Systems and methods for integration of a positron emission tomography (PET) detector with a computed-tomography (CT) gantry

摘要

Systems and methods for integration of a PET detector with a CT gantry are provided. One system includes an x-ray computed tomography (CT) gantry having a rotating portion and a stationary portion within a housing, and including a bore volume therethrough. The system also includes an x-ray source and an x-ray detector coupled to the rotating portion. The system further includes a positron emission tomography (PET) detector, wherein the PET detector is coupled to the stationary portion of the CT gantry, such that the PET detector extends at least partially into the CT gantry with at least a portion of the PET detector within the housing of the CT gantry.

1. An imaging system comprising:
an x-ray computed tomography (CT) gantry having a rotating portion, a stationary portion, and a housing, the rotating portion and the stationary portion disposed within the housing, and the CT gantry including a bore volume through the rotating portion, the rotating portion of the CT gantry disposed radially inward of the stationary portion, and the rotating portion and stationary portion at least partially overlapping along an examination axis passing through the bore along a length of the bore; an x-ray source and an x-ray detector, wherein the x-ray source and the x-ray detector are coupled to the rotating portion and are configured to rotate with the rotating portion; a positron emission tomography (PET) support structure adjacent to the stationary portion of the CT gantry in an axial direction extending along the examination axis; and a PET detector, the PET detector coupled to the stationary portion of the CT gantry via the PET support structure, the PET detector extending at least partially into the CT gantry, such that at least a portion of the PET detector is within the housing of the CT gantry, the PET detector spaced axially along the examination axis along the length of the bore from the x-ray detector, the PET detector at least partially overlapping the stationary portion of the CT gantry along the examination axis.
