Module summary

This module will describe the principles and role of computer image processing and analysis in medical imaging. It covers both the underlying theory and provides students with practical experience of these techniques applied to medical images using a computer image processing package.

Objectives

To provide an understanding of the principles of medical image processing and give practical experience realising them using an image processing package.
To provide an appreciation of how medical image analysis contributes to current practice and research in medical imaging.

Learning outcomes
On completion of this module, students should be able to:

1. demonstrate knowledge and understanding of the main categories of Image Processing operation and be able to recognise and describe individual image processing
2. understand the principles of key concepts used in medical image processing; demonstrate the ability to evaluate and select image processing operations for a particular task;
3. critically evaluate alternative methods for performing a particular medical image analysis task;
4. demonstrate the ability to develop an image processing algorithm which combines a range of image processing operations to solve a given medical image task;
5. employ good practice when undertaking medical image work with regard to planning, execution and data protection;
6. recognise and understand how (and why) image processing techniques can be applied across all medical imaging modalties;
7. critically analyse recent developments related to medical imaging or visualisation;
8. identify and understand how artifacts on diagnostic images can alter the viewers' perception and the problems associated.

Skills outcomes
Ability to employ image processing and analysis techniques appropriate to medical imaging, having both an understanding of the theoretical background and practical experience.
