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: 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.
Action Taken
Availability of shorter lecture videos has been maintained.
Source: Have your say Unit Coordinator self reflection
Feedback
Some students needed further assistance with understanding the assessment requirements and scoring.
Recommendation
Update the instructional video describing the assessment tasks to 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 for assessments was not used for 2021. Instead, including the assessment data collection and analysis as part of the res school activity under the unit coordinator's guidance helped students better understand the requirements for and execute the first assessment. Incorporating assessment type questions in the weekly tutorials also gave students insight about expectations and scoring of responses in preparation for the final online test.

Feedback
The 3-day residential school was well received by students.
Recommendation
Retain the 3-day res school to support students with integration of the theory and application of concepts in future iterations of the unit.
Action Taken
Nil.
Source: Unit Coordinator self-reflection Informal feedback from students SUTE feedback
Feedback
Having application type questions in the weekly tutorials supported student learning and consolidation of the key concepts learned.
Recommendation
Continue the adaptation of application type questions in the review and consolidation of content in the weekly tutorials.
Action Taken
Nil.
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.

Medical Radiation Practice Board of Australia's Professional Capabilities Standards (2019):

Domain 4 Capability 1. Resolve challenges through application of critical thinking and reflective practice.

Domain 5 Capability 1. Perform and provide safe radiation practice.

Domain 5 Capability 3. Implement quality assurance processes imaging or treating patients/clients.
