Biomedical Imaging Research Unit


MetaSystems VSlide slide scanner

BIRU webinar - Super-Multiplexed Imaging

Applications

  • Whole section scanning
  • Region of interest scanning including setting up a scan field (region of interest) at low magnification and then scanning the ROI at higher magnifcation/resolution.
  • Tissue microarray scanning and on the fly analysis
  • Brightfield, high resolution brightfield (using the monochrome camera) or fluorescence
