The X-ray generator 1 generates X-rays, which are electromagnetic waves having a short wavelength and strong transmittance when high-speed electrons collide with an object. The X-ray generator 1 may include a filament that emits hot electrons and an electrode that forms a strong electric field with a high voltage.

When a high voltage generated by the high voltage supply is applied to the X-ray generator 1, hot electrons are emitted from the filament forming the cathode. The released hot electrons drift by a strong electric field and then collide with the anode, and X-rays are generated at the point of the local size where the hot electrons collide. In FIG. 2, a portion marked by s represents a point of a local size where X-rays are generated due to collision of hot electrons.

An X-ray irradiation area control unit 10 is disposed in front of the X-ray generation unit 1, and the X-ray generation unit 1 has an X-ray irradiation path and irradiation therein so that X-rays are irradiated to the X-ray irradiation area control unit 10. It may include an aperture 6 capable of adjusting the area.

The stop 6 may be made of a material capable of attenuating X-rays, such as lead or tungsten, but is not limited thereto.

The aperture 6 may operate in a manner that adjusts the area to which X-rays are irradiated in a circular shape like the aperture of a camera.

Alternatively, a pair of members made of a material capable of attenuating X-rays are symmetrically arranged left and right with respect to the central axis of X-ray irradiation, and move in the x-axis direction, that is, left and right, and the other pair of members is based on the central axis of X-ray irradiation. It may be symmetrically arranged up and down to move in the y-axis direction, that is, vertically, while adjusting the area to which X-rays are irradiated into a square shape. The method of adjusting the aperture 6 is only an example and is not limited thereto.

In this way, the X-rays generated by the X-ray generator 1 are irradiated to the X-ray irradiation area control unit 10 disposed in front of the X-ray generator 1 by adjusting the irradiation path and the irradiation area by the diaphragm 6.

The X-ray irradiation area adjusting unit 10 includes a stop 7 that can adjust an irradiation path and an irradiation area of X-rays. As described above, the diaphragm 7 may adjust the irradiation path and the irradiation area of the X-ray in the same manner as the diaphragm 6 provided inside the X-ray generator 1.

The camera 20 is mounted outside the X-ray irradiation area control unit 10 so as to photograph the object 3 in the direction in which the X-rays are irradiated.

Preferably, the X-ray irradiation area control unit 10 may be mounted on the outside of an end where X-rays are emitted to the outside so that the entire shape of the object 3 can be photographed.

When the object 3 is photographed by the camera 20, the image 42 of the object is displayed on the display unit 30.

The camera 20 may photograph the entire shape of the object or a partial shape of the object by adjusting the photographing range. When the entire shape of the object is captured, an image of the overall shape of the object is displayed on the display unit 30, and when the partial shape of the object is captured, the image of the shape of the object is displayed on the display unit 30.

The detector 2 is a device that detects the amount of transmission of X-rays irradiated by the X-ray irradiation area control unit 10 through the object 3, and displays the internal state of the object 3 as an image by detecting the amount of transmission of X-rays. do.

The detector 2 may include a thin film transistor array substrate and an optical sensor.

The display unit 30 provides a user interface 40 for outputting various information related to X-ray imaging to a user of the X-ray apparatus so that X-ray imaging of the object 3 can be performed more easily.

The display unit 30 may use a touch screen so that accurate X-ray imaging is performed with only a simple touch gesture of a user. The user may select an imaging area through the user interface 40, adjust an X-ray irradiation area, and know how much X-rays are irradiated to the object 3 according to the size of the X-ray irradiation area. A detailed description of the user interface 40 will be described later.

3 is a block diagram showing the configuration of an X-ray apparatus according to an embodiment of the present invention, and FIG. 4 is a view showing a user interface 40 provided to the display unit 30 according to an embodiment of the present invention.

The camera 20 photographs the object 3.

The photographing of the object 3 is performed to inform the user of the X-ray irradiation region by overlapping and displaying the X-ray irradiation region on the image 42 of the object on the display unit 30. Therefore, the user's manipulation prior to full-scale X-ray photographing By means of, the object 3 is photographed first.

