The present invention relates to a stereoscopic X-ray imaging apparatus, and more particularly, to acquire a left eye image and a right eye image of a subject at different positions using X-rays, and then display a three-dimensional image through a three-dimensional image display of a polarization method. A stereoscopic X-ray imaging device.

X-rays are short-wavelength electromagnetic waves generated by colliding electron beams that protrude from the cathode at high speed into heavy metals in vacuum discharge. They are not only highly transparent to the object but also have a fluorescent effect.

Therefore, invisible X-rays can be converted into visible light and photographed on a photographic film. Also, a part of the X-rays transmitted to the subject is absorbed and weakened by the subject, thereby changing the density or thickness of the subject. I can photograph it. X-ray inspection is a method of observing the inside of an object using these characteristics.

In addition, X-ray examinations can be classified into medical and industrial applications. Medical uses include chest X-rays, ultrasonography, computed tomography (CT) and magnetic resonance imaging (MRI). There are non-destructive inspections such as internal inspection of leaking devices and equipment and leak detection.

On the other hand, the three-dimensional image output device is largely divided into a glasses method and a glasses-free method, and the glasses-free method is a method of dividing the left and right images in the space according to the position of the observer's eyes in the lenticular and barrier method. It is a representative example.

This glasses-free method is convenient because it does not wear glasses, but when the observer moves from side to side and back and forth, the stereoscopic image is cut off and the resolution is inevitably caused by outputting synthesized left and right images using a single display. There are disadvantages.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing a stereoscopic X-ray imaging apparatus according to a first embodiment of the present invention.

Referring to FIG. 1, a stereoscopic X-ray imaging apparatus according to an exemplary embodiment of the present invention includes an X-ray light emitting unit 100, a sensor unit 200, a signal processing unit 300, and a stereoscopic image display unit 400. .

The X-ray light emitting unit 100 is provided with a light source (not shown) and a slit (not shown) for adjusting the width of the X-rays generated from the light source. In addition, the X-ray emission unit 100 irradiates X-rays to the object 10.

The sensor unit 200 receives the light passing through the object 10 and generates a constant image signal according to the amount of X-ray light passing through the object 10. In addition, the sensor unit 200 includes a charge-coupled device (CCD). However, the sensor unit 200 includes a complementary metal-oxide semiconductor (CMOS), a storage phosphor image plate, a photodiode, a photoconductor (a-Se, a-Si, etc.). ) Or TFT (Thin Film Transistor).

In addition, the sensor unit 200 generates a left eye image signal at a predetermined position a and transmits the left eye image signal to the signal processor 300, and moves a predetermined distance to generate a right eye image signal at a position b and transmits it to the signal processor 300. Therefore, the signal processor 300 may distinguish and recognize the left eye image signal and the right eye image signal. In addition, the sensor unit 200 moves in the x-axis (a-> b) direction, but may move in the y-axis direction and the z-axis direction. In the first embodiment of the present invention, the left eye image signal and the right eye image signal are generated while moving in the x-axis direction, that is, left and right.

The signal processor 300 includes a control device (not shown) and a graphic board (not shown) therein. In addition, the control apparatus (not shown) recognizes the image signals generated by the sensor unit 200 into a left eye image signal and a right eye image signal, and the graphic board (not shown) reads the image signals from a display device. It converts into left eye image data and right eye image data which can be included.

The stereoscopic image display unit 400 includes a first display device 410, a second display device 420, a half mirror 430, and an image inversion circuit 440.

The display devices 410 and 420 are formed of LCD panels 410 and 420 which are manufactured by attaching polarization filters 412 and 422 having the same polarization angle to 45 degrees on the front of the LCD liquid crystal panels 411 and 421. However, the LCD liquid crystal panels 411 and 421 may be formed of plasma display panel (PDP) panels or organic light emitting diodes (OLED) panels.

In general, since the polarizing filter is attached to the front panel of the LCD panel, there is no need to reattach the polarizing filter. However, since the polarizing plate is not attached to the PDP panel or the OLED panel, the polarizing plate should be attached to the front side.

In addition, the display devices 410 and 420 may be manufactured by attaching a polarization filter having a polarization angle of 135 degrees to the front of the display panels 411 and 421.

In addition, the first display device 410 and the second display device 420 may be manufactured by attaching a polarization filter having a front polarization angle of 90 degrees-0 degrees or 0 degrees-90 degrees, respectively.

As a result, when the left eye image and the right eye image are transmitted or reflected on the half mirror 430, the polarization angles of the left eye image and the right eye image formed on the half mirror 430 are 90 degrees. Suffice.

However, even though the polarization angles of the left eye image and the right eye image formed on the half mirror 430 are not necessarily 90 degrees, the left eye image and the right eye image having different polarization angles are formed on the half mirror 430 to separate the polarization angles. If the polarizing glasses 500 are visible, the viewer can observe the stereoscopic image.

