Fig. 5From: Towards the use of diffuse reflectance spectroscopy for real-time in vivo detection of breast cancer during surgeryClassification of continuous data. In the left part of the image, US images taken along the needle trajectory at ‘normal’ and ‘tumor’. The middle of the image includes the outcomes of the classification algorithms, where the x-axis is the measurement number (≠ distance) and the y-axis is the probability of a measurement being normal (> 0.5) or tumor (< 0.5). The green and red arrows indicate the locations where the needle was kept still. The histopathology of the part of the biopsy specimen that was in contact with the needle is displayed in the right sideBack to article page
