MEDS12001 - Physics of Ultrasound

General Information

Unit Synopsis

You will be introduced to the principles of ultrasound physics and instrumentation in this unit.Ultrasound safety, quality assurance and recognition of artifacts will also be covered. The knowledge and skills learnt from this unit are integral to all concurrent and subsequent sonography and echocardiography units and forms the foundation from which you will build your image acquisition, recognition and assessment skills. You will apply your knowledge and skills of physics principles in the laboratory setting using ultrasound equipment.

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. Practical Assessment 0%
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 unit evaluation
Feedback
Student appreciated timely return of the assessment grades and feedback.
Recommendation
Continue to provide timely detailed feedback via e-mail, Q&A, News Forum and Zoom tutorials.
Action Taken
The UC continued to provide timely detailed feedback via e-mail, Q&A, News Forum and Zoom tutorials.
Source: Have your say unit evaluation
Feedback
Students benefited a lot from lectures which were newly prepared and aligned with the new physics textbook. They found the content well covered and the topics explained very clearly.
Recommendation
Continue using prescribed textbook and align lectures with the textbook.
Action Taken
Lectures delivered this year were of high standards and students were happy with the contents covered in lectures.
Source: Have your say unit evaluation
Feedback
Hands on lab practicals assisted students' learning
Recommendation
The format of labs will continue but the content will be aligned with the lectures covered. The lab manuals will be provided to students in advance.
Action Taken
The labs were delivered with the recommended format. This year the lab manual and pre-lab reading requirements were available to students from 2 week prior to start of the term.
Source: Have your say unit evaluation
Feedback
Students would like an increased word count for the assessment task and a clearer marking rubric.
Recommendation
The assessment task and word limit will be revised. The marking rubric will be designed to clarify the depth of answers expected for each question. A zoom tutorial to explain in detail the requirements of the assessment will be delivered before the deadline for submission.
Action Taken
The assessment item for this unit is now changed to an online test.
Source: Have your say unit evaluation
Feedback
Students would like longer time allocated to the final exam.
Recommendation
The allocated exam time and the exam questions will be reviewed to ensure sufficient time is allocated to the exam.
Action Taken
The allocated exam time was increased form 2 hours in 2018 to 3 hours in 2019.
Source: Have your say unit evaluation
Feedback
Some students found the revised contents for this unit at a higher level than expected.
Recommendation
Introduction of a higher academic rigor in 2018, was designed to benefit the students' understanding of future units in this course. A comprehensive program of teaching at a higher standard in this unit was to reflect the requirements of the ASAR. Students' feedback and results will continue to be monitored as well as the success rates in other units for which this unit is a pre-requisite.
Action Taken
Student's comments this year reflected their satisfaction with the standard of lectures. They found the assessments straight forward and the expectations clearly defined.
Source: Have your say
Feedback
Students found that the ultrasound physics labs were a fantastic way to learn about this unit in a hands on, practical way.They, however, wished the labs started earlier in the term and extended slightly in duration.
Recommendation
The lab schedules will be reviewed.
Action Taken

Feedback
Students commented that the weekly summary study notes allowed them to revise easily and concentrate on the main concepts they needed to learn.
Recommendation
Will continue to provide weekly study notes to keep the students focused on the main concepts of each topic.
Action Taken

Source: Have your say
Feedback
The sample past exam questions and provided answers throughout the term were commented on as being the most useful learning tool by some of the students
Recommendation
Will continue to provide example past exam questions in weekly contents.
Action Taken

Source: Have your say
Feedback
Students liked the two revision weeks incorporated into the unit schedule as it allowed them to revise for the online test and for the final examination.
Recommendation
Will continue the same format of weekly contents to include revision weeks in week 6 and 12 to allow students concentrate on their assessment tasks.
Action Taken

Feedback
The online test as mid term assessment was well received as it provided feedback on students' performance half way through the term.
Recommendation
Will continue with this mid-term assessment.
Action Taken

Feedback
Echocardiography students had difficulty contextualising some of the physics to their own profession.
Recommendation
Will include more echocardiography related examples in lectures. Will continue with echo specific lab manuals as this year.
