Increased cone beam computed tomography volume length without requiring stitching or longitudinal c-arm movement

A medical imaging system comprising:

• a movable station including a C-arm having a first end and a second end that are movable along an arc relative to the movable station;
• a collector attached to the first end of the C-arm;
• a first X-ray beam emitter and a second X-ray beam emitter both facing the collector to emit X-ray beams in a direction of the collector and both attached to the second end of the C-arm;
• the collector and the first and second X-ray beam emitters are spaced apart relative to each other along a lateral axis orthogonal to the arc;
• and
• a controller configured to obtain at least one set of images by rotating the collector and the first and second X-ray beam emitters along the arc about a scanned volume, and to combine the at least one set of images to generate a three-dimensional image of the scanned volume.

A computer program product comprising a non-transitory computer readable medium storing program code executable by at least one processor of a controller of a medical imaging system for X-ray imaging to:

• move one of an X-ray beam emitter and a collector to a first offset position relative to each other along a lateral axis orthogonal to an arc,
• obtain a first set of images by rotating the collector and a X-ray beam emitter along the arc about a scanned volume while the X-ray beam emitter and the collector are positioned with the first offset position,
• move the one of the X-ray beam emitter and the collector to a second offset position relative to each other along the lateral axis orthogonal to the arc,
• obtain a second set of images by rotating the collector and the X-ray beam emitter along the arc about the scanned volume while the X-ray beam emitter and the collector are positioned with the second offset position, and
• combine the first and second set of images to generate a three-dimensional image of the scanned volume.