When the object 3 is photographed, the camera 20 converts image information of the object 3 into a digital signal and transmits it to the controller 50. As described above, since the camera 20 is mounted outside the X-ray irradiation area adjusting unit 10, the entire shape of the object can be photographed.

The input unit 21 is a means through which a user of the X-ray apparatus can input various commands for overall manipulation of X-ray imaging. The user may input a 　 command for X-ray photographing through the input unit 21 to control the overall progress of X-ray photographing. The input unit 21 may include a remote controller 22, a mouse 23, a keyboard 24, a voice recognition device 25 　, and a motion recognition device 26 　.

When the controller 50 receives the image signal of the object 3 transmitted from the camera 20, the control unit 50 controls the operation of the display unit 30 to display the image 42 of the object on the display unit 30 Is output to the display unit 30.

In addition, when various commands for X-ray imaging are input through the input unit 21, the control unit 50 provides X-rays such as the display unit 30, the X-ray irradiation area control unit 10, and the X-ray generation unit 1 according to the input command. It controls the operation of each component of the device.

The display unit 30 displays the image 42 of the object on a region of the user interface 40 according to a signal transmitted from the control unit 50.

The X-ray generator 1 adjusts the amount of X-ray irradiation or the operation of the aperture 6 according to the control signal transmitted from the control unit 50, and the X-ray irradiation area control unit 10 is transmitted from the control unit 50. The operation of the diaphragm 7 is adjusted according to the control signal.

Referring to FIG. 4, it can be seen that the user interface 40 is divided into a plurality of areas displaying different information, and the image 42 of the object is displayed on the first area 41 of the plurality of areas. In addition, the image 42 of the object may be displayed to identify the object 3 in the fifth area 48 in which basic information of the object 3 such as personal information of the object 3 and a disease record is displayed.

Here, each area of the user interface 40 will be described. Since the numbers assigned to each area are only arbitrary, they will be described regardless of the order of the numbers.

In the third area 47, a list of areas where X-rays are taken is displayed. For example, assuming that the subject (3) is a patient, a list of each body part such as head, chest, stomach, arm, and lower body is displayed, and if you select any one of these lists, a more detailed list of photographing sites Information on the photographing site can be displayed in this display format.

The information on the photographing site may be displayed in text or in the form of an icon symbolizing the features of each part. However, this is only an example, and it goes without saying that other methods may be used as long as the information on the photographing area is displayed. As described above, the user selects the photographing region by touching the desired photographing region from the list of photographing regions displayed as described above, or the remote controller 22, mouse 23, keyboard 24, voice input device 25, and motion recognition device. The photographing area may be selected through the input unit 21 including 26. Hereinafter, a user's command input through a touch will be described as an example.

An image 42 of an object and an X-ray irradiation area 43 are displayed in the first area 41. The X-ray irradiation area 43 is superimposed on the image 42 of the object, and the X-ray irradiation area 43 is displayed on an area corresponding to the corresponding imaging area when an imaging area is selected in the third area 47.

For example, when the neck is selected as the imaging area, the X-ray irradiation area 43 is displayed on the neck of the object in a rectangular shape. The X-ray irradiation area 43 may be input in advance by being set to cover a predetermined area including the corresponding imaging area for each imaging area.

The outline shape of the X-ray irradiation area 43 may be circular or polygonal, but it is preferable to have a rectangular shape. The user may adjust the size and position of the X-ray irradiation area 43 displayed on the first area 41 according to a predetermined touch gesture. That is, the size and position of the X-ray irradiation area 43 may be adjusted by touching and dragging. Since the detailed description of the X-ray irradiation area control is overlapped with the description of the second area 44 described later, it will be replaced in the description of the second area.

When the imaging area is selected in the third area 47 and the X-ray irradiation area 43 is displayed on the first area 41 by overlapping the image 42 of the object, the second area 44 does not display the object image. Only the X-ray irradiation area 45 is separately displayed.

The X-ray irradiation region 45 displayed in the second region 44 may be displayed in an enlarged form than the X-ray irradiation region 43 displayed in the first region 41, and may be displayed together with a scale indicating the size. have. This is to allow the user to more easily adjust the X-ray irradiation area.

