(a) Schematic of the ms-TRFS instrumentation used for imaging purposes. A single fiber is used for excitation and autofluorescence collection. PL: Pulsed Laser, DAQ: Data Acquisition, PMT: Photomultiplier. (b) Imaging setup. A hand-guided scan was performed for each specimen. An aiming beam is integrated into the optical path and serves as a marker to overlay fluorescence data on the video where the measurement was taken. (c) FLIm system and computers assembled on a cart equipped with two screens that was used to image the breast specimens.
