MRS400 Principles of Ultrasound and Instrumentation (8)

This subject provides an integrated presentation of the principles of ultrasound and instrumentation. It provides students with an understanding of the use of an ultrasound machine and understanding of the principles and applications of medical ultrasound. The subject covers ultrasound wave properties, ultrasound propagation and attenuation in body tissue, ultrasonic transducers and their beam properties, and the physics of blood flow (haemodynamics). The subject closely links these physical principles to the operation of modern diagnostic ultrasound instrumentation, such as two-dimensional, real-time scanning machines, M-mode scanners, and Spectral-, Colour- and Power- Doppler instrumentation. Recent advances in transducer- and imaging- technology are also discussed. Student will also gain an understanding of quality assurance with respect to ultrasound equipment, together with ultrasound bioeffects and safety considerations.
