A system 10 for imaging includes a gantry 12 movable relative to a subject. A source 14 is configured to emit radiation during an imaging procedure. A detector 18 is configured to receive attenuated radiation from the source 14 during an imaging procedure, at least one of the source 14 and the detector 18 movably secured to the gantry 12 by an adjustable joint 50,54. An imaging controller 28 is operably connected to at least the gantry 12 and to the adjustable joint 50,54, wherein the gantry controller 28 receives a priori patient information and imaging system geometry information, the imaging controller determines an imaging geometry and operates the gantry 12 and the adjustable joint 50,54 to vary a source 14 to image-receptor distance (SID) according to the imaging geometry. |
