Understanding From Human Perspective: A Multi-agent System for Interactive Egocentric Medical Image Segmentation

Rongjun Ge, Dongyang Wang, Heng Zhu, Zhirui Li, Yang Chen, Yuting He

Interactive egocentric medical image segmentation (IEMIS) plays an important role in smart-glasses-assisted medical image review, segmenting the medical targets a clinician refers to from their egocentric view. Once it succeeds, the object-level visual evidence it provides streng…

From Data Completeness to Data Sufficiency: A Task-Driven Imaging Framework for Intraoperative CBCT under Quality-Time-Dose Trade-offs

Yi Jia, Rongjun Ge, Yang Chen, Yan Xi, Wenjun Xia

Mobile C-arm cone-beam computed tomography (CBCT) has been widely used for real-time intraoperative 3D imaging. However, current practice often mechanically applies the fan-beam CT criterion of "180° plus fan angle" in pursuit of "data completeness" in reconstruction. This review…
