Variable SID imaging

Abstract:

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