Embodiment Construction

[0050] refer to figure 1 , shows an exemplary radiotherapy system 100 that may be used for figure 2 In adaptive radiation therapy as shown in , and which can deliver radiation according to a treatment plan determined using techniques described herein. The radiation therapy system 100 may deliver radiation to a patient 110 on a treatment couch 112 and may allow for various radiation dose verification protocols to be implemented. Radiation therapy may include photon-based radiation therapy, particle therapy, electron beam therapy, or any other type of therapeutic therapy.

[0051] In one embodiment, the radiation therapy system 100 may include a radiation therapy device 101, such as but not limited to a LINAC, operable to generate one or more beams of megavoltage (MV) X-ray radiation for therapy. The LINAC may also be operable to generate one or more beams of kilovolt (kV) X-ray radiation, eg, for patient imaging. The system 100 has a gantry 102 supporting a radiotherapy hea...

Abstract

Systems and methods for automatically generating and optimizing radiation therapy treatment plans, and systems and methods for automatically generating and optimizing adaptive plans in an adaptive radiation therapy workflow. In one embodiment, an automatic treatment planning system includes: a user interface; and a treatment planning module configured to automatically generate S110 one or more treatment planning candidates based on a weighted combination of a first set of targets derived for clinical data of the first data source and a second set of targets derived for clinical data of a different second data source received via the user interface.

Description

technical field [0001] The present invention relates generally to radiation therapy, and more particularly to systems, methods and devices for automatically generating and optimizing radiation therapy treatment plans. Background technique [0002] Radiation therapy involves the use of external radiation beams to treat pathological anatomy by delivering prescribed doses of radiation (X-rays, gamma rays, electrons, protons, and / or ions) while minimizing radiation exposure to surrounding tissues and critical anatomical structures Medical procedures in pathological anatomy (tumors, lesions, vascular malformations, neurological disorders, etc.). [0003] Overall, a complete radiotherapy planning and treatment workflow includes the following phases: a treatment planning phase, a treatment delivery phase, and a monitoring and evaluation phase, where the progress of treatment (eg, dose accumulation) is monitored. [0004] During the treatment planning phase, first use any of comput...
