Description

TUBE SUPPORTER OF 3D DIGITAL RADIOGRAPHY SYSTEM, MAIN DRIVE UNIT OF 3D DIGITAL RADIOGRAPHY SYSTEM AND PHOTOGRAPHING POSITION ADJUSTMENT METHOD USING THEREOF}

The present invention relates to a tube support, a main drive unit and a photographing position adjusting method of a medical 3D digital radiography system capable of radiography of various positions, and 3D implementation by combining partial X-ray information with each other.

In general, a medical diagnostic radiography apparatus refers to a method of irradiating X-rays to a human body and detecting a difference in energy intensity distribution of the transmitted radiation. There are analog and digital methods as detection means.

The analog method is a method of obtaining a visible image by combining a silver sensitizer (fluorescent plate) that emits light when receiving radiation with a silver salt film to form a latent image on the silver salt film with light generated by the sensitizer, and then chemically treating the silver salt film. . There is a film cassette which stores the sensitizer and the film in a dark state in order to obtain the above method and uses it for photographing.

Digital Radiography (DR) uses radiographic image detectors to record and digitize absorption and location information as an electrical signal. Say how to display.

Existing digital radiography system can be divided into generator which generates X-ray through tube and receiver which receives X-ray through detector, and it can be classified according to the shooting position (posture) of patients who take X-ray in hospital. The operation method can be divided into two types, a stand method for photographing the chest (chest) and a table method for photographing lying on the patient's table.

The distance between the X-ray generating part and the receiving part of most shooting positions is about 100cm, but some of the stand-type shooting positions such as chest shooting are taken farther than the normal shooting distance (over 100cm) due to the prevention of enlarged heart shadow. It is universal to do.

In order to extinguish all of these special imaging positions, the distance shift of the X-ray generator or receiver on the system (ie, the focal-to-surface distance: SID) must be possible.

Thus, a technique related to a radiographic apparatus has been proposed in US Patent Publication No. 20100284601 and US Patent No. 6200024.

Hereinafter, the structure of the radiographic apparatus disclosed in US Patent Publication No. 20100284601 and US Patent No. 6200024 as a prior art will be briefly described.

1 is a schematic diagram of a C-type arm radiation transmission imaging system of US Patent Publication No. 20100284601 (hereinafter referred to as 'Prior Art 1'). As shown in FIG. 1, the prior art 1 does not require structural changes, and can generate three-dimensional CT-type information using existing features of the C-arm. The C-arm 10 is a two-dimensional absorption generated by passing X-rays through an X-ray source 12 at one end and a patient 16 lying on the bed 17 at the other end. A detector array 14 for detecting an image is provided. The detector array preferably includes an image intensifier coupled to the video camera to convert incident photons into an image signal that dynamically represents X-ray absorbing shadow images.

However, the C-type arm radiographic imaging system according to the prior art 1 has a problem in that the position where the X-ray source 12 rotates together with the detector array 14 can be photographed.

2 is a perspective view schematically showing a C-arm system of US Patent No. 6200024 (hereinafter referred to as 'Prior Art 2'). As shown in Fig. 2, the prior art 2 is supported by a curved support carriage A, in which the C-type arm C is adjacent to the inspection area E and curved. The inspection area E may be changed along the X, Y and Z axes. The X-ray transmissive bed 10 moves so that the imaging area of the patient lying on the bed can be located within the examination area E. FIG.

Rotation support assembly (A) contains a rotation mount or bearing 14 to which a fixture for rotation about a horizontal axis X is installed. The rotary mount 14 is fixed to a track or other mechanism 18 to enable the movement of the mount in the Y and Z axial directions as well.

The midpoint 22 of the C-shaped arm C is provided in a rotatable form with respect to the bearing 14. The C-type arm C constitutes two opposing parallel ends 24 and 26 on either side of the inspection region E. As shown in FIG. The C-type arm C drives the detector 28 and the X-ray source 30 by repeatable driving.

However, the C-arm system according to the related art 2 has a problem in that the detector 28 rotates with the X-ray source 30 and thus there is a limit in the position that can be taken.

In addition, in the conventional digital radiography systems, when the axes of the X-ray generator and the receiver are divided, one or two axes move to the left or right to adjust the distance, or the generator and the receiver are respectively one axis. It is configured in the form of an arm so as to be movable left and right (or up and down).

However, when each axis or arm is moved in such a left-right movement manner, there is a problem in that photography is limited because the center of the tube is misaligned at some positions where the shooting angle is changed by changing the angle of the detector.

In addition, as shown in FIG. 3, the equipment having one detector of the existing digital radiography system has a problem in that a storage space is enlarged according to a moving distance because the tube or the detector is moved left and right in order to change the SID. .

