MEDI12002 - Imaging Science 2

General Information

Unit Synopsis

This unit covers the essential steps in creating useful digital radiographs. You will learn how the x-ray beam's interaction with various structures influences radiographic image appearances and how to use image geometry concepts to manage the depiction of structures on radiographs. You will become familiar with the key attributes of radiographic image quality and the factors that affect them. You will learn to control scatter radiation and understand its impact on radiographs. You will explore digital imaging technology with a focus on clinical skills in the production, display, manipulation, storage and distribution of digital radiographs. You will apply concepts of signal processing and image post-processing to effectively manage radiographic appearances.

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. In-class Test(s) 40%
2. In-class Test(s) 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 feedback.
Feedback
Week 12 use of lab time for students to work on test style questions and tutorial time to work through the answers to these questions was well recieved.
Recommendation
Consider maintaining the use of class time to practice test style questions in the week prior to the assessment in future iterations.
Action Taken
The final week's tutorial was dedicated to reviewing and consolidating unit content to reinforce understanding, ensure alignment with the overall unit learning goals and support students in preparing for their final assessment.
Source: Staff observation.
Feedback
Use of pre-lab videos improved lab preparation with students being more aware of how the lab activities were to be carried out, and having a better understanding of how the unit content related to the lab activity.
Recommendation
Explore the option to continue the use of lab preparation videos in future deliveries.
Action Taken
The use of pre-lab videos was not implemented for all lab sessions. Instead, students received a briefing at the start of each lab session outlining expectations and clarifying how the activities aligned with the intended learning goals.
Source: Unit coordinator
Feedback
Transitioning from an online test to in-class supervised tests appears to have better supported student preparation, performance and fairness.
Recommendation
Explore the option to continue with in-class supervised tests in future iterations to reinforce deeper learning over rote memorisation and provide a more structured, equitable environment for demonstrating knowledge and skills.
Action Taken
In Progress

Feedback
Students valued the use of small groups during tutorials and lab activities as it promoted interaction, peer learning and better engagement with the unit content.
Recommendation
Invest in continuing with incorporating small group activities in tutorials and lab sessions in future deliveries to strengthen peer interactions, engagement and collaborative learning.
Action Taken

Feedback
Students may benefit from more varied and updated learning resources to complement existing materials and support diverse learning preferences.
Recommendation
Conduct a review of existing learning resources and update selected lecture recordings to enrich learning and improve student engagement.

Unit learning Outcomes

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

  1. Use technical terminology correctly in describing radiographic image appearances and underlying factors that contributed to those appearances
  2. Discuss and apply concepts of image geometry, differential attenuation, scatter production and equipment operation to the evaluation of image quality and the control of radiographic image appearances
  3. Apply concepts of digital image signal techniques including capture, conversion, processing, post-processing and display to effectively manage and optimise the stored content and displayed image.
  4. Discuss the clinical operation of digital radiographic image receptors, processing systems and image information management systems.
