Chromophore selective multi-wavelength photoacoustic remote sensing (Conference Presentation)

Paper Abstract

To assess cancer resection margins, post-operative histological diagnosis using hematoxylin and eosin (H&E) stained slides remains the gold standard due to the lack of effective intra-operative approaches. Wait times may be up to two weeks and subsequent treatments may be necessary. Therefore, we are motivated to introduce Chromophore Selective Multi-Wavelength Photoacoustic Remote Sensing, an all-optical, non-contact, reflection-mode, label-free approach to produce H&E-like images of human tissue. This work is a step towards in-situ imaging, rapid clinical assessment of tissue, and may permit future developments as a live intraoperative surgical microscope.