The user irradiates X-rays to be irradiated to the object by adjusting the X-ray irradiation area 43 displayed in the first area 41 or adjusting the X-ray irradiation area 45 displayed in the second area 44 according to preference or convenience. You can adjust the area.

The user may adjust the size and position of the X-ray irradiation area 45 displayed on the second area 44 according to a predetermined touch gesture. That is, the size and position of the X-ray irradiation area 45 may be adjusted by touching and dragging.

When the size and position of the X-ray irradiation area 45 in the second area 44 are changed by a touch gesture, the X-ray irradiation area 43 of the first area 41 is also superimposed on the image 42 of the object. The size and position will change.

That is, the X-ray irradiation region 43 displayed in the first region 41 overlapping with the image 42 of the object is changed in association with the change of the X-ray irradiation region 45 displayed in the second region 44, through which the user The X-rays are irradiated to allow more precise and fine adjustment of the imaging area of the object 3 on which the image is taken.

Conversely, when the X-ray irradiation area 43 displayed on the first area 43 is adjusted, it goes without saying that the X-ray irradiation area 45 displayed on the second area 44 is interlocked therewith.

5 is a diagram illustrating that the size, location, and shape of an X-ray irradiation area displayed on the second area 44 are adjusted according to a predetermined touch gesture.

In FIG. 5, a single circle filled with black indicates a point where a touch is made, and a single circle filled with black indicates a predicted point where a single circle filled with black where the touch is made is dragged. The arrow indicated by the broken line indicates the path of movement, and the double circle with one larger circle around the single circle filled in black indicates the point where the double touch is made.

5A shows an example of a touch gesture for moving the X-ray irradiation area 45. The user may move the X-ray irradiation area 45 to a desired point by touching and dragging an arbitrary point inside the X-ray irradiation area 45.

5B, C, and D show an example of a touch gesture for changing the size of the X-ray irradiation area 45.

As shown in FIG. 5B, the user may adjust the size of the X-ray irradiation area 45 by touching and dragging an arbitrary point on one side of the X-ray irradiation area 45. By touching an arbitrary point on one side of the X-ray irradiation area 45 and dragging toward the facing side (a direction), the size of the X-ray irradiation area 45 can be reduced, and the opposite side (b direction) of the facing side ), the size of the X-ray irradiation area 45 may be enlarged.

In addition, as shown in FIG. 5C, the user may adjust the size of the X-ray irradiation region 45 by touching and dragging arbitrary points on two sides facing each other of the X-ray irradiation region 45. By touching and dragging an arbitrary point on the two opposite sides of the X-ray irradiation area 45 to the opposite side (c direction), the size of the X-ray irradiation area 45 can be reduced, and the opposite side of the facing side By dragging in the direction (d), the size of the X-ray irradiation area 45 may be enlarged.

In addition, as shown in FIG. 5D, the user may adjust the size of the X-ray irradiation area 45 by touching an arbitrary vertex of the X-ray irradiation area 45 and dragging in a diagonal direction. By touching an arbitrary vertex of the X-ray irradiation area 45 and dragging toward the opposite diagonal vertex (e-direction), the original shape of the X-ray irradiation area 45 can be maintained and only its size can be reduced. When dragging toward the direction (f direction), only the size of the X-ray irradiation area 45 can be maintained while expanding its size. As described above, the touch gestures shown in FIGS. 5B, 5C, and 5D are only examples of touch gestures capable of adjusting the size of the X-ray irradiation area 45, and other touch gestures may be used to implement the same function. Of course.

5E and 5F show an example of a touch gesture for rotating the X-ray irradiation area 45.

As shown in FIG. 5E, the user rotates the X-ray irradiation area 45 by touching an arbitrary vertex of the X-ray irradiation area 45 twice in a row and dragging the X-ray irradiation area 45 in the direction in which it is desired to rotate. I can make it. At this time, the X-ray irradiation area 45 only rotates in place and does not move.

In addition, as shown in FIG. 5F, the user touches an arbitrary vertex of the X-ray irradiation area 45 and an arbitrary point inside the X-ray irradiation area 45 in the direction in which the X-ray irradiation area 45 is to be rotated. The X-ray irradiation area 45 may be rotated by dragging. As in FIG. 5E, at this time, the X-ray irradiation area 45 only rotates in place and does not move. As described above, the touch gesture illustrated in FIGS. 5E and 5F is only an example of a touch gesture for rotating the X-ray irradiation area 45, and other touch gestures may be used to implement the same function.

