MEDS20009 - Science and Instrumentation of Ultrasound

General Information

Unit Synopsis

This unit aims to develop knowledge and understanding of the science and instrumentation of clinical ultrasound to enable you to practically produce and optimise sonographic images to support clinical decision making. The unit emphasis will be on image optimisation, safety and quality assurance. This unit will form the foundation from which you will build image acquisition, recognition and assessment skills as part of the Graduate Certificate in Clinical Ultrasound.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability.

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 Postgraduate 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 Quiz(zes) 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: Student email.
Feedback
The alteration of the physics written assessment due to covid-19 where images were provided to students to discuss helped my learning.
Recommendation
Consider providing assessment tasks that are not related to image acquisition by students in residential schools but rather allow students to comment on clinical images. This may include discussion of how images could be optimised or how artifacts are demonstrated or can be overcome.
Action Taken
In T1, 2021, assessment tasks involved online quizzes and tests. This was altered from previous unit offerings (2020 and prior) where students were required to complete and submit written assessments and an online test at the end of the term. Assessments provided throughout the term (rather than just at the end of term) were designed to allow a deeper understanding of physics concepts related to sonographic imaging to be developed over the term duration.
Source: Student email.
Feedback
The feedback provided on assessment tasks was helpful.
Recommendation
Continue to provide in-depth feedback on written assessments to enhance student understanding and the practical applications of physics principles.
Action Taken
Feedback on assessment tasks was provided in written form but also provided in verbal form in tutorial discussions. By using quizzes throughout the term, this allowed students to check on their content knowledge and understanding throughout the term rather than just at the end of term.
Source: Student email.
Feedback
It is expensive having to pay for travel and accommodation for one little alone two separate residential schools.
Recommendation
Consider either condensing the residential school into a single residential school, or running a virtual residential school, to take into consideration the costs of travel and accommodation for students.
Action Taken
The residential school/s were no longer offered in this unit in T1, 2021 based on previous student feedback regarding the costs involved with travel and accommodation for residential school attendance. The unit was re-designed for online delivery. Activities were embedded into tutorials offered regularly throughout the term.
Source: Moodle unit site 'Have your say' student feedback.
Feedback
Students suggested that a practical component would enhance their understanding, particularly for students that have not used an ultrasound unit before.
Recommendation
Consider developing and adding videos or delivering tutorials with a tutor in front of an ultrasound unit demonstrating the use of the ultrasound unit in real time, and how alteration of controls of the ultrasound unit (such as gain, depth, focus, colour Doppler, pulsed wave Doppler etc) can affect the subsequent real time ultrasound imaging.
Action Taken
Nil.

Feedback
Students comment that unit is content heavy, but felt they were well guided towards assessments.
Recommendation
Continue to use and further develop authentic test questions which relate to the practical use of ultrasound for clinical scenarios. Continue to guide and support students in regular tutorials, providing questions and model answers, to ensure they develop a conceptual understanding of the physics related to clinical sonographic imaging.
Action Taken
Nil.
Unit learning Outcomes

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

  1. Apply the knowledge of physical principles of diagnostic ultrasound to the acquisition and optimisation of sonographic imaging
  2. Interpret the cause of imaging artifacts and use problem solving skills to reduce and overcome these artifacts on real time sonographic imaging using all modes of ultrasound
  3. Discuss the bioeffects and safety issues associated with diagnostic medical sonography and how these can be managed.
