Assessment Overview
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.

1 Written Assessment
Task Description
This written assessment has thirteen (13) possible questions. You will choose five (5) to answer. Your choice must include at least one (1) question that requires images from your physics practical labs. Subjects covered may be image quality, artifacts, image optimisation, instrumentation or the physics of ultrasound. Images from your physics practical labs may be shared within your lab group. Those images will not be overtly judged on their quality (i.e. containing undesirable artifacts or poorly optimised), but it is assumed that together with your tutor, you shall identify and collect images of reasonable quality. Formulae, flow-charts, diagrams and images may be used to illustrate your answer, even when not specifically asked for.
Word Count is 2000 +/- 10% (e.g.200) words, excluding tables, charts, diagrams and reference list
Background
As a sonographer, you must understand the physical principles which create the images you are acquiring and the artifacts observed during the sonographic imaging process. This helps you improve your images and may help in diagnosis e.g. the posterior shadow from a kidney calculus or the posterior enhancement from a breast cyst. A sonographer must be able to use ultrasound equipment safely, and be familiar with the safety guidelines set by any governing bodies.
Referencing Style
You must use APA in-text referencing system. References for each answer must be included in a References Page at the end of the assignment. Ensure that you reference your answers using at least two (2) different sources for each question. At least one (1) reference must be a primary source for each question. The same reference source may be used for more than one individual question. Contact CQU library staff for guidance if required.
The use of Endnote TM referencing software is expected. Another document will be given for details on how to download and use Endnote TM.
Submission
Via Turnitin using MEDS12001 Moodle site.
File must be in a ‘word’ file i.e. docx. NOT PDF.
File name <your surname>_<your student number>_MEDS12001assessment
e.g. Beirne_s1234567_MEDS12001assessment
Format
You need to submit the assignment with a cover page stating your:
Name
Student number
Unit code
Campus enrolled
Group members from Physics Lab 1

2 Practical Assessment
Task Description
These labs will provide an opportunity for you to explore the physical principles of ultrasound and develop your knowledge of machine instrumentation and knobology 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 book during the lab.
The questions will be a mixture of closed procedure (fill in the gap) and very short answer. They 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. Your final written examination during Exam Week will be based on the learning in these labs as well as lecture material and textbook content.
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'
Three (3) physics labs will be held on Thursdays in weeks 3, 6 and 11.
You will be required to UPLOAD your lab booklet answers to the 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 in your own time for submission to the assessment link.
BRING a USB stick to lab to save your images
At completion of each lab session. 23:45 (AEST) Friday of the week following the practical lab.
Answers will be given and discussed at the following week's tutorial

Dictionary - non-electronic, concise, direct translation only (dictionary must not contain any notes or comments).
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.
