this component of assessment takes an assessment for learning approach. The wiki will be facilitated by a tutor who will be able to provide formative feedback/feedforward.
- The individual contribution to a wiki.
