MEDI12002 - Science and Instrumentation 1
Term 1 - 2017


All details in this unit profile for MEDI12002 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.

Overview

This is the first of three units where knowledge is developed and built on in each subsequent unit, and applied in the clinical environment. You will be introduced to the equipment, instruments and science necessary to produce a digital radiographic image. You will learn about technical factor selection, their impact on the image and the acquisition, manipulation and processing of the final image. All material learnt in this unit is reinforced in a simulated setting. A digital radiological laboratory and imaging workstations linked to PACS will allow for experiential learning.

Assessment Overview

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

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 Source Recommendation
Assessment feedback. Coordinator self-reflection Have your say evaluation Since students work in small groups to acquire the data for the portfolio assessment, it is recommended to have the final work submitted as a group work instead of individual submission. This will reduce the time spent marking the assessments and enable a more timely feedback to be provided.
Emphasis on definition of key terminologies to promote consistent usage within the course and in other core courses in the program. Coordinator self-reflection Have your say evaluation Key terms were discussed during lectures, labs and tutorials but some of the terms were either confused or used interchangeably by students resulting in deviation from the context. Including a glossary list in the course Moodle site will help deal with this issue.
Use of study guides for tutorials. Coordinator self-reflection Have your say evaluation Provide study guides as a self-study tool for students to test their understanding of the course content. Include more interactive activities for tutorial sessions.
On successful completion of this unit, you will be able to:
  1. Perform radiographic imaging in a safe and technically correct manner in a simulated PACS-integrated digital radiographic environment.
  2. Outline the construction and operation of various digital radiographic image receptors and processing systems.
  3. Detail the processes of image acquisition, processing and display for digital radiography.
  4. Evaluate the technical aspects of radiographic image appearances.
  5. Control the technical aspects of radiographic image appearances.

This unit supports your ability to meet the following components of the Medical Radiation Practice Board of Australia's Professional Capabilities for Medical Radiation Practice:

Domain 4:

1. Implement safe radiation practice appropriate to their division of registration.

5. Safely manage radiation and radioactivity in the environment.

Domain 5:

2. Apply principles of medical radiation physics and instrumentation.

Domain 5A:

1. Implement and evaluate general radiography examinations for a range of patient/client presentations and complexities.

Note:

Both textbooks are required for all three of the Science & Instrumentation courses plus MEDI12007 Dose and Image Optimisation and MEDI12001 Radiation Science across Years 2 and 3 of the program. Students should already have purchased these books for MEDI12001.

Students may opt to use either the 10th or the 11th edition of Radiologic Science for Technologists. Students may opt to purchase the e-book version of The Essential Physics of Medical Imaging (ISBN 9781469871738) rather than the hard copy.

You are required to wear your Medical Imaging lab/clinical shirt for all practical lab sessions.

1 In-class Test(s)

Assessment Title In-Class Test 1
Task Description

You will write an in-class test to demonstrate your ability to apply the concepts and use the terminology from all weeks of study, with Weeks 1 - 5 of the unit. All questions will be based on the posted weekly learning goals. Question tasks will be of the same types that you will practice in weekly tutorials. These tasks may include analysis of projected diagrams, photographs and/or radiographs, creation of line diagrams to illustrate concepts, explanations and discussions.

This test is a closed-book assessment of 90 minutes duration. You will have a five minute perusal time prior to the allotted writing time. You will write the test under examinations conditions as detailed in the Assessment Procedures. You will submit your test paper and rough paper at the end of the test period.

This test must be written at the timetabled date and time. As per the Assessment Procedures, this task is to be completed during a defined period. There is no opportunity to apply a late penalty. If you arrive late, you may enter the test room up to 30 minutes after the start of the test; however, you will still be required to submit your test at the standard test end time. You will not be allowed entry more than 30 minutes after the test starts. In the absence of an approved extension, you cannot complete this assessment at a later time, and you will receive a mark of zero for the assessment if you have not completed it by the scheduled date and time.
