MEDI12007 Quality Processes for Dose and Image Optimisation
Quality Processes for Dose and Image Optimisation
All details in this unit profile for MEDI12007 have been officially approved by CQUniversity and represent a learning partnership between the University and you (our student).
The information will not be changed unless absolutely necessary and any change will be clearly indicated by an approved correction included in the profile.
General Information


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, document findings and determine corrective action. You will consider imaging quality processes in the larger context of facility quality management and compliance with external standards. You will investigate the impact of technical factor selection on patient dose and image quality. Through these you will learn to make informed selections and modifications 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).

Residential Schools

This unit has a Compulsory Residential School for distance mode students and the details are:

Assessment Grading

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%). Consult the University’s Grades and Results Policy for more details of interim results and final grades.

Previous Student Feedback

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.

Feedback from Unit Coordinator self-reflection Informal feedback from students


The 3-day residential school was well received by students.


Retain the 3-day res school to support students with integration of the theory and application of concepts in future iterations of the unit.

Feedback from Unit Coordinator self-reflection Informal feedback from students SUTE feedback


Having application type questions in the weekly tutorials supported student learning and consolidation of the key concepts learned.


Continue the adaptation of application type questions in the review and consolidation of content in the weekly tutorials.

Unit Learning Outcomes
On successful completion of this unit, you will be able to:
  1. Assess the performance of radiographic, fluoroscopic 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 structures demonstrated on 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 technical parameter selection to address dose and image optimisation
  6. Discuss the interconnections of imaging quality control, dose management, departmental quality management and compliance with external quality and safety standards for clinical imaging facilities.

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 1A Diagnostic radiographer:

  • 1. Perform projection radiography examinations in a range of settings.
    • a. Operate projection radiography systems safely and effectively in a range of settings
    • c. Use standard radiographic projections and exposure factors for the patient's/client's body area being examined and, when appropriate, modify them to consider patient/client presentation, clincal indications and mechanisms of injury
    • f. Critically evaluate images against radiographic criteria including assessment of exposure index, field of view and anatomical rotation
    • g. Collaborate in the design and evaluation of projection radiography protocols.

Domain 2: Professional and ethical practitioner:

  • 3. Take responsibility and accountability for professional decisions.
    • c. Integrate organisational policies and guidelines with professional standards and apply to practice.

Domain 4: Evidence-informed practitioner:
