Congratulations to Emeritus Professor David H Evans on his Honorary Fellow Award.

The American Institute of Ultrasound in Medicine (AIUM) has announced the recipients of awards who will be honoured at its annual convention in Phoenix Arizona this weekend.

One of two recipients of the Honorary Fellow Award is David H Evans, Emeritus Professor of Medical Physics in our Department of Cardiovascular Sciences. With this award, the AIUM is recognising “his promotion of ultrasound in medicine across the globe” which includes co-authorship of two definitive books: Doppler ultrasound: Physics, Instrumentation and Clinical Applications (1989) and Doppler ultrasound: Physics, Instrumentation and Signal Processing (2000).

Doppler ultrasound is a technique that can be used to detect blood clots. An ultrasound device passing over the skin near a blood vessel detects reflections from blood cells. If the blood vessel is clear, the cells will be moving and a Doppler effect will be present (that is, the reflections will be different depending on whether the cells are moving towards the detector or away, just like an ambulance siren changes pitch as it passes you). Where a vessel is blocked or constricted, the Doppler ultrasound device can detect non-movement of the blood cells. Blood clots, of course, can lead to conditions such as pulmonary embolism, deep vein thrombosis and stroke.

Professor Evans has held numerous responsible positions within the medical ultrasound world including President of the British Medical Ultrasound Society, President of the European Federation of Societies for Ultrasound in Medicine and Biology and Honorary Secretary of the World Federation for Ultrasound in Medicine and Biology.
