Problems solved by technology

What is satisfied may be questions such as: (1) whether enough doses are sufficient to reach tumors; (2) whether too many doses reach certain parts of tumors; and / or (3) how much doses reach healthy individuals not identified as tumors structure
These constraints limit the treatment plans that users can design

Embodiment Construction

[0065] The present invention will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the illustrated embodiments set forth. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like components throughout the drawings, and primed symbols, if used, indicate like components in other embodiments.

[0066] Modern radiation therapy devices, such as linear accelerators ("LINACs"), irradiate tumor sites by generating multiple channels along varying arcs that approach the target volume along different entry paths, each pointing toward a The point at the center of the target volume, often called the isocenter of the treatment volume. Each pass of the treatment bea...

Abstract

A system and associated methods to determine an optimal radiation beam arrangement are provided. The system includes a computer planning apparatus which includes a treatment plan optimization computer having a memory and an input device in communication with the treatment plan optimization computer to provide user access to control functions of plan optimization software. An image gathering device is in communication with the treatment plan optimization computer through a communications network to provide an image slice of the tumor target volume and the non-target structure volume. The plan optimization software computationally obtains and then optimizes a proposed radiation beam arrangement iteratively based on constraints to form an optimized radiation beam arrangement. A conformal radiation therapy delivery device in communication with the treatment plan optimization computer through the communications network then applies the optimized radiation beam arrangement to the patient.

Description

[0001] related application [0002] This application claims under 35 U.S.C. § 119(e) of U.S. Provisional Application No. 60 / 518,020, filed October 7, 2003, entitled "Planning System, Method, and Apparatus for Conformal Radiation Therapy" benefit, this application is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates generally to radiation therapy, more particularly to conformal radiation therapy of tumors, and more particularly to radiation therapy treatment planning systems, methods and apparatus for conformal radiation therapy. Background technique [0004] Currently, radiation therapy for tumors has two goals: to eradicate the tumor and to avoid damaging healthy tissues and organs that exist near the tumor. It is known that the vast majority of tumors can be completely eradicated if sufficient radiation doses are delivered to the tumor volume; Complications due to effective radiation dose. The goal of conformal radi...
