The present invention relates to an X-ray photographing apparatus and a photographing method using the same.

An X-ray imaging apparatus widely used in the medical technology field irradiates the human body with an X-ray to acquire an image of the inside of the human body. Through the analysis of acquired images, the inside of the human body is diagnosed and abnormalities are detected.

The principle of image generation of an X-ray imaging apparatus is that an X-ray generated from a generator that generates an X-ray is irradiated to an object to be photographed and a X-ray arriving at a part of the object or not is transmitted through a sensor facing the generator, The image is generated by converting the X-rays into electrical signals.

In recent years, various imaging methods using X-rays have been developed to acquire various images of the inside of the human body. Specifically, in relation to dental treatment, various images are acquired using CT (Computerized Tomography), Panoramic (Panoramic) and Cephalometric imaging methods and used for dental treatment.

For example, the CT X-ray photographing apparatus is a photographing method for acquiring a three-dimensional image and grasping the three-dimensional structure of the inside of the human body, thereby enabling the measurement of the structure of the alveolar bone, the location of the neural tube, and the bone density.

The panoramic photographing device is a method of performing tomographic photographing while rotating, and acquiring a whole image by attaching each image along a predetermined trajectory, thereby grasping the entire tooth condition and structure, and utilizing it for diagnosis and operation.

In addition, the cephalographing apparatus is a method for acquiring an image of the entire head region, in which a light source generating an x-ray and a subject are located at a relatively long distance and an image is acquired through a sensor positioned close to the subject. Obtaining an image of the entire head can be used to identify the shape of the head and teeth skeleton and skin, and to identify clinical location points.

The above-mentioned X-ray photographing apparatus uses X-rays in various ways according to the purpose of photographing. In recent years, a variety of photographing methods have been developed through a single apparatus.

This will be described in more detail with reference to FIG. 3 and FIG.

FIG. 3 is a view showing a case where the X-ray photographing apparatus of FIG. 1 is viewed from above. FIG. 4 is a view showing a case where the X-ray photographing apparatus of FIG. 2 is viewed from above.

Referring to FIG. 3, the X-ray imaging apparatus according to the present embodiment includes a first alignment unit 410 disposed between the first generator unit 110 and the sensor unit 200 for photographing in the first or second mode .

In this situation, when the first support part 310 and the sensor part 200 rotate and the second generator part 120 rotates for photographing in the third mode, a part of the first alignment part 410 is rotated by the second generator The X-ray irradiation unit 120 may be located within the irradiation area of the X-ray beam.

That is, in the first mode, since the first image generating unit 110 and the sensor unit 200 are rotated to acquire the panoramic image, the partial image must be generated in consideration of the predetermined trajectory, 2 < / RTI > mode.

For example, if it is desired to acquire a panoramic image, it is necessary that the focus according to the first mode corresponds to the arch path of the subject, or the partial image generated according to the first mode is attached according to the arch path, In order to calculate the accurate arch trajectory, a three-dimensional CT image can be used.

At this time, when the CT image is acquired, the second active region 220 of the sensor unit 200 may be set as an active region and a CT image may be generated in order to grasp the trajectory of the subject's dacryocysteine have.

In addition, the control unit controls the operation of the first moving member (not shown) or the third moving member (not shown) during photographing of the first mode according to the trajectory determined through the analysis of the CT image according to the second mode It is also possible.
