Brain blood flow monitoring surgery gets quantitative for the first time with standard camera hardware. UT Austin's SIMSI modulates laser illumination sinusoidally within each exposure to map blood flow dynamics, bypassing the high-speed sensors that blocked wide-field surgical perfusion imaging for a decade. Validated in phantoms and mouse cortex; published in PNAS.
