Description

Long-term diagnostic X-ray apparatus {Medical radiography system}

The present invention relates to a long-term diagnostic X-ray imaging apparatus, and more particularly to a long-term diagnostic X-ray imaging apparatus that can remotely photograph the organs, such as the stomach, duodenum, colon of the patient taking the contrast medium.

X-ray (X-ray) is a kind of electromagnetic waves, because of its high permeability to the material, it is widely used in non-destructive testing equipment, medical diagnostic equipment, medical treatment equipment. Medical X-ray imaging apparatus is a device for detecting abnormalities of bones, organs, ligaments, etc. in the body by irradiating X-rays to a specific part of the subject and imaging the transmitted light.

In general, an X-ray imaging apparatus installed in an X-ray imaging room of a hospital includes an X-ray generator, an X-ray detector, and a diagnostic table. The X-ray generator is a part that generates X-rays by accelerating electrons and is installed to be movable in order to irradiate X-rays to parts of the body. The X-ray detector is a device for sensing and imaging X-rays transmitted through the body, and is positioned to face the X-ray generator. The diagnosis table is a device that allows the patient to lie down so that the affected part can be photographed in a comfortable position.

Contrast may be used for long-term imaging using X-rays. The contrast agent is a substance with high sensitivity to X-rays, and when an examinee takes a contrast agent and performs X-ray imaging, an image of an organ such as the esophagus, the stomach, or the large intestine can be obtained more clearly. X-ray imaging with contrast agents can be used to vary the position of the subject, such as when the subject is lying or standing at a particular angle, or to photograph a particular organ with an external compression or inflation. The method can be used. Conventional X-ray imaging apparatuses used for X-ray imaging using such a contrast agent adopt a method of adjusting the angle of the diagnostic table by using a driving device installed under the large volume of the diagnostic table, thereby adjusting the height of the diagnostic table. Not only can not have the function, but if the weight of the equipment is large, the thickness of the floor is thin, it may be required to reinforce the load in the ceiling below. In addition, the subjects to be subjected to X-ray imaging are often inconvenient behavior. In this case, the patient is uncomfortable in the process of moving the patient lying on the separate movable bed to the diagnosis table of the X-ray imaging apparatus. I had to do it.

An X-ray imaging apparatus capable of compressing a specific organ during X-ray imaging uses a pressure bar. Conventional pressure rods press the organs of the subject by using a hemispherical pressing portion fixed at one end. When the pressing portion moves in contact with the body of the subject, the subject is subjected to friction between the fixed pressing portion and the skin surface. There is a problem that makes you feel an uncomfortable foreign object.

Therefore, the manufacturing cost can be reduced by a simpler configuration, and the diagnosis table is moved vertically, which makes it easy to transport the patient who is inconvenient to move, and by increasing the distance between the X-ray generator and the image detection detector, chest X-ray imaging is also possible. Therefore, there is a great need for the development of a long-term diagnostic X-ray imaging apparatus having a new configuration in which the subject may not feel foreign object during compression imaging.

Therefore, the problem to be solved by the present invention is that the imaging arm, the diagnostic table, the pressure rod is coupled to one fixed post can be taken in all positions for long-term shooting, while organs that can minimize the sense of foreign body during the compression of the organ It is to provide a diagnostic X-ray imaging apparatus.

According to one embodiment of the present invention, the pressure rod may be composed of a pressure support that is coupled to one end of the rotary bar to rotate in the direction of the diagnostic table and a rotating ball rotatably coupled to the other end of the pressure support.

The long-term diagnostic X-ray imaging apparatus of the present invention has the following effects.

1. The long-term diagnostic X-ray imaging apparatus of the present invention combines an X-ray generator, an X-ray detector, and a diagnostic table integrally with one fixed post to reduce the load of the X-ray imaging room with a configuration that is 50% or more simplified than conventional equipment. In addition, the construction period was shortened and the convenience and space utilization of X-ray imaging were improved.

2. The long-term diagnostic X-ray photographing apparatus of the present invention not only can adjust the angle of the diagnostic table, but also can move the diagnostic table up and down to enable chest X-ray imaging in this equipment, and the uncomfortable subject moves from the bed. It solved the inconvenience.

