Summary:A computer-assisted medical system comprising a fluoroscopic imager having a full scan range in a surgical coordinate space and one or more processors. The processors are configured to perform a method including: receiving a first fluoroscopic image data set of a patient anatomy, the first fluoroscopic image data set obtained from the full scan range of the fluoroscopic imager; receiving at least one additional fluoroscopic image data set of the patient anatomy from the fluoroscopic imager operating in a constrained range substantially smaller than the full scan range; and constructing a first planar tomographic image from the first and at least one additional fluoroscopic image data sets.
