Assessment Tasks

1 Practical and Written Assessment

Assessment Title
Practical & Written Asessment

Task Description

In the medical imaging profession, radiographic image acquisition and patient dose is highly dependent on the use of correct technical parameters and proper equipment performance. This assessment requires you to apply the concepts learned in this unit to demonstrate your knowledge and understanding of the importance of optimising patient dose and image quality. The concepts assessed are relevant to your future scope of practice and you will build upon them in your future clinical capacity.

There are two parts to this assessment:


Part 1 - Group Report (20%)

  • You will work as a lab group to create a small-scale single-blind study of the impact of technical factor selection on image quality.
  • Half of the class will be assigned a test using a subjective measure of image quality and the other half will be assigned an objective measure of image quality.
  • Your group will create a set of images for the blind study, then administer the blinded test to the members of 3 other lab groups to collect data. Students assigned to conduct the subjective test will take part in the objective test for the other lab groups and vice versa.
  • You will then analyse your data using Receiver Operating Curves.
  • As a group, you will discuss your experimental findings, compare it with theory you have studied to date and make recommendations for clinical application of your findings, particularly in optimising patient dose and image quality.
  • There will be one report submitted per group with the images or list of images in PACS as supporting evidence of your work.

Part 2 - Individual Submission (20 %)

You will be presented with evidence (which may include radiographs and/r technical data) of an equipment problem. You will submit an individual write-up. Your write-up must:

  • include an introduction, conclusion and referencing
  • use relevant theory to analyse the information provided to identify the problem and discuss possible implications of the problem on technical factor selection for specific clinical situations, image quality and patient absorbed dose

Your submission must be a word-processed document with appropriate layout including relevant headings and sub-headings that enable information to be easily read.

  • Acceptable file types are Word document (either .doc or .docx format) or pdf file that is a conversion of a word-processed document (NOT an image file such as a scanned document).
  • All submissions must be processed through TURNITIN.
  • Ensure that your document includes a header with your name and student number and a footer with the unit code and term/year.

Please note that further details regarding the requirements for this assessment will be provided on the unit Moodle site.
