Referring to FIG. 1A, the X-ray imaging apparatus 100 is a panorama, CT, and head measurement X-ray imaging apparatus, and includes a base 195, a support pillar 190, a lifting member 170, a panorama, and a CT imaging unit. 100a and a cephalometric photographing unit 100b, etc., and can perform panorama photographing, CT photographing, and head photographing photographing.

The base 195 supports the support pillar 190 on which the components are installed, and the support pillar 190 is installed on one side of the base 195.

The lifting member 170 is installed on the support pillar 190. The elevating member 170 is provided with a control motor, and can be moved up and down. Therefore, the height can be adjusted appropriately according to the height of the patient.

The panoramic and CT photographing unit 100a is installed on a front surface of the elevating member 170, and the head measurement photographing unit 100b is connected to one surface of the elevating member 170.

Looking at the panorama and CT imaging unit 100a in detail, the jaw support member 180 is connected to the lower portion of the elevating member 170 in a substantially vertical direction.

The rotary arm support member 150 is connected in an almost vertical direction to an upper portion of the elevating member 170. The rotary arm support member 150 supports the rotary arm 140 by the rotary arm driving means 160. Lines are formed on the rotary arm support member 150 so that the rotary arm driving means 160 can move (not shown in the drawing) to drive along the lines.

The rotary arm driving means 160 may be driven in the longitudinal direction of the rotary arm support member 150 (X-axis driving), and may be driven in the horizontal direction perpendicular to the X-axis driving (Y-axis driving). In addition, it can be rotated based on the central axis. That is, the rotary arm driving unit 160 drives the rotary arm 140 to perform CT or panoramic imaging. As will be described later, in the case of CT imaging, the rotary arm driving means 160 performs rotation by driving the rotary arm 140 based on a central axis, and in the case of panorama photography, the rotary arm 140 drives the X-axis, Shooting is performed by driving Y-axis and rotating. The rotary arm support member 150 and the elevating member 170 are provided with mechanical components such as a control motor for driving the rotary arm driving means 160. In addition, a rotary arm driving means control device for controlling the rotary arm driving means 160 to move the rotary arm 140 to a predetermined trajectory in accordance with CT or panoramic imaging. The mechanical description will be omitted since it is obvious to those skilled in the art.

The rotary arm 140 has an X-ray light source unit 110 connected to one end thereof, and an X-ray sensor unit 120 provided at the other end thereof, and is disposed to face each other.

The X-ray light source unit 110 generates X-rays and irradiates the patient, which is the object 130. The X-ray light source unit 110 is provided with an X-ray source and a collimator (collimator) to pass the generated X-rays through the object to irradiate the X-ray sensor unit 120.

The X-ray light source unit 110 may be driven separately from the rotation arm 140. That is, the X-ray light source unit driving means 115 is provided at a portion where the rotary arm 140 and the X-ray light source unit 110 are connected to move the X-ray light source unit 110. Therefore, the X-ray light source unit 110 may be horizontally driven in a direction closer to the X-ray sensor unit 120 or in a direction away from the X-ray sensor unit 120 separately from the rotation arm 140. In addition, in the case of head measurement imaging, the X-ray light source driving means 115 may perform the imaging by horizontally driving or tilting the X-ray light source 110 separately from the rotation arm 140. The rotating arm 140 is provided with mechanical components such as a control motor required for driving the X-ray light source unit 110.

Therefore, when CT imaging or panorama photography, the distance between the patient 130 and the X-ray light source 110 may be varied to adjust the magnification to perform imaging. A detailed description will be given below with reference to FIGS. 1B-1I.

The X-ray sensor unit 120 is an apparatus that receives X-rays and converts them into electrical signals. The X-ray sensor unit 120 detects X-rays generated by the X-ray light source unit 110 to acquire an image and then transmits the acquired image to the outside. The X-ray sensor unit 120 is fixed to the rotary arm 140 and has a sensor mounting unit 122 to which one sensor 121 is detached. The sensor 121 may be a panoramic sensor or a CT sensor. Accordingly, when performing CT imaging, the CT sensor may be selected and manually mounted on the sensor mounting unit 122 to perform CT imaging. When performing panoramic photography, the CT sensor may be mounted on the sensor mounting unit 122. After the separation, the panoramic sensor may be manually mounted on the sensor mounting part 122 to perform panorama shooting. In other words, the present invention uses a different sensor dedicated for each of panorama shooting or CT shooting.

