Module aims

Module will give an overview of the physics, methods and equipment employed in modern medical physics. The basic interaction processes of particles with matter are outlined, including the interaction of ionising and non-ionising radiation with biological systems. Radiotherapy methods including brachytherapy, molecular therapy, external beam therapy (neutron, photon, proton, ion, anti-proton) and the effects of radiation at the cellular level are presented. The course will outline the latest development in intensity-modulated mixed-beam radiotherapy. Methods to measure and monitor radiation are discussed. Methods and signal processing employed for high-field/squid MR imaging, PET imaging, SPECT imaging, and ultrasound will be presented. Methods of production (reactor based, cyclotron based, isotope generators) and use of various radiopharmaceuticals will be discussed. Practical use of various detection techniques and methods will be demonstrated in laboratory sessions. The course will include a significant component based on computer simulation. Links to industry will also be explored.

Module learning outcomes

At the completion of the course students will have acquired the skills to:

  1. Understand the detailed interactions of radiation with matter and biological tissue. Apply this knowledge to compare and contrast a range of radiotherapy techniques

  2. Describe the detectors and methods used to monitor radiation dose and biological damage from radiation

  3. Explain MRI and PET imaging, how the compare and how they are realised in practical devices

  4. Demonstrate the use of computer simulations to investigate aspects of medical physics, detector design, and treatment design

  5. Synthesise, present, and discuss the applications of physics techniques in a specific medical example case

Module feedback

'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme. We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments.

A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback. This can be found at:

https://www.york.ac.uk/students/studying/assessment-and-examination/guide-to-assessment/

The School of Physics, Engineering & Technology aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme. In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work. Students are provided with their examination results within 25 working days of the end of any given examination period. The School will also endeavour to return all coursework feedback within 25 working days of the submission deadline. The School would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback. The School will endeavour to keep such delays to a minimum. Please note that any marks released are subject to ratification by the Board of Examiners and Senate. Meetings at the start/end of each semester provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date.

Our policy on how you receive feedback for formative and summative purposes is contained in our Physics at York Taught Student Handbook.
