Abstract
A method of image guided radiation treatment (IGRT) is described. The method may include receiving a pre-acquired image data set of the body part acquired in a reference frame generally independent of a reference frame of an IGRT apparatus, processing a first population of x-ray cone beam projection images to compute therefrom a first tomosynthesis image volume; and operating a radiation treatment head of the IGRT apparatus to deliver treatment radiation to the body part based at least in part on a comparison between the first tomosynthesis image volume a pre-acquired image data set of the body part.
