摘要 |
It is an object to enable an irradiation field to be accurately extracted. An irradiation field extracting method of extracting an irradiation field from a radiation image is constructed by a step of extracting characteristic points in the radiation image by using geometric patterns for detecting an irradiation field edge and a step of detecting an edge portion of the irradiation field on the basis of the characteristic points.