The first display apparatus 410 receives left eye image data from the signal processor 300 and displays a left eye image.

The second display apparatus 420 receives the right eye image data from the signal processor 300 to display the right eye image, and the front lower end forms an edge with the front lower end of the first display apparatus 410 at a predetermined angle. . Preferably it is installed at 90 degrees. However, the predetermined angle may be changed according to the refractive index and the reflectance of the half mirror 430 provided between the display devices 410 and 420.

However, the right eye image may be displayed on the first display apparatus 410 and the left eye image may be displayed on the second display apparatus 420.

Therefore, the observer can observe the stereoscopic image by wearing only the left eye image in the left eye and the right eye image in the right eye by wearing polarization glasses 500 having different lens polarization angles from the left and right.

In the first embodiment of the present invention, the image of the first display apparatus 410 is transmitted and the image of the second display apparatus 420 is reflected. However, the image of the first display apparatus 410 may be reflected and the image of the second display apparatus 420 may be transmitted.

The half mirror 430 is a mirror that transmits light on one side and reflects light on the other side, and is also called a translucent mirror. In addition, the display apparatuses 410 and 420 may be maintained while maintaining a constant angle. Preferably, the display apparatuses 410 and 420 may be maintained while maintaining an angle of 45 degrees. However, the angle of 45 degrees may be changed according to the refractive index and the reflectance of the half mirror 430 and the left and right images displayed on the display devices 410 and 420 may be simultaneously formed on the half mirror 430 without being distorted. It is enough if you can.

The image reversing circuit 440 inverts the image of the display apparatus for illuminating the image on the reflective surface of the half mirror 430 of the display apparatuses 410 and 420 from side to side.

The reason is that since the reflection surface of the half mirror 430 is like a mirror, the image of the display device that is illuminated is inverted in left and right directions.

 In an embodiment of the present invention, since the right eye image of the second display apparatus 420 is reflected by the half mirror 430, the image inversion circuit 440 may right and left the right eye image of the second display apparatus 420. Invert

Accordingly, the left and right eye image signals generated by the sensor unit 200 are made into a stereoscopic image by the stereoscopic image display unit 400, and the observer wears polarized glasses 500 and forms a stereoscopic image formed on the half mirror 430. By looking at the observer can observe the X-ray image as a three-dimensional stereoscopic image.

2 is a view showing a stereoscopic X-ray imaging apparatus according to a second embodiment of the present invention.

Hereinafter, a description of the same components as in FIG. 1 will be omitted.

Referring to FIG. 2, a stereoscopic X-ray imaging apparatus according to another exemplary embodiment of the present invention includes an X-ray light emitting unit 100, a sensor unit 200, a signal processing unit 300, and a stereoscopic image display unit 600. The stereoscopic image display unit 600 includes a third display device 610, a fourth display device 620, and a half mirror 430.

In the stereoscopic X-ray imaging apparatus according to the second exemplary embodiment of the present invention, the stereoscopic image may be simply implemented without the image inversion circuit 440.

In general, the LCD panel 611 has a front polarizing filter 612 attached to the front of the LCD liquid crystal panel 611a and a rear polarizing filter 612a attached to the rear. In addition, when the LCD panel 611 is viewed from the front, the front-rear polarization angles of the front and rear surfaces are 45 degrees to 135 degrees and 135 degrees to 45 degrees by the front polarization filter 612 and the rear polarization filter 621a. Degrees, 0 degrees-90 degrees or 90 degrees-0 degrees make 90 degrees to each other. In addition, if the rear case and the backlight unit (BLU: Backlight unit) are removed due to the characteristics of the LCD, it is possible to see the transmission image in which the front and the left and right are reversed.

After the backlight 613 is separated from the third display apparatus 610 by using the structure of the LCD panel as shown in FIG. 2A, the LCD panel 611 is maintained 180 at the top and the bottom. After the rotation, the fourth display apparatus 620 in which the left and right directions of the image are reversed by combining the backlight 613 is manufactured. That is, the rear surface of the LCD panel 611 of the third display device 610 is the front surface of the LCD panel 621 of the fourth display device 620.

In addition, when the front-rear polarization angle is 45 degrees to 135 degrees and 135 degrees to 45 degrees, the front polarization angle of the third display apparatus 610 and the front polarization angle of the fourth display apparatus 620 are also the same. Since the half mirror 430 has a three-dimensional image having a polarization angle of 90 degrees to each other. However, when the front-rear polarization angle is 0 degrees to 90 degrees or 90 degrees to 0 degrees, the front polarization angle of the third display apparatus 610 and the front polarization angle of the fourth display apparatus 620 are 90 degrees to each other. However, the half mirror 430 forms a stereoscopic image having a polarization angle of 90 degrees.

Therefore, the image and the polarization of the third display apparatus 610 are transmitted to the half mirror 430, and the image and the polarization of the fourth display apparatus 620 are reflected and inverted. It can produce the same effect as 400).
