A medical image diagnosis apparatus according to one embodiment includes a gantry and a first light source. The gantry includes a first opening to which a subject is inserted. The first light source emits light capable of sterilization to the first opening.

Medical image diagnosis apparatus

A computed tomography apparatus capable of confirming the positional relationship of an imaging region and a field of view in a real space at the time of determining the position of the imaging region. The computed tomography apparatus according to an embodiment comprises a couch that moves a top board on which a subject is placed. A gantry comprises an opening into which a top board is inserted. A light projection part is provided in the gantry. A setting part sets a field of view with respect to the subject. A controller causes light indicating the set field of view to be projected by controlling the light projection part.

Computed tomography apparatus

A rotor is rotatably supported in a gantry housing having a substantially sealed structure. An X-ray tube is provided in the rotor. A cooler is provided in the rotor and cools a refrigerant within the X-ray tube. An X-ray detector is provided in the rotor. A reconstruction unit reconstructs an image on the basis of an output of the X-ray detector. A radiator is fixed inside the gantry housing at a position opposite to an exhaust opening of the cooler when the rotor is stationary.

X-ray computed tomographic apparatus

An X-ray CT apparatus, wherein a drum type rotation frame is rotatably supported by a fixed circular frame so as to surround an outer surface of the drum type rotation frame through a plurality of bearings provided between an inner surface of the fixing circular frame and an outer surface of the drum type rotation frame, for example in ring-like configuration. When the drum type rotation frame receives a large centrifugal acceleration due to a high speed rotation, outside expansion of the drum type rotation frame can be constrained due to both the rigidity of the fixed frame and the rigidity of the plurality of bearings provided on the outer surface of the rotation frame, thereby to maintain the relative positions of the X-ray tube and the X-ray detector and prevent deterioration of reconstructed images.

X-ray CT apparatus

An X-ray computed tomographic apparatus includes a cylindrical rotary base supported so as to be rotatable about a rotational axis, an X-ray tube unit mounted on the rotary base, an X-ray detecting unit mounted on the rotary base, and a reinforcing ring fixed to an end of the rotary base, and having a greater rigidity than the rotary base.

A permanent magnet type motor comprising a rotor main body rotatably supported with respect to a stationary member, a rotor which is provided on an outer periphery face of the rotor main body and which is arranged such that S poles and N poles of a plurality of permanent magnets are provided alternately, a stator composed of a stator core arranged at the outer periphery side or inner periphery side of the rotor, the stator core having winding storage sections, and stator windings stored in the winding storage sections, a sensor fixed to the stationary member so as to be proximal to the permanent magnets, the sensor detecting a position of the permanent magnets, a detection target member having a detector for detecting a magnetic resistance change portion formed on the rotor main body, and a rotational position detecting magnetic sensor arranged at the stationary member.
