Title:
NEUTRON DOSE MEASUREMENT METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/116615
Kind Code:
A2
Abstract:
Provided in one aspect of the present invention is a neutron dose measurement method. The method comprises: determining a unit to be corrected that corresponds to a dose monitoring system; determining a first correction factor on the basis of the number of rays emitted, after neutron activation, by a nonmetal unit to be activated, and the unit to be corrected that corresponds to the dose monitoring system; and correcting the dose monitoring system on the basis of the first correction factor, so as to determine a real-time neutron dose of a patient. By means of the present application, a first correction factor is determined to correct the sensitivity of a dose monitoring system, so as to determine a real-time neutron dose of a patient, such that a measurement error caused by a sensitivity reduction or a position change in the dose monitoring system is avoided, thereby improving the accuracy and reliability of a measurement result. Provided in another aspect of the present invention is a neutron dose measurement apparatus corresponding to the method.
