Abstract
A methods for imaging tissue using diffuse optical tomography with digital detection includes directing at the tissue a plurality of amplitude modulated optical signals from a plurality of optical signal sources illuminating the tissue at a plurality of locations; detecting a resulting plurality of attenuated optical signals exiting the tissue to obtain a plurality of analog signals containing diffuse optical tomographic information; converting the analog signals into digital signals; recovering the tomographic information from the digital signals using a digital signal processor-based detection module that performs digital detection, wherein the detection module includes a master digital signal processing subsystem and at least one slave digital signal processing subsystem that processes at least a portion of the digital signals and the master digital signal processing subsystem controls the at least one slave digital signal processing subsystem; and transmitting the recovered tomographic information in digital form to a host computer.
