An examination executor of an ultrasound examination is easily able to identify a position corresponding to an attention area on a medical image acquired in an X-ray examination on an imaging-object region, when the X-ray examination and the ultrasound examination are performed as separate examinations.In the medical imaging system (100), the control part (31) of the server device (3), estimates a position of an attention area specified on a breast image in the image display device (4) in a breast as viewed from the front, on the basis of the position of the attention area in the breast image and an angle at which an X-ray photographing device is inclined during breast imaging. Then the control part (31) produces estimated clinical position information and causes the display part 43 of the image display device (4) to display the produced estimated clinical position information.
