Embodiment Construction

[0042] figure 1 A part of a proton bench 2 comprising a multilayer parallel plate detector 4 is schematically illustrated. For this part of the proton gantry 2 , a final 90° bending magnet 6 is exemplified, which guides the proton beam 8 parallel to the z-axis towards the patient 10 placed on the patient table 12 . For more details on the design of the proton gantry 2 and the delivery of proton therapy with active scanning of the proton beam 8 and capable of providing an IMPT plan for patient treatment, reference is made to the aforementioned prior art documents incorporated herein by reference.

[0043] Downstream of the patient 10 as seen in the direction of the proton beam 8, a multilayer parallel plate detector 4 is positioned. The detector 4 is designed as a multilayer Faraday cage with a spatial resolution along the z-axis of about 2.5 mm.

[0044] Thus, the present embodiment facilitates the concept of proton "detection range" in order to obtain feedback on the accura...

Abstract

A method for evaluating radiation model data in particle beam radiation applications, in particular in proton beam therapy of a determined target volume of malign tissue within a creature, is disclosed, comprising the steps of: a) gaining diagnostic data for a determined target volume to be irradiated; b) calculating a particle range in the predetermined target volume based on the diagnostic data for the determined target volume; c) designing a radiation model comprising particle beam characteristics based on the calculated particle range and optionally on a calculated dose depth distribution; d) applying a single pencil beam shot to the determined target volume at an elevated beam energy as compared to the particle beam characteristics of the radiation model; e) measuring the beam range of the single pencil beam shot downstream of the determined target volume; and f) comparing the measured beam range to a reference beam range calculated on the basis of the radiation model.

Description

technical field [0001] The invention relates to a method for evaluating radiation model data in particle beam radiation applications. Background technique [0002] Particle therapy, specifically proton therapy, is an advanced method of applying radiation therapy for cancer by using proton beams. It is an advanced but more expensive alternative to conventional treatments usually applied with photon beams. Gantry for proton therapy of this kind has been published and proposed in International Patent Applications WO 2001 / 00276 and WO 2004 / 026401 and in European Patent Application 04 017 266.0 respectively. [0003] When characterizing the difference between photon beam therapy and proton beam therapy, it must be emphasized that the photon beam penetrates the entire body of the patient. The dose distribution is characterized by a maximum dose approximately 1 cm below the skin, followed by a monotonic exponential decrease in dose as a function of depth. Unlike photon beams, pr...
