Abstract: Imaging guided radiation treatment apparatus and methods are described. A method includes processing a first population of x-ray cone beam projection images to compute therefrom a time sequence of sliding-window tomographic image volumes characterized in that each subsequent member of the time sequence is computed using at least one same x-ray cone beam projection image as used in computing at least one previous member of the time sequence. The method also includes operating an IGRT apparatus to deliver treatment radiation to the target based at least in part on a comparison between at least one of the time sequence of sliding-window tomographic image volumes and a pre-acquired image data set.

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.

Abstract: Treatment targets such as tumors or lesions, located within an anatomical region that undergoes motion (which may be periodic with cycle P) are tracked. A 4D mathematical model may be established for the non-rigid motion and deformation of the anatomical region, from a set of CT or other 3D images. The 4D mathematical model relates the 3D locations of part(s) of the anatomical region with the targets being tracked, as a function of the position in time within P. Using non-rigid image registration between pre-operative and intra-operative images, the position of the target and/or other part(s) of the anatomical region may be determined.

Provided according to one preferred embodiment is an IGRT apparatus including a barrel-style rotatable gantry structure that provides high mechanical stability, versatility in radiation delivery, and versatility in target tracking. Methods for treatment radiation delivery using the IGRT apparatus include conical non-coplanar rotational arc therapy and cono-helical non-coplanar rotational arc therapy. A radiation treatment head (MV source) and a treatment guidance imaging system including a kV imaging source are mounted to and rotatable with a common barrel-style rotatable gantry structure, or alternatively the MV and kV sources are mounted to separate barrel-style rotatable gantry structures independently rotatable around a common axis of rotation.

Abstract: Systems, methods, and related computer program products for medical imaging and image-guided radiation treatment (IGRT) are described. In one preferred embodiment, an IGRT system provides intrafraction target tracking based on a comparison of intrafraction x-ray tomosynthesis image data with initial x-ray tomosynthesis image data acquired with the patient in an initial treatment position, the initial x-ray tomosynthesis image data having an inherent registration with co-acquired image data from a setup imaging system integral with, or having known geometry relative to, the tomosynthesis imaging system. Repeated registration of intrafraction x-ray tomosynthesis image data with pre-acquired reference image data from a different frame of reference is not required during intrafraction radiation delivery. Advantages include streamlined intrafraction computation and/or reduced treatment delivery margins.
