Abstract

The invention provides a method for migrating radiotherapy plans on a Pinnacle therapy planning system. The method includes steps of 1), setting irradiation isocenter points on reduction CT (computed tomography) image spaces according to first-time radiotherapy plants; 2), executing script programs and exporting irradiation field parameters in the first-time radiotherapy plans; 3), executing script programs and importing the irradiation field parameters of the first-time radiotherapy plans into the reduction CT image spaces; 4), executing script programs, setting weights of various irradiation fields of the radiotherapy plans imported into the reduction CT image spaces and migrating the radiotherapy plans in the different CT image spaces. The method has the advantages that distribution conditions of projection dose in the bodies of patients according to the first-time radiotherapy plans can be represented in the reduction CT image spaces by the aid of the method, accordingly, the human organ radiated dose evaluation flexibility and precision of the Pinnacle therapy planning system can be improved, radiotherapy doctors and radiation physicists can conveniently and quickly develop adaptive radiotherapy on the patients by the aid of the Pinnacle therapy planning system, and individual therapeutic schemes can be formulated for the patients by the radiotherapy therapists and the radiation physicists by the aid of the Pinnacle therapy planning system.

Description

technical field

[0001] The invention relates to the technical field of computer application in tumor radiotherapy planning, in particular to a method for implementing radiotherapy plan transplantation on a Pinnacle treatment planning system. Background technique

[0002] Basic process of tumor radiotherapy

[0003] For each confirmed patient receiving radiotherapy, the basic process of treatment, such as figure 1 As shown, including "①CT positioning (obtain "first-pass CT") → ② plan design (get "first-pass plan") → ③ implement treatment under accelerator → after a period of treatment → ④ CT reset (get "reset CT") → ⑤ Redesign the radiotherapy plan (get "reset plan") → ⑥ implement treatment under the accelerator according to the reset plan". Among them, ④⑤⑥ may appear more than once. A detailed explanation of each step is as follows:

[0004] ①CT positioning: also called CT simulation positioning, that is, the patient is fixed on the CT scanning bed through auxiliary equ...
