摘要： A small-sized high-precision superconducting magnet apparatus which can prevent an occurrence of the principal factor in generating a quench and can restrain the magnetic flux from varying with time, and a method of regulating the magnetization of such a superconducting magnet apparatus, by which the superconducting magnet apparatus can be uniformly magnetized. Superconducting magnet apparatus of the present invention has: a cooling container; a holding medium for holding a persistent current therein, which is placed in said cooling container and is operative to generate a magnetic flux in a uniform magnetic field region (FOV); static-magnetic-field generating means composed of a plurality of cylinders using superconducting composite plate materials; a cylinder supporting base for holding the plurality of cylinders; and temperature regulating devices (not shown in FIG. 67) embedded in the cylinders, respectively. Magnetization of the static-magnetic-field generating means is performed by induction-magnetizing. Further, the regulation of a magnetization value of the static-magnetic-field generating means is regulated by controlling the temperature of the cylinders by means of the temperature regulating devices.

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.
