Abstract:
Systems and methods directed to adaptive radiotherapy planning are provided. In some aspects, provided system and method include producing synthetic images from magnetic resonance data using relaxometry maps. The method includes applying corrections to the data and generating relaxometry maps therefrom. In other aspects, a method for adapting a radiotherapy plan is provided. The method includes determining an objective function based on dose gradients from an initial dose distribution, and generating an optimized plan based on updated images, using aperture morphing and gradient maintenance algorithms without need for organ-at-risk contouring. In yet other aspects, a method for obtaining 4D MR imaging using a temporal reshuffling of data acquired during normal breathing, a method for deformable image registration using a sequentially applied semi-physical model regularization method for multimodality images, and a method to generate 4D plans using an aperture morphing algorithm based on 4D CT or 4D MR imaging are provided.

Claim (Index 20):
The system of  claim 15 , wherein the computer is further configured to determine the initial radiotherapy plan using an offline optimization process, wherein the offline optimization process uses an accumulated dose from at least one of a plurality of treatment fractions to generate a background representing a plurality of residual errors accumulated from at least one of a plurality of intra-fractional changes.
