The image 42 of the object is displayed on the first area 41 of the plurality of areas. In addition, an image 42 of the object may be displayed to identify the object 3 in the fifth region 48 in which basic information of the object 3 such as personal information and disease history of the object 3 is displayed.

Here, each area of the user interface 40 will be described. The numbers assigned to each area are arbitrary, and thus will be described regardless of the order of the numbers.

In the third region 47, a list of photographing sites where X-ray imaging is performed is displayed. For example, assuming that the object 3 is a patient, a list of body parts such as the head, chest, belly, arms, and lower body is displayed, and selecting one of these lists gives a more detailed list of the photographed areas. Information about the photographing site may be displayed in the displayed format.

Information about the photographing site may be displayed in text or in the form of an icon symbolizing the features of each site. However, this is only an example, and other methods may be used as long as information on the photographing part is displayed. The user selects a shooting site by touching a desired shooting site from the list of shooting sites displayed as described above, or the remote controller 22, the mouse 23, the keyboard 24, the voice input device 25, and the motion recognition device. The photographing part may be selected through the input unit 21 including the 26. In the following description, the user's command is input through a touch as an example.

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

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 quadrangular shape. The X-ray irradiation area 43 may be set in advance so as to cover a predetermined area including the corresponding photographing part for each photographing part.

The contour of the X-ray irradiation area 43 may be circular or polygonal, but preferably has 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. A detailed description of the X-ray irradiation area control is overlapped with the description of the second area 44 to be described later, and will be replaced with the description of the second area.

When the photographing part is selected in the third area 47 and the X-ray irradiation area 43 overlaps with the image 42 of the object in the first area 41, the second area 44 does not display the object image. Only the X-ray irradiation area 45 is displayed separately.

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 also overlaps the image 42 of the object. The size and position will change.

That is, the X-ray irradiation area 43 overlapped with the image 42 of the object in the first area 41 changes in association with the change of the X-ray irradiation area 45 displayed in the second area 44, thereby allowing the user. The X-rays may be irradiated more precisely and finely control the photographing portion of the object (3) to be photographed.

Conversely, when adjusting the X-ray irradiation region 43 displayed in the first region 43, the X-ray irradiation region 45 displayed in the second region 44 may be adjusted in conjunction with this.

FIG. 5 is a diagram illustrating that the size, location, and shape of the 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 at which a touch is made, and a single circle with empty inside indicates an expected point at which a single circle filled with black is dragged and positioned. The dashed arrows indicate the path of movement and the double circle with one larger circle around the black filled circle indicates the point where the double touch is made.

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 of one side of the X-ray irradiation area 45. If you touch any point of one side of the X-ray irradiation area 45 and drag it toward the opposite side (a direction), the size of the X-ray irradiation area 45 can be reduced, and the opposite side of the opposite side (b direction) ), The size of the X-ray irradiation area 45 may be increased.

In addition, as illustrated in FIG. 5C, the user may adjust the size of the X-ray irradiation area 45 by touching and dragging respective points of two opposite sides of the X-ray irradiation area 45, respectively. By dragging each of the two opposite sides of the X-ray irradiation area 45 to the opposite side (c direction) while touching each other, the size of the X-ray irradiation area 45 can be reduced, and the opposite side of the opposite side Dragging in the (d direction) can enlarge the size of the X-ray irradiation area 45.

In addition, as illustrated 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. If you touch an arbitrary vertex of the X-ray irradiation area 45 and drag it to the opposite vertex direction (e direction) in the opposite direction, only the size thereof can be reduced while maintaining the original shape of the X-ray irradiation area 45, and the opposite diagonal When dragging in the direction (f direction), the size of the X-ray irradiation area 45 may be increased while maintaining the original shape. As described above, the touch gestures illustrated in FIGS. 5B, 5C, and 5D are merely 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 region 45 by dragging the X-ray irradiation region 45 in a direction to rotate the X-ray irradiation region 45 while continuously touching an arbitrary vertex of the X-ray irradiation region 45 twice. You can. At this time, the X-ray irradiation area 45 rotates on the spot 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 to rotate the X-ray irradiation area 45. The X-ray irradiation area 45 may be rotated by dragging. As in FIG. 5E, the X-ray irradiation region 45 rotates on the spot and does not move. As described above, the touch gestures illustrated in FIGS. 5E and 5F are merely examples of touch gestures for rotating the X-ray irradiation region 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 the user touches any three points within the X-ray irradiation area 45 simultaneously, the X-ray irradiation area 45 is initialized before its size, position, and shape are deformed.

