    Abstract: Systems, methods, and related computer program products for image-guided radiation treatment (IGRT) are described. For one preferred embodiment, an IGRT apparatus is provided comprising a ring gantry having a central opening and a radiation treatment head coupled to the ring gantry that is rotatable around the central opening in at least a 180 degree arc. For one preferred embodiment, the apparatus further comprises a gantry translation mechanism configured to translate the ring gantry in a direction of a longitudinal axis extending through the central opening. Noncoplanar radiation treatment delivery can thereby be achieved without requiring movement of the patient. For another preferred embodiment, an independently translatable 3D imaging device distinct from the ring gantry is provided for further achieving at least one of pre-treatment imaging and setup imaging of the target tissue volume without requiring movement of the patient.

    Abstract: 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.

    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.

    Abstract: Systems, methods, and related computer program products for image-guided radiation treatment (IGRT) are described. For one preferred embodiment, an IGRT apparatus is provided comprising a ring gantry having a central opening sufficiently large to accommodate a body of a patient positioned along a longitudinal axis and extending therethrough, and a gantry tilting mechanism configured to tilt the ring gantry to a plurality of different tilt angles relative to the longitudinal axis. A radiation treatment head is coupled to the ring gantry and is rotatable around said central opening in at least a 180 degree arc. The radiation treatment head is mechanically coupled to the ring gantry such that a distance by which the radiation treatment head extends inwardly toward the central opening relative to the ring gantry is dynamically controllable.
