Abstract

Mueller matrix coefficients are conventionally derived from averaged measurements of several polarimetric intensity images for each polarisation state. However, averaging large numbers of measurements is not compatible with real-time surgical applications. To overcome this limitation, we introduce a novel learning-based denoising framework aiming at recovering accurate, physically consistent and high signal-to-noise ratio (SNR) polarimetric scans from short-time noisy acquisitions. We formulate a microstructure-aware denoising diffusion network and validate against current state-of-the-art denoising techniques for real images in healthy and diseased brain samples. Ultimately, the performance is analysed for near-real-time applicability and the advantage of the proposed approach is discussed.