5G and 5H show an example of a touch gesture for initializing the X-ray irradiation area 45 to a state before its size, position, and shape are deformed.

As shown in FIG. 5G, when a user touches three arbitrary points inside the X-ray irradiation area 45 at the same time, the X-ray irradiation area 45 is initialized before its size, position, and shape are changed.

In addition, as shown in FIG. 5H, when the user touches a certain point inside the X-ray irradiation area 45 and drags it in an arbitrary direction and drags it in the opposite direction to that direction, the size of the X-ray irradiation area 45, It is initialized before the location and shape are transformed. The drawing shows that the X-ray irradiation area 45 is shaken left and right, but this is only an example, and is initialized when the X-ray irradiation area 45 is shaken irrespective of the top, bottom, left and right.

Returning to the description of FIG. 4 again.

In the fourth area 46, the size of the X-ray irradiation area and the estimated amount of X-ray irradiation are displayed accordingly. The size of the X-ray irradiation area may be determined for each imaging area of the object 3 through data on an area mainly photographed at the corresponding imaging area.

The amount of X-ray irradiation according to the size of the X-ray irradiation area may be determined by using the amount of X-rays irradiated during general X-ray imaging, and calculating an X-ray amount that varies depending on the size of the X-ray irradiation area.

For example, when the chest is selected as the X-ray imaging area, the fourth area 46 displays a list of the imaging area and the amount of X-ray irradiation corresponding thereto.

In addition, the amount of X-ray irradiation that changes as the X-ray irradiation area is adjusted is displayed in real time. Through this information, the user can roughly know how much X-rays are irradiated to the object 3 according to the area of the X-ray irradiation region, and may adjust the size of the X-ray irradiation region by referring to this information. For example, when it is determined that the amount of X-rays expected to be irradiated to the selected X-ray irradiation area is large, the user can reduce the amount of X-ray irradiation by reducing the X-ray irradiation area.

Information on the object 3 is displayed in the fifth area 48. Assuming that the object 3 is a patient, information such as the patient's personal information and disease record is displayed so that the user can refer to the X-ray image. It goes without saying that the arrangement of each region shown in FIG. 4 is only an example and may have different arrangements.

6 is a flowchart illustrating a method of adjusting an X-ray irradiation area of an X-ray apparatus according to an embodiment of the present invention.

Referring to FIG. 6, when an object 3 is captured by the camera 20, the controller 50 displays an image 42 of the object on the display unit 30 (100 ).

When the object 3 is photographed, the camera 20 converts image information of the object 3 into a digital signal and transmits it to the controller 50, and the controller 50 transmits the object 3 transmitted from the camera 20. When the image signal of) is received, a signal for controlling the operation of the display unit 30 is output to the display unit 30 to display the image 42 of the object on the display unit 30. The display unit 30 displays the image 42 of the object on the first area 41 of the user interface 40 according to the signal transmitted from the control unit 50. When the image 42 of the object is displayed on the display unit 30, the controller may further separately display an X-ray irradiation area that can guide adjustment of the X-ray irradiation area.

When the image 42 of the object is displayed on the user interface 40 of the display unit 30, the controller 50 displays the X-ray irradiation area 43 by overlapping the image 42 of the object (110).

After the image 42 of the object is displayed on the user interface 40 of the display unit 30, when information on the photographing region of the object 3 is input, the controller 50 irradiates X-rays to the region corresponding to the photographing region. Areas 43 are overlapped and displayed. The X-ray irradiation area 43 may be input in advance by being set to cover a predetermined area including the corresponding imaging area for each imaging area.

The controller 50 separately displays only the X-ray irradiation area 45 on the second area 44 of the user interface 40 of the display unit 30 (120 ). When the image 42 of the object and the X-ray irradiation area 43 are overlapped and displayed on the first area 41 of the user interface 40 of the display unit 30, the image 42 of the object is displayed on the second area 44. Only the X-ray irradiation area 45 is separately displayed without displaying.

