Abstract

The invention provides a system and method for three-dimensional dose verification in radiosurgery. First a patient's image data and radiotherapy planning data are led in through a data management module, a patient's actual illuminated three-dimensional dose field distribution during the treatment is quickly reconstructed by utilization of a two-dimensional field size dosage collecting module and a three-dimensional dose inversion module; three-dimensional evaluation analysis is performed on a irradiation dose and a planning dose through a dose evaluation module; whether an error is in a permissible range is judged; if the error is in the permissible range, the patient is treated according to a radiotherapy plan, or else the radiotherapy plan is adjusted or a radiosurgery accelerator is subjected to quality control detection, irradiation is not performed on the patient until the dose verification passes, and the consistency between the irradiation dose and the planning dose is guaranteed finally. According to the system and method for three-dimensional dose verification in radiosurgery, the shortcoming of two-dimensional plane dose verification of using water instead of a person prior to existing treatment is overcome, and precise dose verification of three-dimensional space dose field distribution in the patient prior to fractionated treatment and during the fractionated treatment can be implemented.

Description

technical field [0001] The invention relates to a three-dimensional dose verification system and verification method in radiotherapy, which belongs to the direction of precise radiotherapy dose verification and instrument device improvement in multidisciplinary interdisciplinary fields such as nuclear physics, nuclear technology and application, and radiology. Background technique [0002] The key to ensuring the therapeutic effect of radiotherapy is to ensure that the tumor target area receives a sufficient lethal dose, and at the same time, make the dose received by normal tissues and organs at risk within the tolerance range. In order to improve the curative effect of radiotherapy, radiotherapy technology has been continuously developed, from the initial ordinary radiotherapy to three-dimensional conformal radiotherapy (CRT), intensity-modulated radiotherapy (IMRT) and image-guided radiotherapy (IGRT). No matter what kind of radiotherapy technology is used, in order to en...
