  • IMAGING APPARATUS, IMAGING METHOD, AND PROGRAM
    Publication number: 20160345837
    Abstract: An image capturing condition of a target portion, such as a tumor, is adjusted while a burden of an examinee is reduced. Deformation of an MRI image obtained in advance is estimated (simulated) such that a shape of a subject in a current holding condition and a shape of the subject in the MRI image coincide with each other. Thereafter, in accordance with an obtained result of the deformation simulation, information on an image capturing condition of the target portion is estimated and displayed for a user. In this way, the user may recognize the image capturing condition in the current holding state. Consequently, risk for holding a breast by excessive holding force and risk for repetitive performance of image capturing due to inefficient holding of the target portion are reduced, and accordingly, a burden of the subject may be reduced.
