Conventionally, the procedure for obtaining morphological information and functional information regarding the same region of the same subject as described above is performed as follows.

That is, generally, a magnetic resonance imaging device and a 5PECT device installed in separate rooms are used.

For example, a patient enters an examination room equipped with a magnetic resonance imaging device, where the patient sits on the bed of the magnetic resonance imaging device, and a doctor or the like obtains a tomographic image of an axial plane at a specific location in the center of the brain. Through a positioning procedure, an MR tomographic image is obtained and displayed on a display device. This MR tomographic image is imprinted on a film or magnetically recorded for comparison with a nuclear medicine diagnostic image to be described later.

This state is assumed to be the initial state. From this initial state, the top plate 68 is inserted into the 5PECT apparatus gantry 40 side by a distance Ml), and a 5PECT image or a Brehner image is photographed. Thereafter, the top plate 68 is pulled out by a distance g to return to the initial state.

Next, the top plate 68 is rotated by 180 degrees by the rotation mechanism 64. From this initial state, the top plate 68 is inserted into the magnetic resonance imaging apparatus gantry 20 side by a distance g', and an MR tomographic image is taken. Thereafter, the top plate 68 is pulled out by a distance p' and returned to the initial state.

The distance g in the above is 5PECT from the specific position of the top plate 68 in the initial state on the 5PECT device gantry 40 side.

Under the 80° rotation, the top plate 68 is slid based on the stored data (slide amount), thereby reproducing the photographing position.

Additionally, the present system may include an additional couch arrangement 80 located opposite the normal opening of the magnetic resonance imaging device gantry 20, or may be a dedicated couch for the magnetic resonance imaging device gantry 20. , are collectively controlled by the host computer 100 via the additional bed controller 88.

Next, the operation of the system of this embodiment configured as described above will be explained. That is, as shown in FIG. 1, the subject P is placed on the top plate 68 and is stationary, which is the initial state. From this initial state, set the top plate 68 to 5P.
Insert the distance M1 into the ECT device gantry 40 side, and
CT images or planar images can be taken. Thereafter, the top plate 68 is pulled out by a distance g to return to the initial state. Next, the top plate 68 is rotated by 180 degrees by the rotation mechanism 64.

Therefore, according to the system of this embodiment, it is possible to obtain an MR tomographic image and a 5PECT image of the same region without imposing a burden on the subject P and with high positioning accuracy. Then, as shown in FIG. 2(a), the monitor 1
It is possible to display two images on one display of 06, or to display an MR tomographic image and a 5PECT image separately and close to each other on two displays, making it easier for doctors and others to perform comparative diagnosis. .

Furthermore, since it is possible to take an MR tomogram and a 5PECT image of the same region, the MR tomogram and 5PECT image can be displayed on one display, as shown in Figure 2(b).
It is also possible to display the image in a superimposed manner with the ECT image. In this case, for example, by displaying the 5PECT image, which is functional information, in color, the diagnostic accuracy can be improved.

Furthermore, when the subject P is inserted into the 5PECT device gantry 40 and 5PECT images are being taken, the magnetic resonance imaging device gantry 20 is empty, so the additional bed device 80 is used to accommodate another patient. M R about
