Deep-Learning-Based Multi-Organ Auto-Segmentation on 3D Transrectal Ultrasound for Ultrasound-Guided Prostate Brachytherapy

Purpose/Objective(s)Ultrasound (US) imaging has been widely used in image-guided prostate brachytherapy. Current prostate brachytherapy uses transrectal US (TRUS) images for implant guidance, where contours of prostate and organs-at risk are necessary for treatment planning and dose evaluation. This work aims to develop a deep learning-based method for pelvic multi-organ TRUS segmentation to improve TRUS-guided prostate...
