Paper Abstract
The determination of tumor margins during surgical resection remains a challenging task. A complete removal of
malignant tissue and conservation of healthy tissue is important for the preservation of organ function, patient
satisfaction, and quality of life. Visual inspection and palpation is not sufficient for discriminating between malignant
and normal tissue types. Hyperspectral imaging (HSI) technology has the potential to noninvasively delineate surgical
tumor margin and can be used as an intra-operative visual aid tool. Since histological images provide the ground truth of
cancer margins, it is necessary to warp the cancer regions in ex vivo histological images back to in vivo hyperspectral
images in order to validate the tumor margins detected by HSI and to optimize the imaging parameters. In this paper,
principal component analysis (PCA) is utilized to extract the principle component bands of the HSI images, which is
then used to register HSI images with the corresponding histological image. Affine registration is chosen to model the
global transformation. A B-spline free form deformation (FFD) method is used to model the local non-rigid deformation.
Registration experiment was performed on animal hyperspectral and histological images. Experimental results from
animals demonstrated the feasibility of the hyperspectral imaging method for cancer margin detection.
