Hyperspectral imaging for tissue differentiation using neural network in parotid surgery

Introduction In parotidectomy, continuous tissue differentiation and identification of risk structures, such as the facial nerve, is essential for complication-free surgery. Thus, there is a need for a comprehensive image-based method of tissue differentiation and identification. Hyperspectral imaging (HSI) is a potential method for this purpose, as it can objectively analyze and compare spectral characteristics of individual areas.
