Generally, in the dentistry, an X-ray imaging apparatus capable of performing X-ray imaging is installed to treat teeth and various periodontal diseases, and to grasp the state of the teeth and alveolar bone for the purpose of correction of the dental heat.

An X-ray imaging apparatus used in a dentistry transmits a predetermined amount of X-rays to a part of a body part to be photographed, detects the intensity of the transmitted X-rays, converts it into an electric signal corresponding to the X- At this time, the computer acquires the image by obtaining the intensity of the X-ray of each point of the body imaging region and processing it.

As the above-described X-ray imaging apparatus, an X-ray imaging apparatus for CT (computerized tomography) capable of capturing a three-dimensional stereoscopic image and a panoramic X-ray imaging apparatus capable of imaging in two-dimensional plane are mainly used.

An X-ray imaging apparatus for CT is an imaging apparatus that displays a single-faced image of a body that can not be represented by a normal imaging. The X-ray is projected on a human body while rotating at a constant angle over 360 degrees. The transmitted X- And reconstructs the absorption value of the cross section of the human body to display the image.

In addition, the panoramic X-ray imaging apparatus is a device that can take a panoramic image so that the whole tooth condition and the jaw joint can be seen at a glance by taking an entire image in the circumferential direction around the X-ray generator.

The photographer grips the knob 17 at the time of photographing and fixes the jaw to the pedestal 18. The operator operates the touch LCD 19 to set the image photographing conditions and then photographs the examinee.

At this time, a laser beam for aligning the head of the examinee is used before the image capturing. Specifically, one laser beam for aligning the Frankfurter line with a panoramic image, a canine laser beam for aligning the canine, One vertical laser beam and one horizontal laser beam are used to center the FOV, and one facial laser beam commonly used for panoramic radiography and CT imaging.

In addition, more vertical alignment laser beams and horizontally aligned laser beams may be configured in the instrument to reflect the FOV size in CT mode.
