Title:
RADIATION DOSE ANALYSIS METHOD, RADIATION DOSE ANALYSIS DEVICE, CONTROL PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/085077
Kind Code:
A1
Abstract:
The present invention accurately evaluates the effects, on organs at risk, of radiation from radiation sources. This radiation dose analysis method comprises a reference axis determination step (S1) for: acquiring a three-dimensional medical image, which is an image obtained by imaging a subject present where an applicator (50) capable of accommodating a radiation source is installed in the vicinity of an object to be irradiated with radiation emitted from the radiation source, said image showing the installed applicator; and determining a reference axis of the applicator (50) shown in the three-dimensional medical image. Said method also comprises a first radiation dose analysis step (S4) for analyzing, on the basis of a distance from the reference axis of each of a plurality of virtual cylindrical surfaces having different radii with the reference axis serving as the central axis, a radiation dose reaching each of the plurality of virtual cylindrical surfaces from the radiation source.
