Novel laser sources and real-time detection for in-vivo acousto-optic imaging

PDF - 237.7 kio

Imaging biological tissue with light is a great challenge for the detection of objects (e. g. tumors) at large depth
(>cm), since multiple scattering processes prevent from a conventional imaging. The combination of ultrasound
(US) and light within the medium allows to retrieve an optical information guided by the ultrasound beam,
ballistic at medical application frequencies, e.g. 6MHz. Such a strategy is called Acousto-Optic Imaging (AOI), also
called Ultrasound Optical Tomography (UOT), it is based on the acousto-optic effect (AO).
