Two-stage deep learning framework for the restoration of incomplete-ring PET images 事件

Two-stage deep learning framework for the restoration of incomplete-ring PET images arXiv:2504.00816v5 Announce Type: replace Abstract: Positron Emission Tomography (PET) is an important molecular imaging tool widely used in medicine. Traditional PET systems rely on complete detector rings for full angular coverage and reliable data collection. However, incomplete-ring PET scanners have emerged due to hardware failures, cost constraints, or specific clinical needs. Standard reconstruction algor
