There is provided an imaging slice setting technique capable of reducing the burden on the operator and having high accuracy and a high degree of freedom. In order to do so, a standard imaging slice is registered in the system in advance, and a GUI allowing the operator to appropriately adjust the standard imaging slice is provided. The standard imaging slice is displayed on a standard image configured to include two-dimensional images in three directions similar to a positioning image, and can be adjusted on the image. At the time of main imaging, the standard image is fitted to the positioning image to specify an imaging slice on the positioning image.
