Claim Text:
1. A method, of applying x-ray radiation to target tissue, comprising: obtaining imaging data indicative of a target tissue; identifying, based on the imaging data, a location of the target tissue; repeatedly mapping the location of the target tissue in a coordinate system, thereby producing mapped locations of the target tissue in the coordinate system; positioning, based on the mapped locations of the target tissue in the coordinate system, an x-ray collimator that directs an x-ray beam to the target tissue; and emitting the x-ray beam from the collimator to the target tissue, wherein the x-ray beam has a dose distribution at a beam spot in a plane at the target tissue, such that a dose of the x-ray beam at a region within the plane and outside the beam spot is less than 20% of a dose at a centroid of the beam spot.
