Benefits of technology

The invention is about a system that scans a beam of charged particles to treat tumors. The technical effect of the patent is to provide a better way to image and treat cancer.

Problems solved by technology

These particles damage the DNA of cells, ultimately causing their death.
Cancerous cells, because of their high rate of division and their reduced ability to repair damaged DNA, are particularly vulnerable to attack on their DNA.

example vii

[0259]In a seventh example, the rolling floor 1320 forms a continuous loop in the cantilevered three hundred sixty degree rotatable gantry system.

example viii

[0260]In an eighth example, an actual position of the cantilevered rotatable gantry system is monitored, determined, and / or confirmed using the fiducial indicators 2040, described, infra, such as a fiducial source and / or a fiducial detector / marker placed on any section of the gantry 490, patient positioning system 1350, and / or patient 230.

Floor Force Directed Gantry System

[0261]Referring now to FIG. 17, a wall mounted gantry system 1700 is illustrated, where a wall mounted gantry 499 is bolted to a first wall 1710, such as a first buttress, with a first set of bolts 1714, optionally using a first mounting element 1712, and mounted to a second wall 1720, such as a second buttress 1720, such a through a second mounting element 1722, with a second set of bolts 1714. The inventor notes that in this design, forces, such as a first force, F1, and a second force, F2, are directed outward into the first wall 1710 and the second wall 1720, respectively, where at least twenty percent of resol...

example iv

[0290]Still referring to FIG. 22, a fourth optional input to the automated radiation treatment plan development system 2200 is structural and / or physical elements present in the treatment room 922. Again, for clarity of presentation and without loss of generality, two cases illustrate treatment room object information as an input to the automated development of the radiation treatment plan 2210.

[0291]Still referring to FIG. 22, in a first case the automated radiation treatment plan development system 2200 is optionally provided with a pre-scan of potentially intervening support structures 2282 input, such as a patient support device, a patient couch, and / or a patient support element, where the pre-scan is an image / density / redirection impact of the support structure on the positively charged particle treatment beam. Preferably, the pre-scan is an actual image or tomogram of the support structure using the actual facility synchrotron, a remotely generated actual image, and / or a calcul...

Abstract

The invention comprises a method and apparatus for scanning charged particles in a cancer therapy system, comprising the steps of: (1) providing a first and second dipole magnet system and a gap, the gap comprising a common gap length, along a path of the charged particles, within both the first and second dipole magnet systems, the gap comprising a progressively increasing x / y-plane cross-section area from an entrance area of the charged particles into the double dipole magnet system to an exit area of the double dipole magnet system, the x / y-plane perpendicular to a z-axis from a center of the entrance area to a center of the exit area; (2) scanning the positively charged particles along a first axis of the x / y-plane using the first dipole magnet system; and (3) scanning the positively charged particles along a second axis of the x / y-plane using the second dipole magnet system.
