Medical Imaging Systems - ELEC316

The aim of this unit is to provide a basic understanding of various medical imaging systems such as X-ray, CT, Ultrasound, PET, SPECT and MRI. The unit consists of five modules. Each module covers the basic working principles, underlying physics, system hardware and image reconstruction principles, for each specific imaging modality. In the first module, an overview of X-ray and CT imaging systems will be provided. This will be followed by a second module on nuclear medicine which consists of PET and SPECT systems. Module three will include ultrasound system explaining about systems based on Pulse Echo and Doppler Effect. Module four will explain about MRI where basic MR physics, imaging principles, and image reconstruction algorithms will be explained followed by introduction of system designs at various magnetic fields. In module five, various other imaging systems such as bio-luminescence and MSOT will be introduced. The theory of medical imaging systems will be tested in practice through tutorials and practical sessions which involve the modelling and simulation exercises on multi-physics design aspects of medical imaging systems. These exercises will be done using a commercial software COMSOL Multiphysics 5.3 and MATLAB. Besides, there will be some hands on experimentation exercises for MRI sub-parts, and optical CT.
