We have also contributed to improving the imaging speed of photoacoustic microscopy. The low imaging speed in photoacoustic imaging has been the limiting factor in dynamic studies, especially functional brain study. Using novel scanning mirrors (e.g., MEMS, polygon), we are developing fast functional photoacoustic microscopy that can achieve an imaging speed of 1 MHz (A-line) and 2 kHz (B-scan) for brain imaging.