The long-term diagnostic X-ray imaging apparatus of the present invention can photograph various organs in a state in which a subject takes a contrast agent. When the subject takes the contrast agent, the contrast agent can move through the esophagus, stomach, and intestine, and increase the resolution of the captured image of each organ. In this case, in order to delay or speed up the movement of the contrast agent, it is necessary to change the position of the subject to be diagnosed. The long-term diagnostic X-ray imaging apparatus of the present invention can implement various imaging modes by remote control. Hereinafter, the configuration and operation of the long-term diagnostic X-ray imaging apparatus of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a long-term diagnostic X-ray imaging apparatus of the present invention. Referring to FIG. 1, the long-term diagnostic X-ray imaging apparatus 1000 is a post 100 fixed to a lower portion, a rotation bar 200 rotatably coupled to the front of the post, and a rotatable coupling to the front of the rotation bar 200. It consists of a diagnostic table 400 coupled to the movable arm 300 and the rotation bar 200 vertically. The X-ray generator 301 is coupled to the upper portion of the imaging arm 300 in the direction of the diagnosis table 400, and the X-ray detector 302 is coupled to the lower portion of the diagnostic table 400. The coupling relationship and operation of each component will be described in more detail with reference to FIGS. 2 to 7 below.

Figure 2 shows an example of the coupling relationship between the support frame and the rotation bar for fixing the diagnostic table and the operating means. Referring to FIG. 2A, a support frame moving hole 210 is formed at a side of the rotation bar 200 so that the diagnosis table support frame 410 may be coupled thereto, and at the diagnosis table support frame 410. The X-ray detector 302 is coupled. Although not shown in the figure, the diagnostic table is coupled to the upper portion of the diagnostic table support frame 410 such that the X-ray detector 302 is positioned below the diagnostic table. Referring to Figure 2 (b), the diagnostic table support frame 410 is fixed to the inside of the rotary bar 200, the diagnostic table support frame 410 is movable in the longitudinal direction of the rotary bar 200. . Movement of the diagnostic table support frame 410 may be implemented by various means. When the pinion gear 420 is rotated by the driving force of the driving motor 421 coupled to the diagnostic table support frame 410 as shown in the drawing, It may be implemented to move along the rack gear 422 meshed with the pinion gear 420. The X-ray detector may use a digital detector that realizes an image by a digital method.

Figure 3 schematically shows the coupling relationship between the rotation bar and the post and the operation of the rotation bar. Referring to FIG. 3, bearings 211a and 211b are provided in holes formed in the post 100, and the rotation shaft 220 of the rotation bar 200 is coupled to the bearings 211a and 211b. The upper chain gear 212 is formed on the rotary shaft 200, and when the lower chain gear 215 rotates, the rotary shaft 220 is coupled by the interconnected chain 213. The drive motor 214 may be used to drive the lower chain gear. When the rotation bar 200 rotates, the imaging arm 300 and the diagnosis table (not shown) connected to the rotation bar rotate together. X-ray imaging may be performed while changing the angle of the subject lying on the diagnosis table by the above method. have. It is preferable that the rotation angle of the rotation bar 200 can be changed to 90 degrees left and right. In a position where the post 100 and the rotation bar 200 are parallel to each other, the diagnostic table is horizontal, and in the position where the angle of the post 100 and the rotation bar 200 is 90 degrees, the diagnosis table stands vertically.

Figure 4 schematically shows the coupling relationship and operation of the imaging arm and the rotary bar. Referring to FIG. 4, the rotation bar 200 and the imaging arm 300 are connected by the imaging arm rotation connection part 310. When the driving motor 313 installed in the rotation bar 200 rotates the gear, the photographing arm rotation connection part 310 rotates to push the upper portion of the photographing arm 300 to one side. Although not shown in the drawing, the rotation bar 200 and the lower portion of the imaging arm 300 are connected to the shaft to induce rotation of the imaging arm 300. When the photographing arm 300 is rotated by being connected to the rotation bar 200 by the shaft, the guide roller 315 installed at one end of the photographing arm rotation connecting part 310 moves along the roller movement guide 317 so that the photographing arm ( 300 to help the smooth rotation. When the imaging arm rotates, the X-ray generating unit coupled to the upper portion of the imaging arm rotates together. At this time, the diagnosis table and the X-ray detecting unit are kept horizontal so that the organs of the subject can be photographed at an oblique angle.

5 illustrates an example of a structure for horizontally moving the diagnostic table. Referring to FIG. 5, the diagnosis table 400 may horizontally move in the longitudinal direction or the width direction. The horizontal movement of the diagnostic table can be implemented by various methods. The figure shows an example implemented by the driving rollers 430 formed on the upper and lower surfaces of the diagnostic table. The driving roller 430 may directly implement horizontal movement of the diagnostic table 400 as a roller having a driving function, but if necessary, it is possible to use a roller without driving force and add a separate driving device. Horizontal movement of the diagnostic table is necessary for imaging the organs of the subject at various positions. Since the X-ray generator and the diagnosis table support frame are fixed to the imaging arm, the diagnosis table may be horizontally moved with the diagnosis table support frame so that the imaging area may be changed. During X-ray imaging, the subject is held in a fixed state by holding the handle of the diagnosis table, and thus adjusting the horizontal position of the diagnosis table can capture a desired organ at a desired position.

