Roger Zemp research applies photoacoustics for 'brainspotting'

06 January 2012

Work by SPIE Member Roger Zemp (Univ. of Alberta) aimed at noninvasive examination of brain and other tissue by using light and sound is helping advance the emerging field of photoacoustics, according to a recent article in The Scientist.

Zemp's photoacoustic laser imaging technique involves sending short pulses of light into tissue to warm molecules and build an image using ultrasound sensors that detect the sound of the warmed molecules "popping."

Zemp has published more than 35 papers in the SPIE Digital Library. Several new papers on his research in photoacoustics will be presented at SPIE Photonics West 2012.
