Abstract: A noncontact, multi-wavelength time-resolved laser speckle contrast imaging (MTR-LSCI) technique provides for continuous, fast and high-resolution 2D mapping of tissue blood flow (BF) and tissue blood oxygen saturation (StO2) at different depths of target tissue. MTR-LSCI illuminates the tissue with picosecond-pulsed, coherent, widefield light at least at two different wavelengths in the near-infrared range (600-1100 nm) and synchronizes a high-resolution, gated single-photon avalanche diode (SPAD) camera to capture BF and StO2 maps at different depths of target tissue, wherein the imaging depth depends on light propagation inside a tissue volume, captured by the time-gated camera. The reconstruction of BF and StO2 maps can be dramatically expedited by incorporating highly parallelized computation and convolution functions. The performance of MTR-LSCI was evaluated using head-simulating phantoms with known properties and in-vivo rodents with varied hemodynamic challenges to the brain.
