1. An imaging system comprising:
a digital radiation detector;
a detector transport to move the digital radiation detector along at least a portion of a first curved path, the at least a portion of the first curved path extending at least partially around the head of a patient at a distance D1 from a central axis of the first curved path;
a radiation source;
a radiation transport to move the radiation source along at least a portion of a second curved source path outside the first curved path, the second curved source path extending at least partially around the head of the patient and having a distance D2 from the central axis greater than the distance D1;
wherein the digital radiation detector is configured to travel at least a portion of the first curved path, the radiation source is configured to travel at least a portion of the second curved source path, the distance D2 is sufficiently long to allow sufficient radiation exposure of the head for a CBCT image capture by the digital radiation detector, and wherein the digital radiation detector is configured to obtain a plurality of 2D projection images over a range of image capture scan angles;
a processor to reconstruct a 3D volume using more than one of the plurality of 2D projection images; and
a substantially circular housing configured to contain the radiation source, the digital radiation detector, the radiation transport, and the detector transport, the substantially circular housing including an examination opening for placement of the head of the patient.
