    • Radiation image data obtained by an imaging unit in a radiation irradiation state is stored. Reference image data obtained by the imaging unit in a radiation non-irradiation state is stored. Reduced radiation image data and reduced reference image data as reduced image data of the radiation image data and the reference image data are generated. Offset correction processing is executed between the radiation image data and the reference image data. After output of the reduced radiation image data and the reduced reference image data to the external device is ended, offset-corrected radiation image data is output to an external device.
    • 存储通过成像单元在放射线照射状态下获得的辐射图像数据。 存储由成像单元在辐射非照射状态下获得的参考图像数据。 生成放射线图像数据和减少的参考图像数据,作为放射线图像数据和参考图像数据的缩小图像数据。 在放射线图像数据和参考图像数据之间执行偏移校正处理。 在减少的放射线图像数据的输出和缩小的参考图像数据到外部设备结束之后,偏移校正的放射线图像数据被输出到外部设备。

    • To efficiently generate image data by using correction data. First offset data is obtained in advance for each of a plurality of imaging times, and is stored in a second image storage unit. The imaging time requested by a user is selected from the plurality of imaging times by a control unit, and an object is shot in the selected imaging time so as to store image data in a first image storage unit. A correction processing unit offset-corrects the image data by using first offset data corresponding to the selected imaging time and outputs first image data (preview image). In parallel with an output of the first image data, an imaging operation without irradiation is performed to have second offset data on approximately the same condition as actual imaging obtained by the control unit, and the image data is offset-corrected by using the obtained second offset data so as to output second image data.
    • 通过使用校正数据有效地生成图像数据。 对于多个成像时间中的每一个,预先获得第一偏移数据,并存储在第二图像存储单元中。 通过控制单元从多个成像时间中选择用户请求的成像时间,并且在所选择的成像时间中拍摄对象,以将图像数据存储在第一图像存储单元中。 校正处理单元通过使用与所选择的成像时间对应的第一偏移数据来偏移校正图像数据,并输出第一图像数据(预览图像)。 与第一图像数据的输出并行地,执行没有照射的成像操作以在与由控制单元获得的实际成像大致相同的条件下具有第二偏移数据,并且通过使用获得的第二图像数据来对图像数据进行偏移校正 偏移数据,以便输出第二图像数据。

    • A fixed ring rail and a moving ring rail sandwiching a moving route of a radiation beam irradiating section therebetween, forms a cylindrical passage with a semicircular cross-section having a horizontal floor. Upon that passage is placed a moving floor composed of a continuous series of multiple plates which are connected freely flexible with each other. The moving floor is moved in synchrony with the rotation of radiation beam irradiation section, and, at the same time, the moving ring rail is allowed to rotate in the reverse direction by the same distance. A horizontal floor necessary as an access floor to the treatment bed and to the radiation beam irradiating section is formed regardless of the rotating position of the radiation beam irradiation section, and the patient is surrounded completely to remove him/her of fear.
