A CT system is disclosed that includes detector modules positioned on a rotatable gantry configured to receive x-rays attenuated by an object. Each detector module includes a module frame, a plurality of tileable sub-modules on the module frame aligned along a Z-axis thereof to receive the x-rays attenuated by the object and convert the x-rays to digital signals, and an electronics board connected to the plurality of sub-modules to receive the digital signals. Each sub-module further includes an array of detector elements to receive x-rays attenuated through the object and convert the x-rays into analog electrical signals, an ASIC electronics package coupled to the array of detector elements to receive the analog electrical signals and convert the analog electrical signals to digital signals, and a flex circuit connected to the ASIC electronics package to receive the digital signals and transfer the digital signals to the electronics board.

Multi-slice CT detector with tileable packaging structure

A method of fabricating a detector includes providing a photodiode part, providing a scintillator part, at least one of the photodiode part and the scintillator part including a non-active portion and an active portion, placing a first adhesive such that the first adhesive contacts the active portion when the detector is assembled, placing a second adhesive such that the second adhesive contacts the non-active portion when the detector is assembled, the second adhesive having a faster cure time than the first adhesive, and biasing the photodiode part and the scintillator part toward each other until the second adhesive has cured.

X-ray detector fabrication methods and apparatus therefrom

Methods and systems for assembling an X-ray imaging system are provided. The method for assembling an X-ray imaging system includes fabricating a rail that includes an arcuate member. The arcuate member includes a plurality of substantially planar facets that are circumferentially spaced about an outer periphery of the rail. The method further includes coupling a sensor array to at least one of the plurality of facets such that at least a portion of a substantially planar face of the sensor array mates in thermally conductive engagement with the facet.
