    • Provided is a medical image diagnosis apparatus which requires a small area for installation, has a short length in an axial direction of the apparatus, can reduce a problem of the strength of a top plate, and can simultaneously carry out dynamic PET-imaging of the entire body. A top plate (61) on which an examinee lies is moved through a tunnel of a CT gantry (2) and a PET gantry (3) to execute CT imaging and PET imaging. A PET unit consisting of a plurality (e.g. seven) of PET units (32) has a length of 2 m in the axis direction, the visual field thereof covers the whole body and the whole body can be simultaneously subjected to dynamic PET-imaging. For the maintenance of the PET gantry (3), the diagnosis apparatus is separated at an arbitrary PET unit (32) to be maintained, the apparatus slides on a rail (31) in the axis direction and is separated for maintenance operation. Accordingly, a large space for maintenance is not required and the area for installation is small.

    • This invention has one object to provide radiation tomography apparatus that allows suppression of arithmetic load of detection data with a wider detector ring. In order to achieve this purpose, the radiation tomography apparatus according to this invention performs coincidence only when two scintillation counter crystals that detect gamma rays coincidentally (A) belong to the same ring unit, or (B) belong to each of the ring units adjacent to each other. Accordingly, a distance in the central axis direction between the radiation detecting elements is limited to be equal to or less than a thickness of the ring unit in the central axis direction. Accordingly, radiation tomography apparatus may be provided that allows generation of the sectional image suitable for diagnosis while arithmetic load is suppressed.
    • 本发明的一个目的是提供一种放射线断层摄影装置,其能够利用较宽的检测器环来抑制检测数据的算术负载。 为了达到这个目的,根据本发明的放射线断层摄影装置只有当两个同时检测伽马射线(A)的两个闪烁计数晶体属于相同的环单元时,或(B)属于相邻的每个环形单元 对彼此。 因此,辐射检测元件之间的中心轴方向的距离被限制为等于或小于环形单元在中心轴线方向上的厚度。 因此,可以提供放射线断层摄影装置,其允许在抑制运算负载的同时产生适于诊断的截面图像。

    • A grinder includes a housing, a gear cover attached to the housing by a plurality of screws, a spindle case attached to the gear cover, a wheel guard rotatably mounted on the spindle case for covering approximately a half of a disc-shaped tool bit attached to a spindle, a stop piece that regulates the rotation of the wheel guard. The wheel guard is selectively fixed to and unfixed from the spindle case. The stop piece is fixed to the housing together with the gear cover by at least one of the plurality of screws. The stop piece has an abutting section at which the stop piece abuts the wheel guard to regulate the rotation of the wheel guard. The abutting section is located at a position deviated from an axial line of the at least one of the plurality of screws.
