The top-plate places a subject thereon. The bed supports the top-plate. The first gantry includes an X-ray generator and an X-ray detector which revolve around the top-plate. The second gantry includes a gamma ray detector which detects gamma rays emitted from the subject. The moving assembly moves, based on a first position indicative of a center position of an effective view field in the first gantry and a second position indicative of a center position of an effective view field in the second gantry, the top-plate relative to the second position. ## Claims ### Claim 1 A medical imaging diagnosis apparatus comprising: a top-plate configured for a subject to be placed thereon; a bed configured to support the top-plate; a first gantry including an X-ray generator and an X-ray detector which revolve around the top-plate; a second gantry including a gamma ray detector configured to detect gamma rays emitted from the subject; a processing circuitry configured to reconstruct a reconstruction image including a characteristic point of the subject, based on output data from the X-ray detector; and a moving assembly configured to move, based on a first position indicative of a center position of an effective view field in the first gantry, a second position indicative of a center position of an effective view field in the second gantry, and a third position indicative of a position of the characteristic point, the top-plate to a position where the third position relative to the first position agrees with the second position relative to the first position. ### Claim 2 (depends on 1) The medical imaging diagnosis apparatus of claim 1, wherein the moving assembly is configured to move the top-plate, after an end of imaging of the subject by the first gantry and before a start of imaging of the subject by the second gantry. ### Claim 3 A medical imaging diagnosis apparatus comprising: a top-plate configured for a phantom to be placed thereon;
