General Information

Overview

You will be introduced to the principles of ultrasound physics and instrumentation in this unit. Quality Assurance and recognition of artefacts will also be covered. The knowledge and skills learnt from this unit are integral to all concurrent and subsequent sonography units and 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.

Assessment Grading

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%). Consult the University’s Grades and Results Policy for more details of interim results and final grades.

Term Specific Information

Students are expected to spend on average 10-12 hours of time each week in their study activities for this unit. A suggested time budget for weekly study is:

· 2- 2.5 hours for watching recorded lectures and taking notes

· 1-1.5 hours for completing assigned reading

· 0.5-1 hour for completing other posted learning activities

· 2-2.5 hours for creating study notes to meet weekly learning goals using lectures and readings

· 0.5 hour for adding week specific content to your ‘cheat sheet’

· 1-1.5 hours for applying weekly content using posted end-of-chapter questions

· 0.5 hour for working on posted tutorial questions in preparation for tutorial

· 1 hour for participation in online tutorial

· 1-2 hours for assignment preparation and/or revision for final examination

Tutorials are interactive sessions where your participation enables you to check your understanding of and your ability to apply the week’s concepts and for you to build your skills in responding to test questions. Your regular participation strongly supports your success in the unit. While online tutorials will be recorded, these recordings are not intended to replace your active participation in live sessions.

Three (3) physics labs will be held on Thursdays in weeks 3, 5 and 10.

The unit co-ordinator for MEDS12001 Term 1, 2018 is to be advised. Deborah Dahdah and Michelle Fenech will be assisting with the unit co-ordination and conducting some lectures and tutorials.

The best mode of contact is by email: d.dahdah@cqu.edu.au. Please use email whenever possible.

Deborah’s CQUniversity Australia phone number is 02 9324 5070. 

Michelle’s CQUniversity Australia phone number is (07) 3295 1180.

The online tutorials are an opportunity to ask questions, gain feedback and join in discussions concerning theoretical concepts and assessment tasks. These will be recorded for those unable to attend and posted on the unit Moodle page.

Access to the internet is required to undertake this unit, as unit materials, tutorials and updates will be provided via Moodle, Zoom and email. It is important to regularly check your student email as updates about the unit will be sent from the unit co-ordinator via email.

Zoom Tutorials will be held weekly on Monday. These will be recorded for those unable to attend and posted on the unit Moodle page.


Assessment Tasks

1 Written Assessment

Assessment Title
Written Assesssment

Task Description

There will be five (5) short-answer questions worth 20 marks each.

The questions will be based on the Laboratory Sessions (including the images obtained during Labs 1 and 2) and lecture and tutorial material up to the submission date.

The maximum word count is 1000 +/- 10%, excluding tables, charts, diagrams and reference list.

As a sonographer, it is imperative you understand the physical principles which create the images you acquire and the potential artifacts incurred during the sonographic imaging process. This understanding will help you to improve your image acquisition and quality and will help in the diagnostic process. A sonographer must be able to use ultrasound equipment safely and be familiar with the safety guidelines set by any governing bodies.


Assessment Due Date

Week 7 Monday (23 Apr 2018) 2:00 pm AEST


Return Date to Students

Week 9 Monday (7 May 2018)

General feedback will be provided up to 2 weeks after submission.

2 Practical Assessment

Assessment Title
Practical Laboratory Sessions and Lab Manual completion

Task Description

In small groups (3-4 people), you will be required to collaboratively perform tasks during the practical Laboratory sessions and obtain ultrasound images that will assist to answer set questions, and then individually submit the completed Laboratory manual.

These labs will provide an opportunity for you to explore the physical principles of ultrasound and develop your knowledge of machine instrumentation and controls under the guidance of your tutor.

During the labs you will be required to take images, and observe the effect of changing machine parameters on the resultant image.

You will be required to complete questions in your lab manual during the lab session. The questions are designed to help you understand the physical properties of ultrasound and how that knowledge is used to inform the practical production of diagnostic medical images.

Students may work in teams to acquire images. Image sharing within your lab group is permitted.

Please note the following excerpt from the University Assessment of Coursework Procedures: '...students who fail a single assessment task in a pass-fail course, or who fail a pass-fail component of a graded course will be deemed to have failed that course'.

You will be required to UPLOAD your lab manual answers to the unit Moodle page via the link provided in the assessment block. Non-attendance at a lab for any reason will require you to complete the learning and practical exercises, with consideration to lab availability, for submission to the assessment link.

Bring a USB stick to lab to save your images.

It is a highly recommended component of the unit to attend the Laboratory practical sessions in order to meet the Learning Outcomes.

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.
