Abstract

Radiation treatment planning includes determining a number of beams to be directed into a target, determining directions (e.g., gantry angles) for the beams, and determining an energy level for each of the beams. The number of beams, the directions of the beams, and the energy levels are determined such that the beams do not overlap outside the target and the prescribed dose will be delivered across the entire target.

Description

[0001] Related U.S. Application [0002] This application is related to U.S. Application No. 15 / 657094, filed July 21, 2017, by R. Vanderstraeten et al., entitled "Dose Aspects of Radiation Therapy Planning and Treatment (Radiation Therapy Planning and Treatment Dose Aspects)," Docket No. VAR- 17-009-US, which is hereby incorporated by reference in its entirety. Background technique [0003] The use of radiation therapy to treat cancer is well known. In general, radiation therapy involves directing beams of high-energy proton, photon, ion, or electron radiation ("therapeutic radiation") into a target or target volume (eg, a tumor or lesion). [0004] Before treating a patient with radiation, develop a treatment plan for that patient. Planning is based on past experience, using simulation and optimization to define aspects of the therapy. Typically, the goal of treatment planning is to deliver sufficient radiation to the target while minimizing radiation exposure to surroun...
