Multi-needle Localization for Pelvic Seed Implant Brachytherapy based on Tip-handle Detection and Matching

ArXi:2509.17931v2 Announce Type: replace Accurate multi-needle localization in intraoperative CT images is crucial for optimizing seed placement in pelvic seed implant brachytherapy. However, this task is challenging due to poor image contrast and needle adhesion. This paper presents a novel approach that reframes needle localization as a tip-handle detection and matching problem to overcome these difficulties.
