MEDI12007 - Radiation Dose, Safety and Quality Assurance

General Information

Unit Synopsis

Students will learn the elements of radiation dose and quality assurance and how to use them in order to produce consistently high quality images in a safe environment. Students will understand and implement the three principles of image production, justification, limitation and optimisation. Students will assess the equipment and accessories using specific tests to determine their state of performance and safety. Students will develop a Quality Assurance programme which can be implemented in the clinical setting.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability. See details in the Assessment Policy and Procedure (Higher Education Coursework).

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. Written Assessment 20%
2. Group Discussion 10%
3. Written Assessment 20%
4. Practical and Written Assessment 10%
5. Examination 40%

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: Informal student feedback and instructor observations.
Feedback
Students who had not covered the assigned theory content prior to attending the res school found it difficult to apply concepts to the lab activities at the res school then also struggled on the test to answer questions on the final online test that related to the lab activities.
Recommendation
Modify the assessment strategy to add a new in-class test at the start of the res school and reduce the weight of the final test.
Action Taken
A small-stakes in-class test was added. The weights for the final test and assignment were also adjusted.
Source: Unit coordinator reflection
Feedback
The structure of the newly designed written assignment and the schedule of res school activities resulted in very time-intensive lab school preparation and disttribution of assignment images and data to students after the res school. This impacted timely development of other new learning resources during the term.
Recommendation
Modify the res school schedule of activities to support more efficient data and image collection and distribution for the assignment.
Action Taken
Changes were made to some res school activities to support more efficient collection of data and images. Changes were also made to the assignment and distribution to each student of data for analysis.
Source: Informal student feedback
Feedback
The res school schedule included rotation of four small groups through multiple concurrent hands-on lab activities and classroom sessions. For some parts of the schedule, concurrently run activities took quite different quantities of time to complete. This was frustrating for some students.
Recommendation
Re-package the sets of lab activities for each session and modify the scope of the classroom sessions to have more consistent time requirements.
Action Taken
Lab activities were 'bundled' differently to achieve more consistent time requirements for concurrent activities.
Source: Marking team feedback
Feedback
The written assignment scoring was done using an online rubric with multiple criteria for each question to be answered. The online rubric tool design was not a good fit for the assignment design, although the assessment criteria were a good fit. Marking of assignments was inefficient.
Recommendation
Investigate the use of an online marking guide for a more efficient marking process.
Action Taken
An online marking guide for the written assessment was implemented.
Source: Informal student feedback, teaching team observations
Feedback
Students entered their lab data into the provided Excel-based workbook which automatically performed required calculations. Although efficient for lab test completion, it resulted in many students not understanding the data analysis processes.
Recommendation
Modify the lab workbook to remove the automatic calculations.
Action Taken
In Progress
Source: Informal student feedback, teaching team observations
Feedback
The three days of residential school was tightly packed with lab and classroom activities. Students had no independent study time to analyse their lab data or create summary notes to support retention of learning.
Recommendation
Modify the residential school schedule to incorporate time for data analysis and debriefing.
Action Taken
In Progress
Source: Informal student feedback, teaching team observations
Feedback
Many students had not completed the requisite learning activities in the first two weeks to prepare them for both the lab activities and the in-class test of the res school in the third week.
Recommendation
Send multiple targeted announcements and emails to students at the start of the unit to specify what needs to be completed prior to the res school and why.
Action Taken
In Progress
Unit learning Outcomes

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

  1. Discuss the regulation of radiation safety and quality assurance in clinical practice.
  2. Discuss the challenges inherent in the application of the principle of justification, limitation and optimisation to the practice of radiography.
  3. Apply knowledge of beam production and control, equipment operation and performance, differential attenuation and imaging technique to the goal of image optimisation with simultaneous dose limitation in radiographic practice.
  4. Discuss the purpose, scope and fundamental concepts of risk management, quality management, quality assurance and quality control in Medical Imaging.
  5. Assess performance of equipment and imaging systems relative to quality standards.
