From Seeing Sound, to Killing Tumours with Ultrasound

Speakers: Ian Butterworth

Ian Butterworth delves into two areas of acoustic research that divide his time:
Seeing sound
Using a laser-based approach, a technique now being developed at NPL captures videos of acoustic waves at rates of up to 20 million frames per second, allowing visualisation of sound in great detail. An overview of the technique will be presented, including high-fidelity 2D and 3D videos of acoustic fields around loudspeakers etc.
Ultrasound as a medical treatment
Medical ultrasonic imaging is a long-established and safe method of non-invasive examination. Stringent safety regulations, that NPL validates, prevent unsafe levels of ultrasound being passed into the body. Ultrasound that is too intense risks heating up the body tissue. But this effect can be harnessed, and ultrasound is growing in popularity as a method for the non-invasive killing of cancerous tissues through intense localised heating. Ian conducts work validating the heating effects of such fields, and has developed a novel low-cost visualization technique utilising the acousto-optic effect.
Talk begins at 7.30pm. Free car parking near the lecture theatre.
