Abstract:
1. A breast's radiation image taking apparatus, comprising: a radiation source for irradiating a breast of a subject; a breast support plane on which said breast is to be placed; a radiation-receiving plane for acquiring a radiation image of said breast; an imaging position switching means for switching relative positions of said breast support plane and said radiation-receiving plane so that a position of said radiation-receiving plane is switched between a proximal end side, which is near a chest wall of said subject, and a distal end side, which is more spaced from said chest wall than said proximal end side; an imaging mode setting means for setting one of two imaging modes, one imaging mode being a split imaging mode for acquiring an image of a breast of a larger size in which a first radiation image is taken with the radiation-receiving plane positioned on the distal end side and then a second radiation image is taken with the radiation-receiving plane positioned on the proximal end side and other imaging mode being a normal imaging mode for acquiring an image of a breast of a smaller size in which only one radiation image is taken with the radiation-receiving plane positioned on the proximal end side; an imaging condition setting means for setting a first imaging condition on the distal end side when said split imaging mode is set by said imaging mode setting means, and for setting a second imaging condition between the distal end side and the proximal end side when said normal imaging mode is set by said imaging mode setting means; and an imaging control means for controlling said imaging position switching means to switch said position of said radiation-receiving plane from said distal end side to said proximal end side so that the first radiation image and the second radiation image are taken in two positions on the distal and proximal end sides, respectively, under the first imaging condition when said split imaging mode is set by said imaging mode setting means and for controlling said imaging position switching means to position said radiation-receiving plane on the proximal side so that the only one radiation image is taken in a single position on the proximal end side under the second imaging condition when said normal imaging mode is set by said imaging mode setting means.
