MEDI12007 - Quality Processes for Dose and Image Optimisation

General Information

Unit Synopsis

You will apply knowledge of equipment operation and use as well as radiographic image acquisition techniques to the optimisation of radiographic images and patient dose. You will apply the concepts of quality control testing and quality assurance to monitor equipment performance, detect performance issues and document findings. You will investigate the impact of technical factor selection on patient dose and image quality. Through these you will learn to make informed selections of technical parameters for radiographic procedures and to justify your decision-making.

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Practical and Written Assessment 40%
2. Online Test 60%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Feedback, Recommendations and Responses

Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.

Source: Student Have Your Say
Feedback
Students found the weekly tutorial a useful tool for learning.
Recommendation
Maintain the use of weekly tutorials to enable students to review and consolidate the weekly content.
Action Taken
The tutorials were held weekly using Zoom.
Source: Student Have Your Say Coordinator Reflection
Feedback
Some students struggled with understanding the assessment requirements and marking rubric(s).
Recommendation
Create instruction videos that focus on each assessment item. Include examples of poor and good approaches with respect to the marking rubric to encourage better understanding of the assessment requirements and marking rubric(s) by the students.
Action Taken
An instructional video to enable students to understand the assessment task requirements and the scoring guide was created for the assessment.
Source: Have your say Unit Coordinator self reflection
Feedback
The availability of shorter lecture videos have been well received by students.
Recommendation
Maintain the availability of shorter lecture video recordings for future iterations of the unit.

Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Assess the performance of radiographic and ancillary equipment relative to quality standards.
  2. Troubleshoot imaging faults and equipment problems
  3. Apply metrics of image quality to describe and evaluate visibility and accuracy of radiographic images
  4. Relate radiographic equipment performance and the selection of image acquisition and processing parameters to patient dose and image quality
  5. Critically appraise evidence to inform decision-making in balancing dose and image optimisation.

The unit links to the following Professional Capabilities for Medical Radiation Practitioners as detailed by the Medical Radiation Practice Board of Australia (effective March 2020):

Domain 4: Evidence-informed practitioner practitioner:

  • 1. Resolve challenges through application of critical thinking and reflective practice (Part a: Identify the challenge or question and the information that is needed to respond and Part b: Find, critically appraise, interpret and apply best available research evidence to inform clinical reasoning and professional decision-making)

Domain 5: Radiation safety and risk manager:

  • 1. Perform and provide safe radiation practice (Part a: Comply with relevant radiation safety legislation)
  • 3. Implement quality assurance processes imaging or treating patients/clients (Part a: Check and confirm that all equipment is in good order and operating within acceptable parameters, Part b: Follow protocols to record details of all routine equipment checks, Part c: Identify and take appropriate action to correct unacceptable condition or operation of all equipment & Part d: Follow protocols to record and report non-conformance of all equipment.
