摘要：
Present embodiments are directed to a system and method capable of modulating light at a modulation frequency, wherein the modulation frequency is somewhere above about 50 MHz and below about 3 GHz, to generate photon density waves in a medium, detecting relative amplitude changes and phase shifts in the photon density waves, and detecting and graphically indicating a physiologic value related to scattering particles in the medium based on the phase shifts.
