The present invention relates to a subject head alignment apparatus, a subject head alignment method, and a computer-readable recording medium.

An X-ray imaging apparatus that is widely used in the medical technology field irradiates an X-ray onto a human body and acquires an image of the inside of the human body. Through this, abnormalities inside the human body are detected.

In particular, among the X-ray imaging devices, the panoramic imaging device mainly used in dentistry can generate images of teeth and alveolar bones, which are the object of image generation, on a single two-dimensional plane, so that the prognosis of orthodontic treatment is determined and the state of eruption of teeth. It is usefully used for various diagnostic purposes such as confirmation and alveolar bone height. In addition, among the X-ray imaging devices, the dental CT imaging device is of great help in grasping the state of anatomical structures such as the thickness of the alveolar bone and the location of major nerves for implant procedures.

In this way, an X-ray imaging device used for diagnostic purposes in dentistry is a sensor that generally irradiates an X-ray generated from a generator, and passes an X-ray that partially or does not pass through the body of the examinee and faces the generator. It receives light through. Then, the received X-rays are converted into electrical signals to obtain projection data. In particular, such an X-ray imaging apparatus may generate an electrical signal necessary for generating X-ray image data by continuously irradiating and receiving X-rays while rotating the generator and the sensor around a rotation axis.