When the X-ray irradiation area 45 is displayed on the second area 44 of the user interface 40 of the display unit 30, the control unit 50 may be used in advance in the X-ray irradiation area 45 displayed on the second area 44. It is determined whether a predetermined touch gesture is detected (130).

The size and position of the X-ray irradiation area 45 displayed on the second area 44 change according to a predetermined touch gesture. That is, the user may adjust the X-ray irradiation area 45 to a desired size and position according to a predetermined touch gesture.

When a predetermined touch gesture is detected in the X-ray irradiation region 45 displayed on the second region 44, the controller 50 displays the X-ray irradiation region 45 modified according to the corresponding touch gesture on the second region 44 Do (140).

When the touch gesture described above in the description of FIG. 5 is input from the outside, the controller 50 determines whether the corresponding touch gesture matches a predetermined touch gesture, and if the touch gesture matches the size of the X-ray irradiation area 45 and Display by adjusting the position. When the size and position of the X-ray irradiation area 45 in the second area 44 are changed by a touch gesture, the X-ray irradiation area 43 of the first area 41 is also superimposed on the image 42 of the object. The size and position will change. That is, the X-ray irradiation region 43 displayed in the first region 41 overlapping with the image 42 of the object is changed in association with the change of the X-ray irradiation region 45 displayed in the second region 44, through which the user The X-ray is irradiated to allow more precise and fine adjustment of the imaging area of the object 3 on which the image is taken. In the above, the control of the X-ray irradiation area 45 displayed on the second area 44 has been described as an example. Conversely, the X-ray irradiation area 43 displayed on the first area 43 may be adjusted or the first area It goes without saying that when the X-ray irradiation area 43 displayed on 43 is adjusted, the X-ray irradiation area 45 displayed on the second area 44 is interlocked therewith.

When the X-ray irradiation region 45 displayed on the second region 44 changes according to a predetermined touch gesture, the controller 50 causes the X-ray irradiation region to be irradiated to the object 3 to be displayed on the second region 44. The X-ray irradiation area control unit 10 is controlled to match the X-ray irradiation area 45 (150).

The controller 50 outputs a signal for controlling the X-ray irradiation area control unit 10 to the X-ray irradiation area control unit 10 and controls the operation of the aperture 7 of the X-ray irradiation area control unit 10, The X-ray irradiation area irradiated to the object 3 is adjusted to match the X-ray irradiation area 45 deformed in the second area 44.

Since the touch gesture may be continuously performed until the desired X-ray irradiation area is formed, the controller 50 performs steps 130 to 150 until no touch gesture is detected in the X-ray irradiation area 45 of the second area 44. Repeat.

In step 130, if a predetermined touch gesture is no longer detected in the X-ray irradiation region 45 displayed on the second region 44, it is determined that the adjustment of the X-ray irradiation region 45 is completed, and the control process is completed.

7 is a flowchart illustrating a method of displaying an X-ray image according to an exemplary embodiment of the present invention.

Referring to FIG. 7, when an object 3 is photographed by the camera 20, the controller 50 displays an image 42 of the object on the display unit 30 (200 ).

When the object 3 is photographed, the camera 20 converts image information of the object 3 into a digital signal and transmits it to the controller 50, and the controller 50 transmits the object 3 transmitted from the camera 20. When the image signal of) is received, a signal for controlling the operation of the display unit 30 is output to the display unit 30 to display the image 42 of the object on the display unit 30. The display unit 30 displays the image 42 of the object on the first area 41 of the user interface 40 according to the signal transmitted from the control unit 50.

The controller 50 displays a list of photographing areas of the object on the display unit 30 (210).

In the third area 47 of the user interface 40 of the display unit 30, a list of photographing areas where X-ray imaging is performed is displayed. For example, assuming that the subject (3) is a patient, a list of each body part such as head, chest, stomach, arm, and lower body is displayed, and if you select any one of these lists, a more detailed list of photographing sites Information on the photographing site can be displayed in this display format.

The information on the photographing site may be displayed in text or in the form of an icon symbolizing the features of each part. However, this is only an example, and it goes without saying that other methods can be used as long as the information on the photographing area is displayed.

The controller 50 superimposes and displays the X-ray irradiation area 43 on the image 42 of the object (220).

