New techniques for radiotherapy and radiosurgery are provided. In one aspect of the invention, multiple sources of radiation are provided in a planned frequency and in the same superposable period and polarization, from the same side of a treatment target, focused on a leading structure in the target. In another aspect, refractive models, updated by live feedback, are used to improve dosage distribution by, among other things, optimizing the number, angle and nature of radiation beams. Interstitial beacons and radiation path diversion structures are inserted to improve dosage distribution to a target and avoid critical neighboring structures. In particle therapy, regionally actuable external magnetic fields are used as well, to improve dosage accuracy and avoid collateral damage.
