Abstract
The invention discloses a rack wheel regulation system and a method for regulating the rack wheel of a proton treatment system. The rack wheel regulation system comprises an estimation unit which estimates the support member regulation value of each regulation support member on the basis of the rigid parameters; the rigid parameters are the deviation function of the force applied on each regulation support member and the force applied on the regulation support member; the support member regulation value is corresponded to the nominal position value for compensating the rack wheel flexure when the rack wheel is rotated from a first angle position to a second angle position; and the adjustable support member is configured to support the rack wheel on the support surface and retains the proton in the center of the rack wheel when the rack wheel is rotating.
Description
[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of U.S. Application No. 14 / 064,732, filed October 28, 2013, which claims U.S. Provisional Patent Application No. 61 / 719,129, filed October 26, 2012 and September 20, 2013 Priority to U.S. Provisional Patent Application No. 61 / 880,605 filed on , the disclosures of both U.S. Provisional Patent Applications are incorporated herein by reference. technical field [0003] The present general inventive concept relates to a rotating gantry system, and more particularly, to systems and methods for adjusting a rotating gantry system for proton therapy to maintain alignment of an ae proton delivery mechanism with the axis of rotation of the gantry. Background technique [0004] Proton therapy (PT) is a cancer treatment technique that uses high-energy protons to penetrate a patient's body and deposit energy into a treatment area, such as a cancerous tumor. PT systems often employ rotatin...
