Curricular information is subject to change.

This module provides you with the fundamental knowledge that underpins Computed Tomography (CT) protocols, technology, and image processing. It addresses a broad spectrum of clinical scenarios and some basic image appearances to demonstrate the clinical utility of the modality. The module will incorporate lectures, tutorials, student-directed e-learning and quizzes and the theoretical learning will be supported by image review sessions. Spring 2025 trimester lectures will be delivered in-person at UCD. To undertake this module you must have already passed Clinical Practice of Radiography RDGY20180.


About this Module

Learning Outcomes:

Throughout this module, you will develop knowledge, professional skills and personal attributes relevant to your future radiographic practice and at the end of this module you should be able to:

1. Explain the fundamental principles underpinning CT scanner technology, data acquisition and image reconstruction.

2. Explain the fundamental principles underpinning CT image display, image quality and post-processing of CT images.

3. Explain the relevant CT protocols or scanning approach for a given clinical scenarios or clinical indication.

4. Discuss principles underpinning patient care, patient safety (radiation safety, benefit/risk, infection control) and consent for CT examinations.

5. Discuss the methods and application of contrast agents to CT patients;

6. Discuss how the various components of CT protocols (scan and reconstruction parameters) influence radiation dose, image quality or imaging outcomes.

7. Explain principles of quality assurance/control in CT including image quality issues and artefacts.

8. Demonstrate an ability to identify and describe basic anatomy and pathology on CT images identified in the module.

Indicative Module Content:

The syllabus will encourage you to consider technological and clinical practice issues to include: Components of a CT scanner, CT scan and reconstruction parameters, digital image display, image quality, CT radiation dose, advanced processing, and the need for quality assurance in CT. Patient care and preparation, clinical indications, scan protocols, and basic image appearances will be considered for a range of anatomical areas. Professional role of CT radiographer will be linked in with various topics in the module.

Approaches to Teaching and Learning:
The CT module is delivered during the Spring Trimester.
Technology of CT topics are introduced using a blended approach using a combination of e-learning and face-to-facet or tutorial sessions. The e-learning must be completed in advance of the tutorial on that topic. Learning is further supported through quizzes, & discussion boards.
Clinical application of CT topics are delivered face-to-face and are further supported through image review sessions to illustrate pathology and image quality. Students must engage with image review in order to consolidate learning on the topic and to enable identification or description of CT image appearances under exam/assessment conditions.

Citation methods used on on this module should be Harvard referencing style.

Generative AI use policy on module
Students may use AI tools for limited support in this module (e.g. idea generation, practice questions, or as a study aid). However, students remain fully responsible for the accuracy and reliability of their learning. Any use of AI must be cited appropriately.
The assessment is completed entirely without AI assistance, ensuring that students rely solely on their existing knowledge, understanding, and skills.
