Abstract
An X-ray image apparatus is formed of an X-ray irradiation device for irradiating X-ray to a subject with an observing area, and an X-ray image taking device for receiving the X-ray irradiated from the X-ray irradiation device and passing through the subject. The X-ray image taking device provides image signals of the X-ray passing through the subject. A support device is connected to the X-ray irradiation device and the X-ray image taking device for supporting and moving both devices around the subject. A calculating device is electrically connected to the X-ray image taking device for calculating a location of the observing area in the subject by image signals obtained from at least two different directions. The center of rotation for the X-ray irradiation device and the X-ray image taking device is adjusted to be the center of the observing area to thereby easily read the images from different directions.
