Overview

Support for clinical imaging systems is an integral part of the Medical Physics profession. This requires an understanding of not only electronics and software, but also the fundamental physics underpinning the process of imaging. The aim of this unit is to provide you with a solid understanding of the physics behind three common medical imaging modalities: Computed Tomography, Magnetic Resonance Imaging and ultrasound imaging. These techniques complement each other both in terms of the type of radiation used (ionising radiation, radio waves and acoustic waves) and in terms of the imaging utility; therefore, this combination of techniques provides a good introduction into the diverse and rapidly developing field of medical imaging. You will learn about the interaction of these types of radiation with matter, the basic mathematical principles of image formation, the factors determining image contrast and ways to modulate contrast, and the imaging common hardware.

Learning Outcomes

On successful completion of this unit you will be able to:

  1. Demonstrate advanced knowledge and understanding of the physics and technology of x-ray radioology, magnetic resonance imaging and ultrasound.
  2. Critically and effectively apply advanced knowledge and skills in medical imaging to real world clinical problems
  3. Synthesise advanced knowledge from multiple sources to make sound judgements and to formulate strategies for best practice in diagnostic imaging medical physics.
  4. Engage and communicate effectively with peers, stakeholders and members of the clinical multi-disciplinary team.
  5. Autonomously and ethically plan and execute tasks to a high professional standard.

Content

The unit covers the three important imaging modalities of x-ray, MRI, and ultrasound with an emphasis on the physics and technology as well as the role of the clinical medical physicist. Throughout the unit you are introduced to real clinical examples of the use of the three diagnostic imaging modalities from a medical physicist's perspective.

Learning Approaches

Lectures/workshops: 2 hours / week
Practical / Experimental: 2 - 3 hours / week (4 - 5 weeks throughout the semester)

The unit uses blended learning methodology to introduce the technical content and allows you to develop your knowledge as well as the applied technical and professional skills that are required by the clinical medical physicist. The face to face element encompasses:

  • Formal lectures including interactive discussions and solutions of authentic problem solving tasks and
  • Real world learning opportunities during practicals which introduce you to medical imaging quality assurance and compliance tests, including visits to medical imaging facilities, with a strong emphasis on relating the theory to clinical practice and on the development of your practical skills. You will learn to perform some of the clinical tasks individually or as a member of a team under the supervision of experienced medical physicists.

    The online component includes teaching materials and supporting resources made available on Canvas.

Feedback on Learning and Assessment

You will be given feedback on your progress throughout the unit through the following methods:

  • Written comments on problem solving tasks and practical reports according to assessment criteria enabling you to reflect on and address any potential weaknesses in the required knowledge and skills
  • Formative feedback on online activities through online channels or in person during consultation sessions.
  • Informal peer and teacher feedback in consultation sessions and practicals.
  • Individual or group consultation on request.

Assessment

Overview

Your knowledge and skills will be assessed in a variety of ways: you will be required to write a response to a set questions, problems or issues related to magnetic resonance imaging. You will also prepare individual reports based on laboratory/practical exercises (which are designed to develep and assess your practical skills) and an end of semester written exam will assess your theoretical knowledge underpinning the practice.

Academic Integrity

Students are expected to engage in learning and assessment at QUT with honesty, transparency and fairness. Maintaining academic integrity means upholding these principles and demonstrating valuable professional capabilities based on ethical foundations.

Failure to maintain academic integrity can take many forms. It includes cheating in examinations, plagiarism, self-plagiarism, collusion, and submitting an assessment item completed by another person (e.g. contract cheating). It can also include providing your assessment to another entity, such as to a person or website.

You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.

Further details of QUT’s approach to academic integrity are outlined in the Academic integrity policy and the Student Code of Conduct. Breaching QUT’s Academic integrity policy is regarded as student misconduct and can lead to the imposition of penalties ranging from a grade reduction to exclusion from QUT.

Resources

Lecture Notes will be made available on the Canvas site.

Risk Assessment Statement

Attention will be drawn to relevant workplace health and safety issues during lectures and practicals. There are no other out of the ordinary risks associated with this unit.