The sensor mounting part 122 may have various shapes in addition to the groove shape disclosed in the embodiment of the present invention.

A second head fixing means 185 is positioned between the X-ray light source unit 110 and the X-ray sensor unit 120. The second head fixing means 185 has a headband shape surrounding the forehead of the patient, which is the object 130, and fixes the head of the patient. That is, it plays a role of fixing the head of the patient with the jaw support member 180.

Looking at the head measurement photographing unit 100b in detail, the horizontal arm 15 having the head measurement sensor unit 11, the collimator 14 and the first head fixing means 17 is connected by the connecting member 16. It is connected to one surface of the elevating member 170. The connecting member 16 is formed in a bar shape having a straight line to connect the horizontal arm 15 with the elevating member 170.

The horizontal arm 15 has a head measurement sensor unit 11 on one side thereof.

The head measurement sensor unit 11 is provided with a head measurement sensor mounting portion 12 from which the head measurement sensor 13 is detached, so that the head measurement sensor 13 can be mounted or detached manually.

The head measurement sensor 13 may use a line scan sensor such as a single line scan sensor or a multi line scan sensor. In this case, the panoramic sensor 121 may be used as the head measurement sensor 13. In this case, in the case of a line scan type sensor, a collimator 14 for converting X-rays into parallel rays is further required. Therefore, the collimator 14 may be provided on the other side of the horizontal arm 15 so as to face the head measurement sensor unit 11.

The horizontal arm 15 is provided with a first head fixing means 17 at a predetermined position to fix the object 18 that is the head of the patient.

Hereinafter, a method of performing CT imaging or panoramic imaging by varying the distance between the X-ray light source unit 110 and the X-ray sensor unit 120 will be described with reference to FIGS. 1B to 1I and a method of performing head measurement imaging. Let's do it.

A photographing method using the X-ray photographing apparatus 100 will be described with reference to FIG. 1B.

First, the object is placed at the photographing place (S1). In the case of panoramic or CT imaging, the patient, which is an object, is positioned in the second head fixing means 185, and in the case of head measurement, the patient, which is an object, is positioned in the first head fixing means 17. FIG.

Subsequently, the distance between the X-ray light source unit 110 and the X-ray sensor unit 120 included in the rotary arm 140 is varied according to the panoramic or CT imaging (S2).

In the case of the head measurement imaging, the distance between the X-ray light source unit 110 and the X-ray sensor unit 120 may be adjusted and may not be varied.

That is, the distance between the X-ray light source unit 110 and the X-ray sensor unit 120 may be adjusted by determining an optimal magnification ratio according to each of the panorama, CT, or head measurement imaging.

Subsequently, X-rays are irradiated onto the object to perform imaging (S3). That is, the panoramic imaging, the CT imaging or the head measurement imaging is performed by using the components of the X-ray imaging apparatus 100 appropriately.

1C to 1E, a panorama photographing and a CT photographing method will be described.

Referring to FIG. 1C, the head of the patient, which is the object 130, is positioned on the jaw support member 180 when the panorama is photographed, and the head of the object is fixed by the second head fixing means 185.

At this time, the X-ray sensor unit 120 is fixed to the rotary arm 140, but the X-ray light source unit 110 is not fixed to the rotary arm 140, the X-ray light source unit driving means 115 Can be moved separately by

The panoramic sensor 121 is mounted on the sensor mounting part 122 provided in the X-ray sensor unit 120. The panoramic sensor 121 may be a line scan sensor such as a single line scan sensor or a multi-line scanr.

Referring to FIG. 1D, the X-ray light source unit 110 is horizontally driven in a direction close to the X-ray sensor unit 120 using the X-ray light source unit driving means 115 to adjust the optimal magnification. .

