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.

Variable SID imaging

Various methods and systems are provided for collision avoidance in cone-beam computed tomography (CT) systems. In one embodiment, a method for an imaging apparatus comprises calculating a likelihood of a collision between the imaging apparatus and a subject and/or its support based on a model of the subject, performing a scan of the subject responsive to the likelihood below a threshold, and not performing the scan otherwise. In this way, collisions between the patient and the imaging apparatus can be avoided.
