Review & Consolidation tutorial
Online test 2 Due: Review/Exam Week Friday (14 Oct 2022) 11:15 am AEST
MEDI12005: Science & Instrumentation 2 is a condensed unit that runs from Weeks 6 -13, as most of you are on placement during the first half of term. Being a six credit unit, you are expected to commit 150 hours to the unit, which equates to about 18.5 hours per week over the 8 weeks. A suggested breakdown of your time would be:
- 4 hours for watching recorded lectures
- 3.5 hours for completing assigned reading
- 2 hours for completing other posted learning activities
- 3 hours for creating study notes to meet weekly learning goals using lectures and readings
- 2 hours for working on posted tutorial questions in preparation for tutorial
- 1 hour for participation in tutorial
- 3 hours for preparation and/or revision for online tests
There will be a two hour lab held between Weeks 7 and 8 on the topic "Controlling radiographic image appearances". You are to attend only one of the lab sessions scheduled in either Week 7 or Week 8. Take note that you are to adhere to the Course Dress Code when using the Medical Imaging simulation labs and a zero-tolerance policy will be followed.
The material covered in Weeks 9-12 is foundation knowledge for MEDI12006 Imaging Procedures 2.
The first online test will be held in Week 9 and the End of term online test will be held in Week 13. To help you prepare for the two assessments, it is suggested that you spend at least a total of 30 hours for revision (i.e. 10 hours for the first test and 20 hours for the second test).
There will be weekly tutorials held from Weeks 6 - 12. A review and consolidation tutorial will be held in Week 13. Take note that these tutorials are interactive sessions where your participation enables you to check your understanding of and your ability to apply the weekly concepts and for you to build your skills in responding to test questions. Your regular and active participation strongly supports your success in the unit.
1 Online Test
You will complete an online test on Wednesday 14 September 2022 in Week 9. This test will be available from 9:00am to 10:45am AEST. The test is a timed test that will begin once you've opened it, and will be for a duration of 90 minutes, closing automatically when the 90 minutes is up (or at the 10:45am closing time, whichever comes first). Any unanswered questions or unsaved responses will receive a mark of zero. Take note that you have until 9:15am AEST to log on to the test to utilise the full 90 minutes.
This test contributes 40% towards your final unit grade. The aim of the test is for you to demonstrate your ability to apply the concepts and use the terminology covered from Weeks 6-8 (Modules 1 -3) of the unit. All questions will be based on the posted weekly learning goals. The question tasks will be of similar type to those discussed in weekly tutorials and will require you to apply your knowledge and understanding to a given scenario. These tasks may include analysis of diagrams and photographs to explain and discuss concepts. There will be a mixture of problem solving and application of concepts type questions.
This is an open book test. It means that during the test you may access your study notes, textbook, the unit Moodle site and/or any website. The standards of academic integrity still apply. All responses must be your own work. Colluding with other students on non-group work is considered academic misconduct. Just as for written assignments, you must acknowledge intellectual content in your answers that is not your own work. Basic statements of facts are considered 'common knowledge' in the context of this unit so they do not need to be cited. However, if you copy any explanation content word-for-word from ANY source, you must put that content in quotation marks and formally cite your source. Although this is an open book test, the expectation is that you will be familiar with the unit content and concepts. You should not assume you will have time to look up the answer to every question.
As per the Assessment Procedures, this test must be written at the timetabled date and time. There is no opportunity to apply a late penalty. In the absence of an approved extension, you cannot complete this assessment at a later time and you will receive a mark of zero for the assessment if you have not submitted it by the scheduled date and time. If you start the test late, you will still be required to submit at the stated closing time.
Week 9 Wednesday (14 Sept 2022) 10:45 am AEST
Week 11 Wednesday (28 Sept 2022)
Question responses will be scored on the following criteria:
- correct use of terminology
- correct selection and application of core concepts to the specific content of the question
- clarity, correctness, relevance and completeness of the response in addressing the question that was asked
- critical thinking
The number of marks for each question are allocated based on the depth and breadth of the required response, and will be indicated on the online test.
- Relate the main sub-components of the x-ray generator to the overall generator operation and the controlled production of radiation
- Outline the use of automatic exposure timing devices in controlling the duration and quantity of a given exposure and the safe operation of a digital radiographic unit
- Apply concepts of exposure index, pre-processing and correction, histogram analysis and post-processing to control radiographic image appearances
- Communication
- Problem Solving
- Information Technology Competence
2 Online Test

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.
