Abstract
Disclosed herein is a panoramic X-ray photographing apparatus and a method for photographing using the same. The present invention relates to the panoramic X-ray photographing apparatus capable of conducting a panoramic photographing without generating X-ray in neck cervical vertebrae part employing a rotary arm driven in 3-axis direction. In case of scanning the neck cervical vertebrae part, a photographing can be conduct without X-ray. As a result, it is possible to prevent an image acquired by the neck cervical vertebrae part from being unclear. Also, an angle of incidence of X-ray at a photographing point can be controlled to be vertical, so that an image distortion phenomenon can be prevented. Furthermore, tempromandibular joint can be photographed at optimum enlargement ratio, thereby acquiring clear image.
