摘要： To a supporting frame having an opening portion used to insert a table for mounting thereon an object under examination along a horizontal direction, a rotary member rotated around the opening portion is mounted; and a medical X-ray apparatus is provided with a first supporting member supported by the rotation member, for supporting an X-ray tube apparatus which irradiates an X-ray to an object under examination; a second supporting member for supporting a detection apparatus for detecting a transmission X-ray of the object under examination, the second supporting member being supported by the rotary member and being arranged opposite to the X-ray tube apparatus; a rotation control apparatus for controlling a rotation of the rotary member; a control apparatus for setting an irradiation angle of said X-ray with respect to a body axial direction of the object under examination to an arbitrary irradiation angle, and also for arranging the detection apparatus opposite to the X-ray tube apparatus in correspondence with the set arbitrary irradiation angle; and an image processing apparatus for processing an output signal from the detection apparatus so as to produce both a two-dimensional image and a three-dimensional image. While these control apparatus and rotation control apparatus are controlled, both the X-ray tube apparatus and the detection apparatus are rotated around the object under examination. Alternatively, X-ray fluoroscopic operation is carried out along an arbitrary irradiation angle. An output signal derived from the detection apparatus is processed by an image processing apparatus so as to produce a two-dimensional image and/or a three-dimensional image. Then, the produced images are displayed on a display apparatus.

摘要： The rotary member carrying the X-ray radiation unfit and the X-ray detection unit and rotated around a subject is used as the rotor. The rotor is provided with a rotor core and a plurality of conductors connected to the core. The stator has at least one set of stator core and stator winding, the at least one set of stator core and stator winding being adapted to clamp the rotor and arranged at opposing positions. A three-phase AC current is supplied to the stator winding to generate a rotating magnetic field to rotate the rotor and thereby rotate the rotary member at high speed. Because the scan time can be reduced, the X-ray CT scanner can scan such moving organs as heart.
