Abstract: Systems and methods are provided for radiation delivery. An exemplary method includes receiving an image depicting anatomical data of a target region of patient tissue and determining an initial prescribed dose of radiotherapeutic radiation to be delivered to the target region. The method also includes discretizing the arc for VMAT into a plurality of arc segments and performing an iteration process for determining an arc dose according to radiation delivered in the arc segments. The method further includes determining whether a condition for terminating the iteration process is met and terminating the iteration process based on a result of the determination that the condition for terminating the iteration process is met.

Abstract: The disclosed systems and methods for Image-Guided Radiation Therapy (IGRT), utilises an iterative approach which adjusts a treatment plan based on inter- or intra-fraction images to improve the accuracy of the radiation delivered during the overall treatment. The prescribed dose of radiotherapeutic radiation is mapped onto the patient's anatomy using an image acquired of the region, which is to be the target for radiotherapeutic radiation. Following beam-angle-optimisation, fluence optimisation and segmentation, the efficiency of delivery of each segment is determined using an objective function, and the segments ranked according to their efficiency. The plan proceeds with the choice of the most efficient segment (or segments) to be delivered first.
