    • A magnetic field intruding into an electron lens area from outside an X-ray image tube is detected by a magnetic field sensor. A magnetic field for offsetting the magnetic field is generated by a coil arranged in an input surface area of the X-ray image tube, so that the distortion is corrected by removing the effects of the magnetic field. The magnetic field sensor is arranged in an area surrounded by a magnetic shield of the X-ray image tube and constituting an outer peripheral area on the electron lens area side distant from the input surface area of the X-ray image tube. The magnetic field sensor is such that the effects of the magnetic field generated by the coil are reduced and the magnetic field intruding into the electron lens area is accurately detected.
    • 通过磁场传感器检测从X射线图像管外部侵入电子透镜区域的磁场。 通过设置在X射线图像管的输入表面区域中的线圈产生用于抵消磁场的磁场,从而通过去除磁场的影响来校正失真。 磁场传感器配置在由X射线图像管的磁屏蔽围绕的区域中,并且构成远离X射线图像管的输入面的电子透镜区域侧的外周区域。 磁场传感器使得由线圈产生的磁场的影响减小,并且能够精确地检测侵入电子透镜区域的磁场。