According to these drawings, the tube support 500 of the medical 3D digital radiography system according to the present embodiment is fixed to the upper end of the frame 300 of the tube 400 of the medical 3D digital radiography system 100 by the tube SID (conductor focal-water plane distance), multi-sided imaging and angle imaging of 400 are enabled.

Tube 400 is a component for generating and irradiating radiation for radiography, it may have a radiation source for generating radiation therein.

The radiation irradiated from the tube 400 passes through the body of a subject, a subject, or a patient to display an image of a pattern specific to the detector 600. The detector 600 may convert an image represented by radiography into a digital image and transmit the converted image to a digital image processing apparatus for post-processing.

Here, the tube support 500 will be described while describing components of the 3D digital radiography system.

The medical 3D digital radiography system 100 includes a main driver 200, a tube 400, a tube support 500, a detector 600, a detector driving module, and a controller.

In particular, the medical 3D digital radiography system 100 to which the tube support 500 of the medical 3D digital radiography system of the present embodiment is applied is an up-down of the frame 300 and a rotation of the frame 300. Rotating, sliding of the frame 300, rotating of the detector 600, up-down of the detector 600, SID of the tube 400 (distance between the focal-water plane of the X-ray tube) ) Rotation, rotation of the tube 400 and tilting of the detector 600 may be performed.

The main driver 200 includes a stand 210, a frame 300, and a frame driving module.

The stand 210 is provided in an upright state, and the frame 300 is installed at the front, and a frame driving module for driving the frame 300 is installed therein.

The frame driving module includes an up-down driving module 310, a rotating driving module 320, and a sliding driving module 330.

The up-down driving module 310 is installed inside the stand 210 to up-down the frame 300 by a set height, and may be implemented by a cylinder or a motor, a rack, and a pinion. In this case, the up-down driving module 310 may up-rotate the rotating driving module 320.

The rotating driving module 320 is installed inside the stand 210 to rotate the frame 300 by a set angle (rotating), it may be implemented as a motor.

The sliding drive module 330 is installed in the up-down drive module 310 and the guide 322 through which power is transmitted by driving the rotating drive module 320 to rotate the frame 300 downward by a predetermined angle or The frame 300 rotates upward and slides the frame 300 in a state of rolling contact with the rear surface of the frame 300 by a roller rotated by the driving of a motor, or a pinion rotated by a motor is the frame 300. The frame 300 may be engulfed by a rack formed along the outer circumferential surface of the slid.

The tube 400 is installed in front of the upper end of the frame 300 through the tube support 500.

The tube support 500 allows the distance between the tube 400 and the frame 300 to be adjusted through a joint driving method, so that the SID (conductor focal-water surface distance), multi-sided photographing and angle photographing of the tube 400 can be performed. And a first joint 510a, a second joint 510b, shafts 512a and 512b, and shaft drivers 514a and 514b.

The first joint 510a is connected to the upper end of the frame 300 of the main drive unit 200 with the lower rear end thereof rotatable and the second joint 510b is disposed in front of the first joint 510a.

The shafts 512a and 512b are connected to the upper surfaces of the opposite surfaces of the first and second joints 510a and 510b and the opposite surfaces of the tube 400 opposite to the lower ends of the second joints 510b.

The shaft driving units 514a and 514b are motors that provide rotational force to the shafts 512a and 512b according to a control signal of the controller. The shaft driving units 514a and 514b provide rotational force to the first joint 510a and the tube 400 and rotate by the rotational drive. When the first and second joints 510a and 510b are fully unfolded, a moving distance corresponding to a maximum of twice the folded length may be secured. That is, the multi-axis, in particular, the rotation between the two axes (512a, 512b) when the maximum distance between the focal plane and the water plane is 80cm, for example, even if only 40cm to move the distance between the focal plane and the water plane can be secured. This can reduce the space required for the storage of the entire system, reducing the charge space, and easy to store and manage the tube (400).

In this way, the front upper end of the frame 300 is connected to the lower rear of the first joint 510a of the tube support 500, and the shaft 512a and the shaft drive unit 514a in front of the first joint 510a. The second joint 510b is connected through the tube 400 through the shaft 512a and the shaft driver 514a at the front lower end of the second joint 510b, so that the SID ( In addition to adjusting the focus-to-water surface distance, multiple area shooting and angle shooting are possible.

Since the angle of the tube 400 can be freely adjusted by driving the tube support 500, various angles can be taken while the detector 600 is fixed, and the photographing area can be reached to a tomo position through automatic driving. There is an advantage to widen.

The detector 600 includes a detector body 610, a detector up-down module 620, a detector arm 630, and a detector rotation driving module 640.

The detector up-down module 620 raises and lowers the detector main body 610 by a set height through control of a controller, and a cylinder or the like is applied thereto.

The detector arm 630 is installed at the lower end of the frame 300 and is rotated by a set angle by the detector rotation driving module 640. Here too, the detector rotation driving module 640 is controlled to be driven by the control unit.

