PROBLEM TO BE SOLVED: To achieve excellent targeting while suppressing radioactive exposure dose in a stereotactic biopsy device.SOLUTION: A radiographic image of a breast M is stereoscopically displayed to accept designation of a puncture position TP, on the basis of first image data D1 and second image data D2, of image data D1, D2, D3 obtained by radiographing the breast M in different three directions C1, C2, C3. The position of three-dimensional coordinates of the puncture position TP is acquired on the basis of the first image data D1 and the third image data D3. In this case, a first congestion angle &Dgr;&thetas;1 based on the first imaging direction C1 and the second imaging direction C2 is made smaller than a second congestion angle &Dgr;&thetas;2 based on the first imaging direction C1 and the third imaging direction C3. |
