Abstract
An apparatus to perform a CT scan of an object of interest with a reduced radiation dose including: an X-ray source configured to circularly rotate about the object of interest, the X-ray source configured to generate an X-ray beam; a detector assembly configured to move in tandem with the X-ray source on the opposite side of the X-ray source with respect to the object of interest, wherein the detector assembly is fixed with respect to the X-ray source and configured to detect the X-ray beam on a side of the object of interest opposite to the X-ray source after the X-ray beam passes through the object of interest; a 6-DOF collimator coupled to the X-ray source and comprising a plate with a hole disposed within the plate, wherein an aperture of the X-ray beam is dynamically adjusted by controlling a 3-D pose of the plate.
