    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.
