Lihong Wang Hot Topics Presentation: Photoacoustic tomography: ultrasonically breaking through the optical diffusion limit

Presented at SPIE Photonics Europe 2012
2 May 2012, SPIE Newsroom. DOI: 10.1117/2.3201205.04

Lihong WangWith photoacoustic techniques, Lihong Wang and his research group have been able to generate detailed information about blood oxygen content and other tissues and fluids as much as 7mm under the skin surface.

In his presentation, "Photoacoustic tomography: ultrasonically breaking through the optical diffusion limit," Wang introduces these results from his lab's work in a noninvasive multimodal biomedical 3D imaging system employing acoustical and light-based imaging.

Photoacoustic tomography (PAT) has the potential to enable multiscale systems biology and accelerate translation from microscopic laboratory discoveries to macroscopic clinical practice. PAT may also hold the key to the earliest detection of cancer by in vivo label-free quantification of hypermetabolism, the quintessential hallmark of cancer.

Lihong Wang is the Gene K. Beare Distinguished Professor of BME at Washington Univ in St Louis (USA).
