To investigate the feasibility of three-dimensional fiducial localization using small-angle kV image pairs from adjacent projections as a time-efficient alternative to conventional orthogonal imaging, and to determine the minimum gantry angle separation.

Stereotactic spinal treatments deliver a high radiation dose and utilize smaller target margins, on the order of 1 mm, to minimize dose to the spinal cord. Intrafraction tumor tracking is therefore essential to minimize dose outside of the target. A common ap...
