  • Systems and methods for synthetic photon radiation therapy
    Patent number: 11844963
    Abstract: Example methods and systems for photon energy synthesis and introducing energy modulation into radiation treatment planning process and delivery process are provided. Example methods comprise obtaining, via a linear accelerator, a first photon energy beam dosimetric data, a second photon energy beam dosimetric data, and an intermediate photon energy beam dosimetric data, and fitting the first photon energy beam dosimetric data and the second photon energy beam dosimetric data according to a preset fitting coefficient. A synthesized photon beam is then generated from dosimetric data from the fitted first photon energy beam dosimetric data and the fitted second photon energy beam dosimetric data. Further, continuously variable photon energies can be derived, where two or more existing photon energy beams are combined linearly and applied to both forward and inverse radiation planning modules for a radiation treatment plan.
