摘要： A magnetic circuit suitable for a self-held type rotary solenoid while maintaining properties, reducing cost, e.g., a material cost, and making the rotary solenoid smaller in size is provided. The rotary solenoid includes a swing yoke to which two magnets are fixed and a fixed yoke including projection portions at opposite sides thereof. An electromagnetic coil including a major magnetic pole is arranged at a center of the fixed yoke. The rotary solenoid is arranged to define a magnetic circuit extending through one of the magnets, the major magnetic pole, the fixed yoke, the projection portion, and the other magnet at a shortest distance. Therefore, even if a magnet made of a material having a low grade is used, it is possible to maintain sufficient magnetic properties.

摘要： A gantry defines an opening, and a surface coil is mounted in a predetermined position inside the opening. In tomography using this MRI apparatus, an examinee supported on a top board is moved into the opening. At this time, the top board is movable without being obstructed by the surface coil. The surface coil receives NMR signals from a photographed site lying directly over the surface coil. Sectional images are prepared based on the NMR signals received. When shifting the site to be photographed, the operator in a scanner control room gives an instruction to move the top board, thereby adjusting a photographing position. It is unnecessary for the examinee to move on the top board, or for the operator to move from the scanner control room to the photographing room. The examinee entering the gantry opening is illuminated by light from a light projector. A position of the top board when the light illuminates the site to be photographed is regarded as a starting point. The top board is moved from the starting point by a distance between the light projector and surface coil. This achieves an accurate positional adjustment between the site to be photographed and the surface coil.
摘要翻译： 台架限定开口，并且表面线圈安装在开口内的预定位置。 在使用该MRI装置的断层摄影中，将支撑在顶板上的受检者移动到开口中。 此时，顶板可移动而不受表面线圈的阻碍。 表面线圈从直接位于表面线圈上方的拍摄部位接收NMR信号。 基于收到的NMR信号制备截面图像。 当移动要拍摄的场所时，扫描仪控制室中的操作者给出移动顶板的指令，从而调整拍摄位置。 受试者无需在顶板上移动，或者让操作者从扫描仪控制室移动到拍摄室。 进入龙门开口的受试者被来自投影仪的光照亮。 当照明照明场所时顶板的位置被认为是起点。 顶板从起点移动光源与表面线圈之间的距离。 这实现了要拍摄的部位与表面线圈之间的精确的位置调整。