In particular, like the tube support 500, the frame 300 and the detector arm 630 supporting the detector 600 also constitute a double arm structure, and through the double structure of both arms, the existing one detector system (one The detector system has the advantage that it is possible to shoot some positions that are difficult to shoot. In this case, the reason why the double structure is required for both the tube 400 and the detector 600 is that the center between the tube 400 and the detector 600 when only one of the tubes 400 and the detector 600 changes the angle. This is wrong. In addition, the height of the detector 600 may be adjusted to enable flexible movement and position of the frame 300 in a table mode (see FIGS. 10 to 13).

Referring to FIG. 10, it can be seen that the tube 400 and the detector 600 rotate according to the rotational movement of the frame 300 forming the body of the C-arm, and thus the photographing direction may be changed differently. have. In this case, in the apparatus of the present invention, the frame 300 and the frame 300 are rotated in accordance with the rotation of the detector arm 630 located in the lower portion of the frame 300 (the lower portion in FIG. 10 and the inner side of the frame 300 in FIG. 5). Even if the tube 400 takes various directions, the detector 600 may be controlled so that the detector body 610 may maintain the horizontal direction. This is possible because the detector arm 630 forms a double arm structure with the frame 300.

That is, when the frame 300 and the tube 400 rotate by the rotation of the rotating driving module 320, which is not shown in detail in FIG. 10, the rotation driving module 640 may be rotated with the rotation of the rotating driving module 320. By rotating in reverse, the detector body 610 can maintain its position and orientation.

In FIG. 11, another exaggerated example in which various imaging angles between the tube 400 and the detector 600 may be adjusted by the operation of the double arm of the detector 600 is illustrated. That is, the entire frame 300 is rotated about the axis by the rotating driving module 320, the detector 600 is the magnetic seat despite the rotational movement of the frame 300 by the operation of the detector arm 630 (Upright) can be kept as it is. According to such an embodiment, an image from various angles may be obtained, and through this, when the tube 400 is photographed for each part of the trajectory by the rotation of the frame 300 and then combined with each other, a tomo image or It is also possible to generate 3D images. In FIG. 11, the rotational movement of the detector arm 630 is exaggerated without the rotational movement of the frame 300.

10 and 11 are different but the same in that they describe one aspect of the present invention. In addition, the embodiment of the apparatus shown in Figures 10 and 11 is somewhat different in the ratio of the length and height, which is intended to show that the spirit of the present invention is not limited by a specific length and height, various embodiments It can be implemented through.

Meanwhile, in FIGS. 10 to 13 and the frame 300 supporting the tube 400 and the detector 600 on the front and the bottom, respectively, has a “C-arc” shape. As a result, since the frame 300 in which the tube 400 and the detector 600 are installed is a C-arc type arm, when the table mode is applied, the orbital driving may be possible without changing the center of the table. will be.

As a result, the frame 300 can be moved up / down through up-down driving. The advantage of this movement is that the patient can be photographed on the frontal (AP) or side (Lateral or Oblique) of the patient even if he is lying on the table without movement. This drive can be said to be an advantageous mechanical characteristic when photographing an emergency patient or a patient with poor mobility. In particular, unlike the existing system when the image of the trajectory position is taken, the interference between the table, the detector 600 and the detector arm 630 does not occur.

Referring back to FIG. 10 or 11, the rotation of the detector 600 is made about the central axis of the detector rotation driving module 640 installed in the detector arm 630, and the rotation of the frame 300 is the rotating driving module. It is made about the axis of 320. At this time, "C-arc" of the frame 300 may be made to slide along the axis of the rotator driving module 320 with the center axis of the detector rotation driving module 640 of the detector arm 630. However, the axis of the detector rotation drive module 640 of the detector arm 630 and the axis of the rotating drive module 320 do not necessarily have to coincide with each other, and as shown in FIG. 12, the detector rotation drive module of the detector arm 630 is shown. Various photographing positions are possible regardless of whether the central axis and the axis of the rotating driving module 320 coincide with each other.

Therefore, as shown in FIG. 12, the TM joint (Temporomandibular Joint, Temporomandibular joint), Skyline view (Landscape), L through the method of adjusting the shooting position using the tube support and the main drive of the medical 3D digital radiography system of the present invention as shown in FIG. -Spine obligue, lumbar spine, pelvis outlet, calcaneus, and both shoulder can be taken.

The imaging position adjusting method using the tube support and the main driver of the medical 3D digital radiography system of the present invention has the following position advantages.

