New techniques for radiotherapy and radiosurgery are provided. In some aspects of the invention, multiple sources of radiation with characteristics that are projected to constructively interfere at a treatment target are provided. In other aspects, hardware directs multiple radiation sources from the same side of a treatment target, and focuses the initiation of substantial interference on a leading structure in the target. In other aspects, refractive models updated by live feedback are used to improve dosage distribution by, among other things, optimizing the number, length, superposition, overlap, angle and nature of radiation beams. In additional aspects, 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 also provided, to improve dosage accuracy and avoid collateral damage.

1. An electromagnetic radiation-based treatment system comprising hardware configured to: cause multiple beams comprising radiation waves in each beam of substantially the same frequency, and/or of a harmonic or otherwise related frequency, when said waves converge to converge on, superpose and perform treatment with a superposed waveform on a treatment target; andprotect material in between a source of said radiation waves and said treatment target by causing multiple beams comprising radiation waves in each beam of substantially the same frequency to superpose and destructively interfere, and/or to constructively superpose to a lower degree within said material than at the treatment target. 2. The electromagnetic radiation-based treatment system of claim 1, in which at least some of said comprised radiation waves in each beam share the same or a constructively matched polarity. 3. The electromagnetic radiation-based treatment system of claim 2, in which at least some of said comprised radiation waves in each beam constructively interfere with other waves. 4. The electromagnetic radiation-based treatment system of claim 3, in which said constructive interference results from at least some of said comprised waves in each beam being in the same phase as they converge upon a treatment target volume. 5. The electromagnetic radiation-based treatment system of claim 1, in which at least some of said comprised waves in each beam interfere to produce a superposition of higher frequency than said comprised waves in each beam, as they converge upon a target volume. 6. The electromagnetic radiation-based treatment system of claim 1, in which at least some of said comprised waves in each beam converge on leading portions or the leading volume of the treatment target. 7. The electromagnetic radiation-based treatment system of claim 1, in which at least some of said comprised waves in each beam originate from the same side of said treatment target. 8. A method for treating an electromagnetic radiation-based or other wave phenomenon-based treatment target, comprising the following steps: employing location information concerning a group of material to define the location of a treatment target;aiming multiple beams of radiation or paths or instances of wave phenomenon, or aiming a diffuse beam of radiation or wave phenomenon, at said treatment target from the same side of said treatment target, which beam(s) of radiation or paths or instances wave phenomenon are in the same polarization, phase, and/or frequency; andinserting a lens or other radiation path diversion device, which device focuses diffuse radiation within material collateral to said treatment target onto said treatment target and/or around at least one structure collateral to said treatment target. 9. The method for treating an electromagnetic radiation-based or other wave phenomenon-based treatment target of claim 8, comprising the following additional step: inserting a beacon within material collateral to said treatment target against, near, within or otherwise substantially locatable in relation with said treatment target, to aid in location of said treatment target during treatment. 10. The method for treating an electromagnetic radiation-based or other wave phenomenon-based treatment target of claim 8, comprising the following additional step: determining the location and/or orientation of said lens or other radiation path diversion device; andadjusting the location and/or orientation of said lens or other radiation path diversion device. 11. The electromagnetic radiation-based or other wave phenomenon-based treatment system of claim 1, in which refraction models are used by the system and/or user to achieve optimized protection of collateral material or media and/or treatment of a target volume. 12. The electromagnetic radiation-based or other wave phenomenon-based treatment system of claim 11, in which said refraction models are corrected by live data, and additional or changed beam(s) comprising radiation or other waves in each beam, or path(s), angle(s) or instance(s), strength(s) or at least one other aspect(s) or characteristic(s) thereof, may be introduced based on the live data to optimize a radiation dosage and/or distribution. 13. The electromagnetic radiation-based or other wave phenomenon-based treatment system of claim 12, in which treatment target size-related pulse lengths of radiation or other waves are caused to overlap in a reduced and/or dispersed manner across regions collateral to the treatment target. 14. A method for treating a radiation-based treatment target, comprising the following steps: employing location information concerning a group of material to define the location of a treatment target;aiming at least one beam of particle-based radiation at said treatment target;using a locally-actuated, regionally changing magnetic field to alter the path of a particle-based radiation beam, such that it circumvents at least one structure and enters the treatment target. 15. The electromagnetic radiation-based or other wave phenomenon-based treatment system of claim 1, in which a gantry spins multiple sources of radiation around one another to achieve varying, spiral-shaped dosage patterns that intersect at a target volume. 16. The method for treating an electromagnetic radiation-based or other wave phenomenon-based treatment target of claim 8, comprising the following additional step: inserting a radiation-focusing mirror or lens into material collateral to a treatment target with the aid of an instrument comprising said mirror or lens inserted into a subject of the treatment.