In addition, as shown in FIG. 5H, when the user touches an arbitrary point inside the X-ray irradiation area 45 and drags it in an arbitrary direction and drags it again in the direction opposite to that direction, the X-ray irradiation area 45 has a size, It is initialized before the position and shape are modified. In the drawing, the X-ray irradiation region 45 is shown to be shaken from side to side, but this is only an example and is initialized by shaking the X-ray irradiation region 45 regardless of up, down, left, or right.

Returning to FIG. 4 again.

The fourth region 46 displays the size of the X-ray irradiation region and the amount of X-ray irradiation expected accordingly. The size of the X-ray irradiation area may be determined based on data about an area where photographing is mainly performed at each of the photographing regions of the object 3.

The X-ray irradiation amount according to the size of the X-ray irradiation region may be determined by calculating the X-ray dose varying according to the size of the X-ray irradiation region by using the X-ray dose irradiated during general X-ray imaging.

For example, when the chest is selected as the X-ray imaging region, the fourth area 46 displays a photographing area where the imaging is mainly performed at the chest region and the X-ray irradiation amount accordingly.

Also, the amount of X-ray radiation that changes as the X-ray irradiation region is adjusted is displayed in real time. Through this information, the user may roughly know how much X-rays are irradiated onto the object 3 according to the area of the X-ray irradiation area, and may adjust the size of the X-ray irradiation area with reference to this. For example, if 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 X-ray irradiation amount by reducing the X-ray irradiation area.

Information on the object 3 is displayed in the fifth region 48. When the object 3 is assumed to be a patient, information such as personal information and a disease record of the patient is displayed for the user to refer to for X-ray imaging. The arrangement of each region shown in FIG. 4 is merely an example and may have a different arrangement.

When the image 42 of the object is displayed on the display unit 30, the controller may further display an X-ray irradiation area for guiding adjustment of the X-ray irradiation area.

When the image 42 of the object is displayed on the user interface 40 of the display 30, the controller 50 overlaps the X-ray irradiation area 43 on 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 about a photographing region of the object 3 is input, the controller 50 irradiates X-rays to an area corresponding to the photographing region. The area 43 is overlapped and displayed. The X-ray irradiation area 43 may be set in advance so as to cover a predetermined area including the corresponding photographing part for each photographing part.

The controller 50 separately displays only the X-ray irradiation region 45 in the second region 44 of the user interface 40 of the display 30 (120). When the image 42 of the object and the X-ray irradiation area 43 overlap each other in the first area 41 of the user interface 40 of the display unit 30, the second area 44 of the image 42 of the object is displayed. Only the X-ray irradiation area 45 is separately displayed without a display.

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 controller 50 may 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 X-ray irradiation area 45 displayed in the second area 44 is changed in size and position 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 area 45 displayed in the second area 44, the controller 50 displays the X-ray irradiation area 45 deformed according to the touch gesture in the second area 44. (140).

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 also overlaps the image 42 of the object. The size and position will change. That is, the X-ray irradiation area 43 overlapped with the image 42 of the object in the first area 41 changes in association with the change of the X-ray irradiation area 45 displayed in the second area 44, thereby allowing the user. The X-rays may be irradiated more precisely and finely control the photographing portion of the object (3) to be photographed. In the above, the adjustment of the X-ray irradiation area 45 displayed on the second area 44 has been described as an example, but on the contrary, the X-ray irradiation area 43 displayed on the first area 43 may be adjusted or the first area may be adjusted. When the X-ray irradiation region 43 displayed on 43 is adjusted, the X-ray irradiation region 45 displayed on the second region 44 may be adjusted in conjunction with this.

When the X-ray irradiation area 45 displayed in the second area 44 is changed according to a predetermined touch gesture, the controller 50 determines that the X-ray irradiation area irradiated to the object 3 is deformed displayed in the second area 44. The X-ray irradiation area controller 10 is controlled to match the X-ray irradiation area 45 (150).

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

Since the touch gesture may be continued until the X-ray irradiation region desired by the user is formed, the controller 50 may perform steps 130 to 150 until the touch gesture is not detected in the X-ray irradiation region 45 of the second region 44. Repeat.

