    Photoacoustic Microscopy System Improves SNR and Temporal and Spatial Resolution

    Article obtained from Photonics RSS Feed.

    A superresolution localization photoacoustic microscopy (PAM) technique has been developed by a team at Pohang University of Science and Technology (POSTECH). The new system can monitor the flow of red blood cells without using a contrast absorber, enabling it to image blood vessels with exceptional resolution. Spatial resolution is improved by a factor of 2.5 in vivo, the team said.

    The new system uses a stable, commercially available galvanometer scanner with a custom-made scanning mirror. This novel hardware implementation enhances the temporal resolution of the microscope significantly while maintaining a high signal-to-noise ratio (SNR). The new system has a fast B-mode rate (500 Hz).

    The researchers used their…
