MEDI12002 - Science and Instrumentation 1

General Information

Unit Synopsis

This unit focuses on the the main steps in producing a useful digital radiograph. You will learn to control of the x-ray beam's production and passage through the structures by judicious selection of technical factors. You will learn to control scatter radiation and recognise its impact on radiographs. You will harness image geometry concepts to control structural appearances on radiographs. You will explore basic concepts of digital imaging technology with a focus on clinical skill in the production, display, manipulation, storage and distribution of digital radiographs. You will become familiar with the attributes of radiographic image quality and the many factors that impact on those attributes.

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. Online Test 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: SUTE
Feedback
Clarity of quizzes and expectations was identified by a few students as an area for improvement.
Recommendation
Consider some example responses to the online tests to demonstrate varying levels of response.
Action Taken
Clarity of quiz expectations has been addressed through the provision of detailed breakdowns of the assessment format including numbers and types of questions, associated marks and recommended time budgets.
Source: SUTE and Unit Coordinator
Feedback
The unit includes authentic real-world problems throughout the content and assessment tasks.
Recommendation
Continue to include real-world clinical scenarios in quizzes and unit content.
Action Taken
The use of real-world scenarios in assessment tasks and tutorials has been maintained.
Source: CQUniversity Student Academic Integrity Policy and Procedure
Feedback
The current assessment strategy of online tests does not require 'at the ready' level of knowledge and provides opportunities for breaches of academic integrity.
Recommendation
Consider assessment strategies that will minimise opportunities for academic integrity breaches, such as supervised closed-book tests.
Action Taken
The online test questions included more scenario-based application and interpretation style questions to reduce over-reliance on external sources. The final online test was replaced by an invigilated in class test to reduce opportunities for breaches of academic integrity. These changes further support assessment of 'at the ready' level of knowledge.
Source: Unit teaching team
Feedback
Post-processing steps that are required for labs are sometimes unfamiliar or unclear.
Recommendation
Consider some additional pictorial guides for specific post-processing requirements in labs.
Action Taken
Laboratory instructions for initial labs included pictorial guides to facilitate the use of workstation interfaces when post processing images.
Source: SUTE and Unit Coordinator reflection.
Feedback
Students found the use of MS Forms effective in creating an inclusive learning environment.
Recommendation
Investigate the option to continue the use of MS Forms or similar tools in future iterations to support an inclusive learning environment.
Action Taken
Nil.

Feedback
Pre-lab activities were found to be beneficial in making links between weekly content and laboratory tasks.
Recommendation
Continue with the use of pre-lab activities to support the link between weekly content and laboratory tasks.
Action Taken
Nil.
Source: Unit Coordinator reflection and informal student feedback.
Feedback
Student engagement in self-directed learning related to Direct Read (DR) Digital Radiography systems was notably poor despite the availability of resources providing appropriate coverage of content.
Recommendation
Notify students in the lead up to content on Direct Read (DR) Digital Radiography systems that to meet the weekly learning goals they will be required to invest more time in self-directed learning, making use of the weekly reading materials as well as the lectures.
Action Taken
Nil.
Source: Unit coordinator reflection.
Feedback
The invigilated in class assessments supported maintaining of academic integrity.
Recommendation
Continue with the adaptation of invigilated in class tests as the final assessment for the unit.
Action Taken
Nil.
Unit learning Outcomes

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

  1. Use technical terminology correctly in describing radiographic image appearances
  2. Apply concepts of image geometry, differential attenuation, scatter production and equipment operation to control radiographic image appearances
  3. Make reasoned adjustments to technical factor selections according to the attenuating properties of the structures being imaged and the requirements of the imaging system
  4. Discuss at a basic level the clinical operation of the various digital radiographic image receptors and processing systems
  5. Discuss at a basic level core concepts of digital image properties, display, manipulation and storage.
