摘要：
A system and method are provided for obtaining data that may be used to generate images of a brain or other bodily organ. The system can include a pair of detecting arrangements and a collimating arrangement associated with each detecting arrangement. A first collimating arrangement can include a cone-beam collimating arrangement having a focal point located within the brain or other organ being imaged. A second collimating arrangement can include a fan-beam collimating arrangement having a focal length selected such that the organ being imaged lies within its field of view to ensure data sufficiency. Cone-beam collimating arrangements having improved hole geometries can also be utilized to provide further increases in imaging sensitivity.
摘要（中）：
提供了一种用于获得可用于生成脑或其他身体器官的图像的数据的系统和方法。 该系统可以包括一对检测装置和与每个检测装置相关的准直装置。 第一准直装置可以包括具有位于成像的脑或其他器官内的焦点的锥形束准直装置。 第二准直装置可以包括具有选择的焦距的扇形束准直装置，使得成像的器官位于其视野内以确保数据充足。 具有改进的孔几何形状的锥束准直装置也可用于提供成像灵敏度的进一步增加。
