ABSTRACT:
An X-ray imaging apparatus including an X-ray tube which emits X-rays, an image sensor which detects X-rays which pass through an object, a support arm which supports the X-ray tube and the image sensor so that they are opposed to each other across the object, a driving motor which moves the support arm in a predetermined direction, a gain adjustment circuit which adjusts the imaging sensitivity of the image sensor and a controlling circuit for controlling the gain of the adjusting circuit. The controlling circuit controls the gain adjusting circuit on the basis of the detected image density of the image sensor. When the adjustment by means of the gain adjusting circuit is insufficient, the controlling circuit controls X-ray tube current, X-ray tube voltage and driving speed adjusters.
