MRTY2107: Imaging Technology 2

Semester 2 Early, 2020 [Normal day] - Cumberland, Sydney

This unit of study extends students' knowledge of direct and computed radiography systems. Imaging principles of fluoroscopy, computed tomography, dental imaging and magnetic resonance imaging will be investigated with particular reference to equipment, safety, dosimetry and artefacts. Students will be expected to demonstrate an understanding of image processing techniques commonly applied in sectional imaging modalities. Projection radiography will be evaluated from a historical perspective, including changes in exposure factors resulting from newer technologies.

For more information see guide to grades.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

Attendance: 

Attendance at online lectures and close attention to the practical is recommended. Discussions in and during class are often useful and are not well recorded by the automated recording systems online, so attendance is a fuller learning experience and I strongly recommend you attend as many live online presentations as possible. The review lecture is particularly important as it puts the whole unit into context.

The unit takes an active learning approach; there will be activities in class, pre-reading before class and discussion during it. The practical demonstration is designed to integrate with and complement lectures, so the learning experience comes from the combination of these activities. As this is a 6 Credit Point course it is generally assumed to require about 6 hours of work on the unit per week.

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

This section outlines changes made to this unit following staff and student reviews.

Thank you for your feedback. Your constructive and positive comments are much appreciated. A report showing the response rate and distribution of responses for each item is available below. The feedback was reviewed and discussed at several meetings with colleagues. There were a few themes which were identified as requiring change. It seems that some students did not understand the aims and objectives of this Unit of Study. A clearer motivation for the delivery of the various topics covered in the Unit of Study will be done to ensure that students fully understand the need to integrate knowledge acquired during the course overall. A three prong approach was developed to address some of the suggested changes. Firstly: The number of lecturers will be reduced so that a more consistent style and presentation coherence should be achieved. Secondly: The number of tutorials will be increased so as to ensure engagement with the study material. Finally: The assessment of the students will be done more regularly during the semester to ensure that there is less pressure on the students at the end of the semester. Thank you again for your positive participation, and I wish you all well in the future. Will
