For example, when taking a chest X-ray, the practitioner moves the tube-shaped module 130 to move the first sensor 210 to a position corresponding to the second sensor 220 installed at the chest position of the dummy 120 The first sensor 210 and the second sensor 220 detect whether the tube shape module 130 has moved to a position corresponding to the photographing point of the dummy 120. [

If the second sensor 220 at the same position as the arm or the shoulder adjacent to the abdomen or the chest but not the chest position receives the transmission signal of the first sensor 210, it is determined that the positioning of the tube shape module 130 is wrong .

The third sensor 230 senses the position of the detector module 140 in the lower portion of the table 110 and the detector module 140 detects the position of the detector module 140 through the third sensor 230, Or the like.

In addition, the position determining unit 200 selects a point at which the center position C of the table 110 in the x-axis and y-axis directions coincides with the position of the tube shape module 130 as a reference position, The position of the table 110 and the tube shape module 130 are determined based on the position of the table 110 and the position of the tube shape module 130.

When the table 110 moves along the x-axis and y-axis directions on the reference position, the position determining unit 200 calculates the movement path of the center position C on the x, y coordinate system.

In the case of the tube shape module 130, the movement direction can be sensed with respect to the x-axis and the y-axis and the z-axis direction extending in the vertical direction, and the sensing information is also displayed in a coordinate system to grasp the position information.

The detector module 140 may detect the position of the tube shape module 130 and the detector module 140 through the third sensor 230. The detector module 140 may detect the position of the tube shape module 130 and the detector module 140, The center position C of the tube shape module 130 can be obtained relative to the center position C of the tube shape module 110 and the coordinates of the center position C of the tube shape module 130, It is determined whether the positions of the tube shape module 130 and the detector module 140 are in mutual positions.

Although not shown, the tubular module 130 may be formed to be capable of linear movement along the x, y, and z directions, as well as a connection portion between the tubular module 130 and the connection rod, The tube shape module 130 may be formed to rotate around the connection rod and the position determining unit 200 may be formed such that the proper position of the detector module 140 is calculated according to the rotation angle.

A stand 150 may be provided on one side of the table 110 and a lifting support 151 may be provided on the stand 150 so that the lifting support 151 can be vertically moved up and down. Can be mounted.

The table 110 is formed so that a subject to be photographed can be photographed to photograph an X-ray, and a photographing model can be provided in a stand 150 type in which the X-ray can be photographed in a standing state.

When the dummy 120 stands upright in front of the lifting support 151, the first sensor 210 of the tubular module 130 and the second sensor 220 of the dummy 120 are positioned It is determined whether the tube shape module 130 is located at an appropriate position.

The tube shape module 130 determines whether the photographing position is set at the proper position toward the elevation support 151 through the height of the elevation support portion 151 and the position of the coordinates of the tube shape module 130. [

The control unit 300 is an input means for the practitioner to input photographing conditions during the x-ray photographing exercise.

When shooting x-rays, the conditions of tube voltage (kV), tube current (mA), and irradiation time (sec) should be adjusted. Such photographing conditions may vary depending on the photographing point, the photographing purpose, and the person to be photographed. If you can not set these shooting conditions properly, you may get x-rays that are hard to read due to exposure or low exposure.

Therefore, the practitioner directly sets conditions for the tube voltage, the tube current, and the irradiation time through the control unit 300 to confirm whether the proper photographing condition is known, and pushes the switch 310 to proceed the photographing.

Although not shown, the x-ray imaging apparatus typically has a separate imaging room for the risk of exposure to radiation, and the control unit 300 may be provided outside the imaging room. In the present invention, The X-ray photographing unit 100 may be installed inside the photographing room and the control unit 300 may be located outside the photographing room to create an environment similar to the actual photographing environment.

The data storage unit 400 stores an image of an x-ray image according to the shooting condition and the shooting condition of each part.

The data storage unit 400 is divided into categories according to each photographing position, and image images photographed according to photographing conditions within each category can be stored. For example, an x-ray image category for the cervical vertebra is provided, and image categories for tube voltage, tube current, and irradiation time are stored in the category. These images may include both normally photographed images and abnormal images.

Also, an image taken at an accurate position and an image taken at a position other than an exact shooting position may be included.

The information processing unit 500 displays an x-ray image corresponding to the input information among the x-ray images stored in the data storage unit 400 on the display 510 through the input signals input from the position determination unit 200 and the control unit 300, Lt; / RTI >

For example, if the chest X-ray is taken, it is determined through the position determining unit 200 whether the tube shape module 130 is set at a position corresponding to the second sensor 220 mounted on the chest of the dummy 120 do. Then, it is determined whether the tube shape module 130 and the detector module 140 are located at mutually corresponding positions.

The information processing unit 500 also receives information on photographing conditions input from the control unit 300. When the position of the tube shape module 130 and the detector module 140 are in the normal position through the information inputted through the position determination unit 200 and the control unit 300 and the photographing condition is also set in the proper category, The processing unit 500 outputs a normal x-ray image of the corresponding region in the data storage unit 400 through the display 510.

However, when the positions of the tube shape module 130 and the detector module 140 are out of the predetermined position, or when the condition value set by the photographing condition deviates from the normal category, an erroneous x-ray image corresponding to the error factor is output.

Through this, the practitioner can find out the error factors and conduct the exercise again or feedback.

The procedure of practicing the X-ray imaging apparatus 10 according to the present invention will now be described with reference to the flowchart of FIG.

First, set the shooting conditions for the training. Proceed with the setting of the factors that affect the shooting conditions, such as the point to shoot and the age of the person to be photographed.

The practitioner sets the position of the table 110 on which the dummy 120 is placed and moves the position of the tube shape module 130 to a position corresponding to the photographing position. The detector module 140 is also located at a position corresponding to the photographing position.

After the position setting of the tube shape module 130 and the detector module 140 is completed, the practitioner goes out of the photographing room and sets photographing conditions, that is, the tube voltage, the tube current, and the irradiation time through the control unit 300. When the photographing signal is applied through the switch 310, the information processing unit 500 reads the information from the tube shape module 130 and the detector module 140 through the information input through the position determination unit 200 and the control unit 300, Is correctly set and whether or not the photographing condition is set correctly through the control unit 300. [

When the position and photographing conditions are set correctly, the information processing unit 500 outputs a normal X-ray image stored in the data storage unit 400. If the position setting of the tube shape module 130 or the detector module 140 is incorrect or the photographing condition setting is incorrect, an erroneous x-ray image corresponding to the error is outputted.

In addition, the information processing unit may display a part of the error part when an incorrect x-ray image is outputted due to an error in the position or photographing condition, so that the practitioner may perform feedback to correct the error.

The X-ray imaging apparatus 10 according to the present invention can reduce the exposure of the X-ray to the radiation exposure by omitting the actual irradiation of the X-ray, thereby enhancing the practical effects of the X-ray imaging apparatus.

The description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features presented herein.
