RAD3051 · Medical imaging science and practice 1

Overview

Through completing this unit, you will develop an understanding of the principles and techniques behind effective and safe computed tomography (CT) imaging. The unit will enable you to compare different systems and the reconstruction methods involved in image acquisition and processing. You be able to understand CT artefacts, quality assurance processes and apply your knowledge of radiation protection and dosimetry into CT. You will develop clinical competency (knowledge and application) in the radiographic methods of CT examinations of the head, neck, chest, abdomen and spine. Building on cross-sectional anatomy and pathology knowledge from Year 2, you will apply this to clinical practice in CT. Continuing your development in General Radiography skills, you will progress to a ‘Competent Student Radiographer’ including contrast, trauma, paediatric and mobile imaging. Foundational knowledge of digital health systems will be further developed in the areas of digital image processing, computer interfaces, medical image formats, the DICOM standard, image compression and the hospital Picture Archiving and Communication System (PACS). The medicolegal aspect of healthcare will be introduced, and building on ethical practice from Years 1 and 2, you will be able to apply this knowledge to practice within an appropriate ethical and medico-legal framework. Having completed Allies in Indigenous Health I in Year 2, through completing Allies II in this unit, you will be empowered to provide culturally safe care to Aboriginal and Torres Strait Islander patients.

Assessment

The Handbook lists an examination for this unit.

Assessment in this unit includes hurdle assessment tasks. Failure of any hurdle assessment task may result in failure of the unit.

Assessment details may change. Please refer to the assessment information in Moodle closer to the start of the teaching period.

Requisites

Learning outcomes

1. Explain the scientific principles underpinning computed tomography;
2. Describe and represent the physical configuration of axial, helical and multislice CT systems;
3. Explain and distinguish between the various data acquisition and image reconstruction processes used in CT and their characteristics;
4. Identify common CT artefacts, explain their cause and suggest methods to correct for them;
5. Apply radiation protection and dosimetry principles to the practice of CT;
6. Describe the principles underpinning advanced digital image processing, image distribution, data transfer and storage options used in medical imaging (including the DICOM standard and PACS and RIS infrastructure).
7. Explain the clinical rationale for the selection of CT scanning protocols, image display and reconstruction methods for CT examinations of the head, neck, chest, abdomen and spine;
8. Implement and evaluate positioning methods, scanning protocols, image display and reconstruction routines for CT examinations of the head, neck, chest, abdomen and spine;
9. Identify the CT appearances of the anatomical structures comprising the head, chest, abdomen and spine and distinguish between normal and abnormal structures as shown on CT in a variety of relevant formats (e.g. MPRs, MIPs, VRs);
10. Reach the level of competent student radiographer in general radiography including contrast, trauma, paediatric and mobile imaging;
11. Apply evidence-based inquiry principles developed in second year to an advanced radiographic practice clinical issue;
12. Apply radiographic techniques and radiation protection strategies within an ethical and appropriate medico-legal framework in professional practice;
13. Perform a range of CT scans at the level of Advanced Beginner;
14. Critically evaluate and apply the knowledge, skills and attitudes required to collaboratively address cultural diversity in healthcare environments.

Workload

As this is a Work Integrated Unit there are both scheduled teaching activities and clinical placement time: 18 hours of teacher-directed study per week, including 2 hours of pre- and post-class activities via Moodle, 6 hours of interactive scheduled class time (including lectures, practicals, tutorials and workshops) and 10 hours (academic equivalent) of clinical placement. 18 hours of self-directed study per week.

Student experience, not official rules. Nothing here changes what the Handbook says.
