MEDS12001 - Physics of Ultrasound

General Information

Unit Synopsis

The principles of ultrasound physics and instrumentation are introduced in this course. Quality Assurance and recognition of artefacts are also covered. Knowledge and skills learnt from this course are integral to all Doppler subsequent sonography courses and the foundation from which the students will build their image acquisition, recognition and assessment skills. Students will apply knowledge and skills of physics principles in the laboratory setting using ultrasound equipment.

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 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 Quiz(zes) 10%
2. Written Assessment 30%
3. Examination 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: Have Your Say
Feedback
Students commented that a lot of resources were provided to enhance their understanding of physics concepts.
Recommendation
Continue to provide support through a comprehensive range of resources for students to enhance their understanding of various concepts.
Action Taken
A comprehensive and diverse range of resources and additional recorded lectures were provided for students as per recommendations.
Source: Have Your Say
Feedback
Students reported that they benefited from the online virtual labs in place of the on campus labs. This enabled them to watch lab tasks several times in order to complete the lab manual assessment successfully.
Recommendation
The virtual labs videos will remain as a resource for revision prior to the unit's relevant assessments.
Action Taken
This year students had access to their campuses when the physics labs were offered. There was no need to use the virtual lab videos from 2020, as students could attend the labs in person to perform the assigned tasks. This resource will remain in the unit as a useful revision tool prior to the end of the term online test. The virtual labs videos will remain as a resource for revision prior to the unit's relevant assessments.

Feedback
Students commented that their e-mails and queries were answered in record time, which they felt was very helpful when they couldn't progress further in their revision until their question was addressed.
Recommendation
Continue to provide timely response to all student e-mails and questions on the Q&A forum.
Action Taken
I continued to provide prompt response to students' e-mails and provide timely answers to their questions on the Q&A forum.
Source: Have Your Say
Feedback
Students commented that the Lab Manual was a really good assessment as it made them think and allowed them time in the labs to really understand the theory.
Recommendation
Ensure the lab manual is available from beginning of the term, so students have the opportunity to complete the pre-lab readings and study the expected tasks prior to attending the labs.
Action Taken
Nil.
Source: Have Your Say
Feedback
Students noted that the expectations and requirements for the unit assessments were very clearly explained.
Recommendation
Continue to explain the criteria for each assessment clearly and ensure there is transparency in unit's expectation and requirements as per previous years.
Action Taken
Nil.
Source: Have Your Say
Feedback
Students commented that they wished for the first physics lab to be offered earlier in the term, ideally before the first scanning skills lab, so they could get familiarised with the equipment prior to their first scanning skills lab.
Recommendation
Ensure that the first physics lab is offered before the first scanning skills lab. The required change in the lab timetable for 2022 has already been requested to implement this change.
Action Taken
Nil.
Unit learning Outcomes

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

  1. Explain the fundamental principles of sonographic imaging.
  2. Describe the basic principles of sound waves and their interactions with matter.
  3. Describe the properties and capabilities of diagnostic ultrasound transducers and how they relate to image resolution.
  4. Discuss the key components within diagnostic ultrasound instrumentation for echo signal processing related to image formation, quality, storage and display.
  5. Discuss advanced ultrasound imaging techniques.
  6. Relate the principles of fluid and hemodynamics in the human body to the physical principles of the Doppler effect.
