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: SUTE student comments
Feedback
The unit is simultaneously delivered to CG91 (Sonography) and CV69 (Echocardiography) students. Some CV69 students feel the unit content needs to be more relatable to their situation.
Recommendation
Consider a cross-discipline approach whereby CV69 staff are more involved in content creation and/or delivery of the unit.
Action Taken
The unit coordinator and CV69 staff worked more closely to ensure accurate and relevant cardiac specific content. CV69 staff were present at many tutorials and were available to answer QandA forum questions. CV69 students completed a separate end of term quiz formulated to be more authentic to their discipline. Some questions in the CV69 specific lab manual were rewritten to make them more applicable to cardiovascular principles.
Source: SUTE student comments
Feedback
Some students felt that the final lab session was too rushed and they needed increased tutor support as a consequence.
Recommendation
Consider modifying the content or structure of the lab sessions to provide an improved learning experience.
Action Taken
The entire lab manual was rewritten to make it more succinct and logical. There was an improvement in the timing for the final lab, but it was still too rushed and further amendments have been noted for next year.
Source: SUTE student comments
Feedback
Some students found that lectures were too long and complicated, which created some confusion with new concepts.
Recommendation
Refresh lectures with a focus on providing clear and concise explanations of concepts.
Action Taken
Lectures by the former unit coordinator were too long and complicated. Most of these lectures have been replaced, but some of the aged material will need to be updated prior to 2024. Feedback suggests that the weekly tutorials supported student comprehension of lecture content, as concepts were presented from a different perspective.
Source: SUTE Teacher Evaluations
Feedback
Some students found that it was difficult to remain engaged during tutorials, as Physics is quite dense.
Recommendation
Construct online quizzes such as Kahoot during tutorials to encourage interaction and engagement.
Action Taken
Nil.

Feedback
Some of the older lectures have poor audio quality and are blurry when using different platforms.
Recommendation
Replace older lectures as the audio tends to distort when the volume is too high.
Action Taken
Nil.

Feedback
The final Lab session is too rushed.
Recommendation
Some content from Lab 3 can be transferred to Lab 2.
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.
  7. Discuss the application and instrumentation of Doppler imaging techniques.
  8. Analyse the causes of various types of image artefacts and the associated optimization techniques to reduce artefacts.
