Hand-grip type oral X-ray device having alignment function

A hand-grip type oral X-ray device having an alignment function, the hand-grip type oral X-ray device comprising:

• an X-ray tube configured to generate and emit X-rays;
• an X-ray receiver comprising a first gyro-sensor, first communication module, and a magnet positioned at a corner of the X-ray receiver, configured to generate a magnetic force, the X-ray receiver configured to receive the X-rays generated from the X-ray tube to acquire X-ray data about an object in an oral cavity;
• and
• a handle comprising a rod-shaped grip operable by a hand of a user and an extension arm connecting the X-ray receiver and the grip to each other, the handle coupled to the X-ray receiver,
• wherein the handle comprises:
• an image generating unit configured to process a radiographic image taken by the X-ray receiver through a radiographic image processing program to generate a radiographic image file in a form that can be visually ascertained by the user;
• a first display unit configured to display the radiographic image generated by the image generating unit;
• a memory unit configured to store the radiographic image taken by the X-ray receiver;
• and
• a power supply unit configured to supply power to the X-ray receiver and the handle, wherein the X-ray tube comprises:
• a second gyro-sensor;
• a Hall sensor configured to sense the magnetic force formed by the magnet;
• an ultrasonic sensor configured to sense the X-ray receiver by generating ultrasonic waves;
• and
• a proximity sensor configured to sense a distance between the X-ray tube and the X-ray receiver.
