Medical imaging diagnosis apparatus, nuclear medicine diagnosis apparatus, X-ray CT apparatus, and bed apparatus

A medical imaging diagnosis apparatus comprising:

• a top-plate configured for a phantom 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 phantom;
• a storage configured to store a first deviation amount between 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;
• a processing circuitry configured to reconstruct a reconstruction image relating to the phantom, based on output data from the X-ray detector and to calculate, based on a second deviation amount between a third position indicative of a characteristic point of a region relating to the phantom in the reconstruction image and the first position, and on the first deviation amount, a distance and a direction from the third position to the second position;
• and
• a moving assembly configured to move 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, in accordance with the distance and the direction.

An X-ray CT apparatus capable of transmission/reception of data to/from a nuclear medicine diagnosis apparatus including a second gantry including a gamma ray detector configured to detect gamma rays emitted from a subject, the X-ray CT apparatus comprising:

• a transmitter/receiver configured to receive, from the nuclear medicine diagnosis apparatus, data relating to a second position indicative of a center position of an effective view field in the second gantry;
• a top-plate configured for the subject to be placed thereon;
• a first gantry including an X-ray generator and an X-ray detector which revolve around the top-plate;
• 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, the second position, 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.

A nuclear medicine diagnosis apparatus capable of transmission/reception of data to/from an X-ray CT apparatus including a first gantry including an X-ray generator and an X-ray detector which revolve around a subject, and 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, the nuclear medicine diagnosis apparatus comprising:

• a top-plate configured for the subject to be placed thereon;
• a second gantry including a gamma ray detector configured to detect gamma rays emitted from the subject;
• and
• a moving assembly configured to move, based on the first position, a second position indicative of a center position of an effective view field in the second gantry, and the third position, 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.

A bed apparatus capable of transmission/reception of data to/from a nuclear medicine diagnosis apparatus and an X-ray CT apparatus, comprising:

• a top-plate;
• a receiver configured to receive, from the nuclear medicine diagnosis apparatus, data relating to a first position indicative of a center position of an effective view field in a gantry of the nuclear medicine diagnosis apparatus, and to receive, from the X-ray CT apparatus, data relating to a second position indicative of a center position of an effective view field in a gantry of the X-ray CT apparatus;
• and
• a moving assembly configured to move the top-plate relative to the second position, based on the first position and the second position.
