报告摘要：

We investigated the feasibility of a novel positron emission tomography (PET) system that provides near real-time feedback to an operator who can interactively scan a patient to optimize image quality. The system is compact and mobile to support point-of-care (POC) molecular imaging applications. The core of this novel PET technology includes trackable PET detectors and a fully 3D, fast image reconstruction engine implemented on multiple graphics processing units (GPUs) to support dynamically changing geometry by calculating the system matrix on-the-fly using a tube-of-response approach. With near real-time image reconstruction capability, a POC-PET system may comprise a maneuverable front PET detector and a second detector panel which can be stationary or moved synchronously with the front detector such that both panels face the region-of-interest (ROI) with the detector trajectory contoured around a patient’s body. This technology is not meant to compete with clinical PET scanners that are optimized for WB-PET imaging applications. Instead, it is designed to image a user-selected ROI in a patient. Different from other organ-specific PET scanners that are optimized for a specific body part, the proposed technology is designed to provide maximal flexibility and versatility.