When photographing organs using X-rays, it is necessary to temporarily photograph the organs of the subject. Long-term diagnostic X-ray imaging apparatus of the present invention has a special configuration for this.

6 is a view for explaining the structure in which the pressure bar is coupled to the imaging arm and the function of the rotating ball of the pressure bar. Referring to Figure 6 (a), the pressure rod is coupled to the shooting arm 300, the end of the pressing support 520 is coupled to the rotary ball 501, the other end is inside the shooting arm 300 It is connected to the rotation drive unit 522 is installed. Gears 521a and 521b are installed in the rotation driver 522 so that the pressure support 520 rotates downward while the gear rotates by the driving means. When the pressure support 520 is rotated downward and leveled (or the rotating ball may maintain an inclined angle tilted downward), the rotating ball 501 may press the organ of the subject while looking at the diagnostic table. It becomes an angle. The rotary drive unit 522 is coupled to the screw guide 511, the screw guide 511 is inserted into the screw bar 510 is coupled, when the screw bar 510 by the drive motor 512 rotates therein The screw guide 511 may move in the vertical direction along the formed thread line. By adjusting the vertical position of the screw guide 511 it is possible to adjust the strength that can press the organ of the subject. In addition, when the rotary ball 501 of the pressure rod is horizontally moved in the diagnosis table in a state in which the organ of the subject is pressed in a specific portion, the pressing area can be changed. In the long-term diagnostic X-ray imaging apparatus of the present invention, since the rotating ball 501 can freely rotate along the skin of the subject, the pain or foreign body feeling of the subject due to the change of the compression site can be minimized. The configuration for freely rotating the rotating ball 501 is shown schematically in Fig. 6 (b). Referring to the drawings, a portion of the rotary ball 501 may be installed in a form hidden inside the pressing support 520. That is, a circular hole is formed in the lower part of the pressing support so that a part of the rotating ball is exposed, and the plurality of rotating ball guide rollers 502a, 502b, and 502c are fixed to allow the rotating ball to be rotatable in the upper part of the rotating ball. May be installed in the pressure support 520. In the drawings is an example of a structure for rotatably fixing to the pressing support of the rotating ball, the specific structure may be variously modified as long as it maintains the function of the rotating ball. Although the drawing shows that the pressing support protrudes toward the front of the shooting arm, it forms a groove in the shooting arm so that the pressing support can be seated in the groove. It can also be configured not to protrude.

Hereinafter, the operation of the long-term diagnostic X-ray imaging apparatus of the present invention and various imaging modes will be described with reference to FIGS. 7 to 11.

Referring to FIG. 8, in the long-term diagnostic X-ray imaging apparatus of the present invention, the diagnostic table 400 may move freely in the horizontal direction. (A) of FIG. 8 shows an initial state, (b) shows the state which moved to the width direction, and (c) shows the state which moved to the longitudinal direction. This horizontal movement of the diagnostic table can be used to select a particular organ of the subject or the imaging position of the organ. Since the subject is lying on the diagnosis table and does not change its position, X-ray imaging of a desired part is performed by adjusting the horizontal position of the diagnosis table. Longitudinal horizontal movement of the diagnostic table may be especially required in the case of photographing the diagnostic table vertically. That is, in order to prevent the diagnostic table from touching the floor in the process of vertically turning the diagnostic table by rotating the rotary bar as shown in FIG. 9C, it is necessary to move the diagnostic table in the longitudinal direction in advance. This operation is preferably controlled automatically by a programmed method.

(A) of FIG. 9 shows an initial state, (b) and (d) show a state in which the diagnosis table 400 is inclined while maintaining the opposite angle, and (c) shows a diagnosis table 400. ) Shows a state of standing vertically. When X-ray imaging is performed in various modes, it is possible to obtain a clearer image of a desired organ by adjusting the moving speed of contrast medium.

10 illustrates a mode in which the terminal to be photographed can be photographed with the X-ray generator tilted. Referring to FIG. 10, when the photographing arm 300 rotates at a predetermined angle with respect to the rotation bar 200, the organ of the subject may be photographed at an oblique angle. (A) of FIG. 10 illustrates an initial state, and (b) and (c) illustrate modes of photographing by tilting the photographing arm at opposite angles. While the imaging arm 300 rotates, the X-ray detector maintains a parallel state with the diagnostic table.
