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%).

Previous Feedback

Term 1 - 2021 : The overall satisfaction for students in the last offering of this course was 4.4 (on a 5 point Likert scale), based on a 24.49% response rate.

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, unit coordinator reflection, course staff.
Feedback
Recorded lectures provide students with flexibility in study times and the ability to re-watch or pause to support learning.
Recommendation
Use a flipped-classroom model with all recorded lectures and face-to-face labs and tutorials.
Action Taken
The unit used the flipped-classroom model with all recorded lectures and face-to-face labs and tutorials.
Source: Student feedback.
Feedback
Revision quizzes with feedback were helpful.
Recommendation
Continue with the use of the revision quizzes and include feedback to responses.
Action Taken
Weekly revision quizzes were continued with in-built feedback to many responses.
Source: Unit coordinator reflection
Feedback
The online quiz for the first assessment supports feedback and more timely return to students.
Recommendation
Investigate using an online Moodle quiz as the first assessment.
Action Taken
Online tests via Moodle were used for both assessment items.
Source: Unit coordinator and student 'Have your say' survey
Feedback
The activities in the labs and tutorials are a strong support to learning the content in this unit.
Recommendation
Continue with tutorial and lab activities.
Action Taken
Nil.
Source: Lab instructors and unit coordinator
Feedback
Labs are created to be a practical application of the theory content learned and are therefore more beneficial for students if they have watched or read weekly resources prior to lab. While this was communicated to students, many still came unprepared.
Recommendation
Explicitly indicate in Moodle the specific resources that students should complete prior to attending each lab.
Action Taken
Nil.
Source: Medical imaging team and unit coordinator
Feedback
The lab activities provide an opportunity for a more authentic assessment item.
Recommendation
Review the assessment strategy 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.

This unit links to the following Professional Capabilities for Medical Radiation Practitioners as detailed by the Medical Radiation Practice Board of Australia (effective March 2020):