In operation 130, when the predetermined touch gesture is no longer detected in the X-ray irradiation area 45 displayed in the second area 44, it is determined that the adjustment of the X-ray irradiation area 45 is completed and the control process is completed.

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

Referring to FIG. 7, when photographing of the object 3 is performed 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 the 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 receiving the video signal of), in order to display the image 42 of the object on the display unit 30 outputs a signal for controlling the operation of the display unit 30 to the display unit 30. The display unit 30 displays the image 42 of the object in the first area 41 of the user interface 40 according to the signal transmitted from the controller 50.

The controller 50 displays a list of photographed regions 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 sites where X-ray imaging is performed is displayed. For example, assuming that the object 3 is a patient, a list of body parts such as the head, chest, belly, arms, and lower body is displayed, and selecting one of these lists gives a more detailed list of the photographed areas. Information about the photographing site may be displayed in the displayed format.

Information about the photographing site may be displayed in text or in the form of an icon symbolizing the features of each site. However, this is only an example, and other methods may be used if the information of the photographing part is displayed.

The controller 50 displays the X-ray irradiation area 43 overlapping 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 about a photographing region of the object 3 is input, the controller 50 irradiates X-rays to an area corresponding to the photographing region. The area 43 is overlapped and displayed. The X-ray irradiation area 43 may be set in advance so as to cover a predetermined area including the corresponding photographing part for each photographing part.

The controller 50 separately displays only the X-ray irradiation region 45 in the second region 44 of the user interface 40 of the display 30 (230). When the image 42 of the object and the X-ray irradiation area 43 overlap each other in the first area 41 of the user interface 40 of the display unit 30, the second area 44 of the image 42 of the object is displayed. Only the X-ray irradiation area 45 is separately displayed without a display.

The controller 50 displays the amount of X-ray radiation expected when X-ray irradiation is performed on the fourth region 46 of the user interface 40 of the display 30 (240).

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

The X-ray irradiation amount according to the size of the X-ray irradiation region may be determined by calculating the X-ray dose varying according to the size of the X-ray irradiation region by using the X-ray dose irradiated during general X-ray imaging.

Also, the amount of X-ray radiation that changes as the X-ray irradiation region is adjusted is displayed in real time. Through this information, the user may roughly know how much X-rays are irradiated onto the object 3 according to the area of the X-ray irradiation area, and may adjust the size of the X-ray irradiation area with reference to this. For example, if 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 X-ray irradiation amount by reducing the X-ray irradiation area.

The controller 50 displays information about the object 3 on the fifth area 48 of the user interface 40 of the display 30 in operation 250.

When the object 3 is assumed to be a patient, information such as personal information and a disease record of the patient is displayed for the user to refer to for X-ray imaging.

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 controller 50 may advance in the X-ray irradiation area 45 displayed on the second area 44. In operation 260, it is determined whether a predetermined touch gesture is detected.

The X-ray irradiation area 45 displayed in the second area 44 is changed in size and position 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 area 45 displayed in the second area 44, the controller 50 displays the X-ray irradiation area 45 deformed according to the touch gesture in the second area 44. 270.

When the touch gesture described above in the description of FIG. 5 is input from the outside, the controller 50 determines whether the touch gesture corresponds to a predetermined touch gesture, and when the touch gesture is matched, the size of the X-ray irradiation area 45 according to the touch gesture and Adjust the position to display. 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 also overlaps the image 42 of the object. The size and position will change. That is, the X-ray irradiation area 43 overlapped with the image 42 of the object in the first area 41 changes in association with the change of the X-ray irradiation area 45 displayed in the second area 44, thereby allowing the user. The X-rays may be irradiated more precisely and finely control the photographing portion of the object (3) to be photographed. In the above, the adjustment of the X-ray irradiation area 45 displayed on the second area 44 has been described as an example, but on the contrary, the X-ray irradiation area 43 displayed on the first area 43 may be adjusted or the first area may be adjusted. When the X-ray irradiation region 43 displayed on 43 is adjusted, the X-ray irradiation region 45 displayed on the second region 44 may be adjusted in conjunction with this.

Since the touch gesture can be made continuously until the desired X-ray irradiation area is formed, the controller 50 performs steps 260 to 270 until a touch gesture is not detected in the X-ray irradiation area 45 of the second area 44. Repeat.

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