Abstract: A radiation detector head assembly includes a detector column including a detector having a first surface and a second surface opposite the first surface. The detector column includes a first collimator disposed over the first surface of the detector and a second collimator disposed over the second surface of the detector. The detector column includes a first radiation shield disposed over the first collimator, wherein the first radiation shield includes a first recess for receiving the first collimator and a first opening over a third surface of the first collimator, the third surface being opposite the first surface of the detector. The detector column includes a second radiation shield disposed over the second collimator, wherein the second radiation shield includes a second recess for receiving the second collimator and a second opening over a fourth surface of the second collimator, the fourth surface being opposite the second surface.

Abstract: Various methods and systems are provided for multi-modal medical imaging systems. In one embodiment, a medical imaging system comprises a first gantry including a first bore and a second gantry including a second bore each adapted to receive a subject to be imaged by the medical imaging system, with the first bore having a first isocenter line and the second bore having a second isocenter line, where the first isocenter line and second isocenter line are offset from each other.

Abstract: An imaging system comprises an adaptor plate configured to be removably coupled to a gantry structure of the imaging system, a plurality of detectors configured to be removably coupled to the adaptor plate, and one or more conduits for a fluid to flow through, wherein the fluid is used to cool the imaging system.
