Abstract: Systems and methods for radiation treatment planning that integrate the MV therapeutic radiation dose imparted to a subject together with the kV imaging radiation dose imparted to a subject during radiation therapy are provided. For instance, dose optimization is based on the combined effect of both a kV imaging dose that is imparted to the subject during the image guided radiation treatment procedure and the therapeutic dose delivered to the subject by a treatment radiation source, such as an MV source. Using this optimization, the kV beam and MV beam are equally treated as radiation producing sources and are thus optimized together at the treatment planning stage to produce a patient treatment plan that optimally uses the kV imaging dose. Thus, the kV beam is treated both as an additional source of therapeutic radiation and as a tool for imaging the subject.

The OAR distance to target map includes distances to a target organ for respective portions of an OAR, and the OAR distances are determined from a segmented patient organ image.

A second 3D dose distribution map is determined based on a field arrangement determined by the treatment type, and the first 3D dose distribution map. A dose distance to target histogram is calculated using the second 3D dose distribution map and the distance to target map.

Abstract: Photon-based radiosurgery is widely used for treating local and regional tumors. The key to improving the quality of radiosurgery is to increase the dose falloff rate from high dose regions inside the tumor to low dose regions of nearby healthy tissues and structures. Dynamic photon painting (DPP) further increases dose falloff rate by treating a target by moving a beam source along a dynamic trajectory, where the speed, direction and even dose rate of the beam source change constantly during irradiation. DPP creates dose gradient that rivals proton Bragg Peak and outperforms Gamma Knife® radiosurgery.

Hence, the disturbance to the X-ray beam is negligible.
