    摘要: This invention has one object to provide a method of collecting calibration data in radiation tomography apparatus that allows reliable collection of calibration data with a wide detector ring. In order to achieve this purpose, in the method of collecting calibration data in radiation tomography apparatus according to this invention, the number of coincidence events is obtained while the phantom that emits annihilation gamma-ray pairs moves as to pass through an inner hole of the detector ring. Such configuration dose not need the phantom having a width equal or larger than the detector ring, and may realize reliable collection of calibration data. Moreover, it may be considered that annihilation gamma-ray pairs have been emitted in uniform property without depending on positions of the detector ring. As a result, calibration data that is more suitable for removal of a image artifact may be obtained.

    摘要: 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.

The inclined surfaces (11, 21) each have an upper inclined surface (11a, 21a) and a lower inclined surface (11b, 21b), and the lower inclined surfaces (11b, 21b) are steeper than the upper inclined surfaces (11a, 21a). The body (10) is fitted in and supported by the part (20) at the upper inclined surfaces (11a, 21a) and the lower inclined surfaces (11b, 21b). By this, the body is prevented from being wedged into the frame too deeply and also from becoming inclined with respect to the frame or riding up.