The magnification means the ratio of the distance a between the object 130 and the X-ray light source unit 110 to the distance b between the X-ray sensor unit 120 and the X-ray light source unit 110. The larger this value is, the larger the image obtained. If the magnification is large, the amount of X-rays generated is not beneficial to the patient, and if the magnification is small, it is difficult to construct mechanically. Therefore, in order to obtain a good image while being easy to construct mechanically, it is desirable to perform photographing by selecting an optimal magnification.

In the case of the panorama shooting, the magnification is preferably adjusted from 1: 1.1 to 1: 1.6. Most preferably, panorama shooting with the magnification ratio of 1: 1.3 is most appropriate when viewed in terms of mechanical aspect or high definition image.

For example, the distance a 'between the object 130 and the X-ray light source unit 110 is 454 mm, and the distance b' between the X-ray sensor unit 120 and the X-ray light source unit 110. Adjust the to 590mm to adjust the magnification to about 1: 1.3. That is, the X-ray light source unit 110 is driven horizontally in a direction closer to the X-ray sensor unit 120 by using the X-ray light source unit driving means 115 to perform panorama photography.

Subsequently, after setting a central axis (x) at a predetermined position of the patient to be photographed, a rotation axis of the rotation arm 140 is set, and the rotation arm 140 is positioned along a predetermined trajectory of the rotation axis along the center axis. Follow the rotation drive to perform the shooting. At this time, the X-ray generated by the X-ray light source unit 110 is irradiated to the object 130, the X-rays passing through the object 130 is detected by the X-ray sensor unit 120 is photographed .

Referring to FIG. 1E, when performing CT imaging, the head of the patient, which is the object 130, is positioned on the jaw support member 180, and the head of the object 130 is fixed by the second head fixing means 185. Fix it. In this case, when CT imaging is performed after panoramic photography, the panoramic sensor 121 is separated from the sensor mounting unit 122, and then replaced by the CT sensor 121. The patient may be positioned after exchanging the CT sensor 121 in advance.

The CT sensor 121 may use an area sensor such as a single area sensor or a multi area sensor, or may use a sequential drive type sensor.

Subsequently, the X-ray light source unit 110 is horizontally driven in a direction away from the X-ray sensor unit 120 using the X-ray light source unit driving means 115 to adjust the optimal magnification.

At this time, the enlargement ratio is preferably adjusted from 1: 1.3 to 1: 2. In particular, when photographing the anterior part, it is most preferable to adjust the magnification ratio to 1: 1.6, and when photographing the posterior part, the magnification ratio is 1: 1.5.

For CT imaging of the anterior part of the patient, for example, the distance a ″ between the object 130 and the X-ray light source unit 110 is 424 mm, and the X-ray sensor unit 120 and the X-ray light source unit ( If you adjust the distance (b ″) to 678mm between 110), you can shoot with the magnification of about 1: 1.6.

For CT imaging the posterior part of the patient, for example, the distance a ″ between the object 130 and the X-ray light source unit 110 is 424 mm, and the X-ray sensor unit 120 and the X-ray light source unit ( By adjusting the distance (b ″) to 637mm, the user can take a picture with an enlargement ratio of about 1: 1.5.

Subsequently, a central axis x is set at a predetermined position of the patient to be photographed, and the rotation arm 140 is rotated about the central axis to perform imaging. At this time, the X-ray generated by the X-ray light source unit 110 is irradiated to the object 130, the X-rays passing through the object 130 is detected by the X-ray sensor unit 120 is photographed .

Various head measurement imaging methods will be described with reference to FIGS. 1F to 1I.

1F and 1G, a line connecting the X-ray light source unit 110 and the X-ray sensor unit 120 in the X-ray imaging apparatus 100 includes the head measurement sensor 11 and the X-ray light source unit. It is located on the same line as the line connecting 120.

First, the head of the patient, which is the object 130, is fixed to the head of the object 130 by the first head fixing means 17.