After the image 42 of the object is displayed on the user interface 40 of the display unit 30, when information on the photographing region of the object 3 is input, the controller 50 irradiates X-rays to the region corresponding to the photographing region. Areas 43 are overlapped and displayed. The X-ray irradiation area 43 may be input in advance by being set to cover a predetermined area including the corresponding imaging area for each imaging area.

The controller 50 separately displays only the X-ray irradiation area 45 on the second area 44 of the user interface 40 of the display unit 30 (230 ). When the image 42 of the object and the X-ray irradiation area 43 are overlapped and displayed on the first area 41 of the user interface 40 of the display unit 30, the image 42 of the object is displayed on the second area 44. Only the X-ray irradiation area 45 is separately displayed without displaying.

The control unit 50 displays the expected amount of X-ray irradiation when the X-ray is irradiated on the fourth area 46 of the user interface 40 of the display unit 30 (240).

In the fourth area 46, the size of the X-ray irradiation area and the estimated amount of X-ray irradiation are displayed. It can be decided through.

The amount of X-ray irradiation according to the size of the X-ray irradiation area may be determined by using the amount of X-rays irradiated during general X-ray imaging, and calculating an X-ray amount that varies depending on the size of the X-ray irradiation area.

In addition, the amount of X-ray irradiation that changes as the X-ray irradiation area is adjusted is displayed in real time. Through this information, the user can roughly know how much X-rays are irradiated to the object 3 according to the area of the X-ray irradiation region, and may adjust the size of the X-ray irradiation region by referring to this information. For example, when it is determined that the amount of X-rays expected to be irradiated to the selected X-ray irradiation area is large, the user can reduce the amount of X-ray irradiation by reducing the X-ray irradiation area.

The control unit 50 displays information on the object 3 in the fifth area 48 of the user interface 40 of the display unit 30 (250).

Assuming that the object 3 is a patient, information such as the patient's personal information and disease record is displayed so that the user can refer to the X-ray image.

When the X-ray irradiation area 45 is displayed on the second area 44 of the user interface 40 of the display unit 30, the control unit 50 may be used in advance in the X-ray irradiation area 45 displayed on the second area 44. It is determined whether a predetermined touch gesture is detected (260).

The size and position of the X-ray irradiation area 45 displayed on the second area 44 change according to a predetermined touch gesture. That is, the user may adjust the X-ray irradiation area 45 to a desired size and position according to a predetermined touch gesture.

When a predetermined touch gesture is detected in the X-ray irradiation region 45 displayed on the second region 44, the controller 50 displays the X-ray irradiation region 45 modified according to the corresponding touch gesture on the second region 44 Do (270).

When the touch gesture described above in the description of FIG. 5 is input from the outside, the controller 50 determines whether the corresponding touch gesture matches a predetermined touch gesture, and if the touch gesture matches the size of the X-ray irradiation area 45 and Display by adjusting the position. When the size and position of the X-ray irradiation area 45 in the second area 44 are changed by a touch gesture, the X-ray irradiation area 43 of the first area 41 is also superimposed on the image 42 of the object. The size and position will change. That is, the X-ray irradiation region 43 displayed in the first region 41 overlapping with the image 42 of the object is changed in association with the change of the X-ray irradiation region 45 displayed in the second region 44, through which the user The X-ray is irradiated to allow more precise and fine adjustment of the imaging area of the object 3 on which the image is taken. In the above, the control of the X-ray irradiation area 45 displayed on the second area 44 has been described as an example. Conversely, the X-ray irradiation area 43 displayed on the first area 43 may be adjusted or the first area It goes without saying that when the X-ray irradiation area 43 displayed on 43 is adjusted, the X-ray irradiation area 45 displayed on the second area 44 is interlocked therewith.

Since the touch gesture may be continuously performed until the desired X-ray irradiation area is formed, the controller 50 performs steps 260 to 270 until no touch gesture is detected in the X-ray irradiation area 45 of the second area 44. Repeat.

In step 260, if a predetermined touch gesture is no longer detected in the X-ray irradiation region 45 displayed on the second region 44, it is determined that the adjustment of the X-ray irradiation region 45 is completed, and the control process is completed.
