Abstract
Organ-specific PET scanners continues to draw interest for their high-resolution imaging capability that is unmatched by whole-body PET/computed tomography (CT) scanners. The virtual-pinhole PET concept offers new opportunities in PET system design, allowing one to mix and match detectors of different characteristics to achieve the highest performance such as high image resolution, high system sensitivity, and large imaging field-of-view. This novel approach delivers high-resolution PET images previously available only through organ-specific PET scanner while maintaining the imaging field-of-view of a clinical PET/CT scanner to see the entire body.
摘要
器官特异性 PET 扫描仪因其高分辨率成像能力而备受关注，这种能力是全身 PET/计算机断层扫描（CT）扫描仪无法比拟的。虚拟小孔 PET 概念为 PET 系统设计提供了新的机会，允许混合和匹配具有不同特性的探测器，以实现最高性能，如高图像分辨率、高系统灵敏度和大成像视野。这种新方法提供了以前只能通过器官特异性 PET 扫描仪获得的高分辨率 PET 图像，同时保持了临床 PET/CT 扫描仪的成像视野，以观察整个身体。
