General Information

Overview

This unit aims to develop knowledge and understanding of the science and instrumentation of clinical ultrasound to enable you to produce images to support clinical decision making. The unit emphasis will be on safety and quality assurance. You are required to attend a compulsory ultrasound skills workshop to complete this unit. In the practical workshop you will apply your knowledge of scanning technique and image optimisation. 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.

Previous Student Feedback

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 from "Have your say" feedback

Feedback

Students with no ultrasound background stated physics presented them with a lot of new concepts which was clearly explained.

Recommendation

Continue to present complex concepts using clear explanations and examples.

Feedback from "Have your say" feedback

Feedback

Students commented that the order of learning ultrasound science and instrumentation concepts were not aligned in Module 3.

Recommendation

Module 3 has been re-ordered. Further restructuring of the content will be done when this unit is divided into four short courses.

Feedback from "Have your say" feedback

Feedback

Students would like a residential school with hands on ultrasound training done earlier in the term to help them understand taught concepts.

Recommendation

Consider a non-compulsory Residential school to be run shortly after census date to give the students a hands-on experience earlier in the semester to facilitate a deeper understanding of the theoretical concepts covered in the unit.

Unit Learning Outcomes
On successful completion of this unit, you will be able to:
  1. Acquire ultrasound images of sufficient quality to support clinical decision making.
  2. Characterise and control problems in relation to imaging artifacts in ultrasound.

Assessment Tasks

1 Online Test

Assessment Title
Online Test

Task Description

Every health professional performing ultrasound is required to have a body of knowledge that is relevant to their scope of practice. Ultrasound science forms the fundamental basis upon which a clinical understanding is built. Health professionals have an ethical responsibility to carry out ultrasound accurately and safely with minimal diagnostic and health risk to the patient. To demonstrate your understanding and knowledge of this unit, you are required to complete an online test.

  • An online test will be conducted to assess your understanding of the content in this unit.
  • This is one of the two assessments (the second being combined attendance at the compulsory Residential School plus submission of Lab Manual) that must be passed to pass the unit overall.
  • The test will be online and must be accessed through the 'assessment tab' on Moodle and will comprise of 40 questions, 2 or 4 marks per question (100 marks in total).
  • Questions will be composed of multiple components, multiple choice, short answer, image interpretation, or a longer answer format.
  • As the test is online and open book, you will find it useful to have produced your own notes from the lectures.
  • Questions will be randomised from a question bank to allow tests to be different for each student.
  • Image viewing questions may be included.
  • Questions may be drawn from any content presented up to and including week 12, including but not limited to lectures, content from tutorials, the lab manual, and additional reading.
  • The assessment is to be undertaken as an individual. As with all other university assessments, colluding with other students on non-group work tasks is considered academic misconduct.
  • The test will be open for 2 hours once started and only one attempt is allowed. Please be sure to start the test at least 2 hours before the closing time so that it can be completed by the close time. At the closing time or at the completion of 2 hours you MUST save and submit the test, otherwise, all the attempted questions will be lost. Once started the test cannot be paused, stopped or re-started. Once you have completed the test, it cannot be re-taken.


Assessment Due Date

Week 11 Tuesday (4 Feb 2020) 4:00 pm AEST

The 2 hour Online test will be open from Monday 8:00am week 11 and closes Tuesday 4:00pm week 12

2 Practical Assessment

Assessment Title
Lab manual completion relating to residential school

Task Description

Ultrasound is a practical health profession, hence laboratory experience is vital to being able to develop the skills required to acquire and optimise an image.

The practical residential school day provides you with hands-on tuition so that you can manipulate both transducer and imaging parameters.

To demonstrate your understanding of image acquisition and optimisation, the laboratory manual requires you to optimise B-Mode and Doppler images and requires you to answer questions relevant to the practice of ultrasound.

  • The residential school is compulsory and must be fully attended to pass this unit.
  • All questions in the residential school lab manual must be answered and a completed lab manual submitted via the assessment tab in Moodle by Saturday 08th February by 22:00 AEST (10 pm).
  • There are questions within the lab manual which you will need to complete on the day, or in the week after.
  • The completed lab manual then needs to be uploaded and submitted via the assessment tab in Moodle.
  • This assessment is PASS/FAIL.

Academic Integrity Statement

As a CQUniversity student you are expected to act honestly in all aspects of your academic work.

Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.

When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.

Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.

As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.

What is a breach of academic integrity?

A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.

Why is academic integrity important?

A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.

Where can I get assistance?

For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
