Wide-field fast-scanning photoacoustic microscopy of brain functions in action


We have developed fast functional photoacoustic microscopy for 3D high-resolution high-speed imaging of the mouse brain. In particular, a novel single-wavelength pulse-width-based method can image blood oxygenation with capillary-level resolution at 100 kHz frame rate.
