Validation of a stereo camera system to quantify brain deformation due to breathing and pulsatility

Purpose: A new stereo vision system is presented to quantify brain shift and pulsatility in open‐skull neurosurgeries. Methods: The system is endowed with hardware and software synchronous image acquisition with timestamp embedding in the captured images, a brain surface oriented feature detection,...
