摘要： Systems, methods, and related computer program products for image-guided radiation treatment (IGRT) are described. 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. Methods for intra-fraction target tracking in a gantry-style IGRT system based on comparisons between a pre-acquired planning image and intrafraction x-ray tomosynthesis images and/or intrafraction cone beam CT (CBCT) images are also described.

摘要： 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.
