Disclosed is an X-ray image capture apparatus that can economically provide not only an X-ray CT image but also an undistorted accurate X-ray panoramic image using a small width sensor. An X-ray image capture apparatus according to an aspect of the present invention comprises: a rotary support rotating about a rotary shaft; a generator unit disposed on one side of the rotary support and including an X-ray generator irradiating an X-ray beam; a sensor unit disposed on an opposite side of the rotary support to face the generator unit with an object-to-be-examined therebetween and including a small width sensor moving in the width direction perpendicular to the rotary shaft while the rotary support is rotating; and a control unit varying the rotational speed of the rotary support or the frame rate of the sensor unit in order to compensate for a magnification change depending on a change in the distance between a portion of interest of the object-to-be-examined and the small width sensor during an X-ray image capture sequence for acquiring a plurality of transmission images with the rotation of the rotary support.
