Abstract:
1. A method of controlling a radiation image capturing apparatus for capturing a radiation image of a subject, comprising the steps of: applying a radiation from a radiation source to a region to be imaged of the subject; detecting a dose of the radiation which has passed through said region to be imaged at a plurality of radiation dose measuring positions; multiplying respective pieces of radiation dose information measured at said radiation dose measuring positions by respective weighting coefficients depending on said radiation dose measuring positions for selecting one or more of said radiation dose measuring positions based on the radiation dose information multiplied by said weighting coefficients; determining an exposure control condition for the radiation from said radiation source based on said radiation dose information measured at the selected one or more radiation dose measuring positions; and wherein said region to be imaged comprises a breast of the subject, and said step of multiplying respective pieces of the radiation dose information comprises the step of multiplying the pieces of the radiation dose information by weighting coefficients established to preferentially select said one or more of said radiation dose measuring positions which are closer to the center of the breast than to the peripheral region thereof along the chest wall of the subject.
