INTEGRATED COMPUTED TOMOGRAPHY-POSITRON EMISSION TOMOGRAPHY SYSTEM |
摘要 |
PROBLEM TO BE SOLVED: To provide a medical imaging system using a complex CT-PET system. SOLUTION: A combined emission and transmission imaging apparatus comprises a first and a second photon detector segments disposed face to face on opposite sides of an imaging area (12) for defining the imaging area there between and a radiation source (50) disposed adjacent to and outside of the imaging area (12) and adjacent to at least one detector segment. The radiation source generates a fan beam (80) of radiation emanated from a focal spot (86) and is positioned such that the fan beam is oriented along a trajectory through the imaging area (12) toward the other detector segment. With such a configuration, the segments can collect both emission radiation and transmission radiation. COPYRIGHT: (C)2004,JPO
