Popis:	This paper demonstrates the performance of CMOS detection methods and the potential for custom made CMOS sensors to be used in ultrasound modulated optical tomography. The sensors developed within our group have been characterized and results of the typical performance levels are shown. A model of ultrasound modulated light propagation from a scattering medium, through a random phase screen and onto the detector is shown. Experimental results in different detection configuration validate the modeling approach. Finally a comparison between a single point detector and an imaging array demonstrate the value of array detection in ultrasound modulated optical tomography.