Subsequently, the X-ray light source unit 110 may be horizontally driven in a direction close to or far from the X-ray sensor unit 120 by using the X-ray light source unit driving means 115 to adjust the magnification. The magnification is approximately 1: 1 as the distance c between the object 18 and the X-ray light source unit 110 versus the distance d between the head measurement sensor unit 11 and the X-ray light source unit 110. . Therefore, the head measurement may be performed without varying the distance between the X-ray light source unit 110 and the X-ray sensor unit 120, but if the magnification is necessary, the X-ray light source unit 110 may be used to photograph. Can be.

Subsequently, the sensor 121 mounted on the sensor mounting part 122 of the X-ray sensor unit 120 is separated. That is, the sensor 121 is separated from the sensor mounting part 122 so that the X-ray sensor unit 120 does not detect the X-rays generated by the X-ray light source unit 110. Therefore, the X-ray beam, collimator 14 and the head measuring sensor 13 irradiated from the X-ray light source unit 110 are aligned in a straight line. In this case, the detaching of the sensor 121 may be performed at any stage before the photographing by radiating X-rays to be described later.

Subsequently, the head of the patient, which is the object 130, is scanned to perform head measurement. That is, the X-rays generated by the X-ray light source unit 110 are irradiated to the object 130, and the X-rays passing through the object 130 are detected by the head measurement sensor 13 to perform imaging.

As described above, in performing the head measurement, the head sensor can be aligned by separating the panoramic sensor or the CT sensor from the sensor mounting part 122, so that the head measurement can be performed simply.

In this case, the head sensor may be photographed by mounting the panoramic sensor used in the panoramic photographing to the head measuring sensor mounting part 12. The head measurement sensor 13 may use a line scan sensor.

Referring to FIG. 1H, a line connecting the X-ray light source unit 110 and the X-ray sensor unit 120 in the X-ray imaging apparatus 100 includes the head measurement sensor unit 11 and the X-ray light source unit 120. The same angle as the line connecting () is maintained.

First, the head of the patient, which is the object 130, is fixed to the head of the object 130 by the first head fixing means 17.

Subsequently, the X-ray light source unit 110 may be horizontally driven in a direction close to or far from the X-ray sensor unit 120 by using the X-ray light source unit driving means 115 to adjust the magnification. If necessary, the head measurement may be performed without varying the distance between the X-ray light source unit 110 and the X-ray sensor unit 120.

Subsequently, the X-ray light source unit 110 is separated from the rotary arm 140 so that the X-ray generated by the X-ray light source unit 110 is detected by the head measurement sensor. Drive horizontally in vertical direction. Therefore, the X-ray beam, collimator 14 and the head measurement sensor 13 irradiated from the X-ray light source unit 110-1 are aligned in a straight line. At this time, the step of horizontally driving the X-ray light source unit 110 in the direction perpendicular to the longitudinal direction of the rotary arm 140 may be performed at any stage before the step of irradiating X-rays to be described later to photograph.

Subsequently, the head of the patient, which is the object 130, is scanned to perform head measurement. That is, the X-rays generated by the X-ray light source unit 110 are irradiated to the object 130, and the X-rays passing through the object 130 are detected by the head measurement sensor 13 to perform imaging.

Referring to FIG. 1I, a line connecting the X-ray light source unit 110 and the X-ray sensor unit 120 in the X-ray imaging apparatus 100 includes the head measurement sensor 11 and the X-ray light source unit 120. It maintains a predetermined angle with the same line as the line connecting.

First, the head of the patient, which is the object 130, is fixed to the head of the object 130 by the first head fixing means 17.

Subsequently, the X-ray light source unit 110 may be horizontally driven in a direction close to or far from the X-ray sensor unit 120 by using the X-ray light source unit driving means 115 to adjust the magnification. If necessary, the head measurement may be performed without varying the distance between the X-ray light source unit 110 and the X-ray sensor unit 120.

Subsequently, the X-ray light source unit 110 is tilted in a predetermined direction separately from the rotating arm 140. That is, the X-ray light source 110 is tilted so that the X-ray generated by the X-ray light source 110 is detected by the head measurement sensor. Therefore, the X-ray beam, collimator 14 and the head measuring sensor 13 irradiated from the X-ray light source unit 110 are aligned in a straight line.
