Abstract: A modular PET gantry is provided herein. A detector module is described, and the detector module includes a plurality of PET detector units. Each detector unit may be bonded to a mounting sleeve. The detector module also includes a mounting frame, wherein each detector unit and mounting sleeve is attached to the mounting frame.

Abstract: 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.

Abstract: A detector unit for a detector array includes a photo sensor array, a light guide, and a plurality of scintillator elements formed unitarily with the light guide, the scintillator elements configured to emit absorbed energy in the form of light, the light guide being configured to transmit the light received from at least one of the scintillator elements to a photo sensor, the light guide and the plurality of scintillators being formed from the same material, an area covered by the photo sensors being smaller than an area covered by the scintillator elements and a number of photo sensors being less than a number of scintillator elements. A detector array and a method of manufacturing a detector array are also described herein.

Abstract: A cable fastener is disclosed. The cable fastener includes a first portion and a second portion. A set of threads is disposed at a first end of the first portion, and a knurl is disposed at a second end of the first portion. The second portion includes an interface region disposed within a first end and a tool interface disposed upon a second end. The interface region is disposed in intimate connection upon the knurl, and the first and second portion are configured to transmit at least 12 in-lbs across the interface region and knurl without relative motion.
