摘要：
Disclosed is an X-ray image radiographing apparatus being economical by using a small width sensor, occupying less space, and providing an X-ray CT image and an X-ray panoramic image without distortion and with high accuracy. An X-ray image radiographing apparatus according the present invention includes a rotation supporter rotating based on a rotation shaft a generating unit including an X-ray generator radiating an X-ray beam a sensing unit including a small width sensor moving in a width direction thereof and a controller changing a rotation speed of the rotation supporter or a frame rate of the sensing unit to compensate changes in magnification ratio according to a distance change between an area of interest of the subject and the small width sensor when performing an X-ray image radiographing sequence obtaining a number of CT images by rotating the rotation supporter.