First, high angle shooting of 30 degrees or more is possible. Here, 30 degrees or more means a spaced angle deviating therefrom when the angle between the conventional tube and the detector is 0 degrees. For example, in the photographing system of the present invention, Pelvis outlet photographing, Calcaneus photographing, Skyline view, T-M joint photographing, and the like are possible. That is, since the detector 600 and the tube 400 have a double arm structure, even if the angle of the tube 400 is changed, the detector 600 can be corrected by the center of the twist by the driving of the detector rotation driving module 640. will be. These shooting positions were variously used for recording shooting by manually setting the radiographic apparatus before the automated shooting system appeared. However, as the radiographic system is gradually automated, the movement of tubes and detectors is mainly used. Because they were limited to their movements, they tended to narrow the shooting position that the user could choose. The present invention solves these problems and is an automated photographing system, that is, an automatic system in which a user automatically manipulates a variety of movements such as a remote control without manually setting the position and angle of the device. It is designed to be equipped and differentiated from the existing digital radiography system in that it enables users to implement various shooting positions to meet the desired purpose.

Second, when shooting both shoulders, it is possible to shoot a large area up to 24 "in the case of a 17" x 17 "detector by utilizing the active area of the detector 600 to a diagonal length.

When shooting both shoulders, the frame 300 of the main driving unit 200 is set through the rotating driving module 320 to enable the SID (distance between the tube focus and the water surface), the multi-face shooting, and the angle shooting of the tube 400. After rotating at an angle, the tube 400 is spaced apart from the detector 600 through the shaft drives 512a and 512b of the tube support 500, the moving distance of the tube 400, and the tube 400 of the tube 400. At least one of the rotation angles is adjusted. Next, X-ray information obtained after transmitting the X-ray generated in the tube 400 through the body is collected through the detector.

Third, when taking L-spine obligue, lumbar spine can be taken while the patient is lying down. It is possible to rotate by the sliding of the frame 300, so that even patients with uncomfortable behavior, such as emergency patients can be taken in the lying down state without any change in posture when taking lumbar series.

When the L-spine obligue is photographed, the frame 300 of the main drive unit 200 rotates downward at a set angle through the sliding drive module 330 so that orbital photographing of the tube 400 is possible. The X-ray information generated at 400 and transmitted through the body for each angle may be collected through the detector 600, and then the controller may reconstruct the image taken for each angle, and then output the 3D through the display.

Fourth, when X-ray tomography (tomography), it is possible to shoot a variety of angles of the tube 400 without moving the center of the detector 600, it is possible to shoot a tomo (tomo) that requires a variety of angles in one position.

During the tomography, the frame 300 of the main driving unit 200 is sequentially rotated downward by a predetermined angle through the sliding driving module 330, and then the tube 400 Collects x-ray information transmitted through the body at each angle through the detector 600, reconstructs the image photographed by the controller at the angle, and outputs the reconstructed image through the display.

FIG. 14 is a perspective view illustrating a state in which a table is applied in a stand mode in a medical 3D digital radiography system to which a tube support of the medical 3D digital radiography system according to the present invention is applied, and FIG. 15 is a medical 3D digital radiation according to the present invention. In a medical 3D digital radiography system to which the tube support of the imaging system is applied, a table is applied in a table mode in a perspective view, and FIGS. 16 and 17 are applied to the medical tube support of the medical 3D digital radiography system according to the present invention. In the 3D digital radiography system, the state before and after the change of the table angle is shown in plan view.

According to these drawings, the 3D digital radiography system 100 may be further provided with a table 700, and the table 700 may include a table module and a table driving module including a top plate 710 and a support 720. 800). At this time, the support 720 is provided with a wheel to facilitate movement at the bottom.

In particular, since the table 700 may be applied to the 3D digital radiography system 100, an up-down of the frame 300, rotation of the frame 300, and the frame 300 are performed. Sliding), rotating the detector 600, up-down of the detector 600, rotating the SID (focal-level surface) of the tube 400, rotating the tube 400 In addition to the tilting of the detector 600, rotation of the table 700, sliding of the table 700, and the like may be performed.

In particular, since the table 700 changes the stand mode and the table mode through the table module on the basis of the fixed axis, the table 700 and the detector 600 separately after the shooting position is changed. And the table 700 and the detector 600 may always be located in the same position without having to center the tube 400. Through this, radiologists (users) have a lot of power to move the table and have high fatigue due to frequent changes, which has the advantage of eliminating this part.

In addition, the left and right movement of the table 700 is driven by the power based on the table guide. The advantage of this feature is that the whole body can be taken automatically while the patient is lying down in table mode. This is because the movement of the table 700 is made automatically, it is possible to shoot the entire body (or spine, etc.) without errors due to shaking during movement. As a result, it is possible to minimize the superposition of the image has the advantage of reducing the exposure of the patient.

The table driving module 800 drives the table module to be orthogonal to the digital radiography system 100 to allow the patient to stand in the stand mode in which the patient stands up between the tube 400 and the detector 600, or the digital radiation It is driven to be parallel to the imaging system 100 to wait in the table mode in which the table module is located between the tube 400 and the detector 600.

As a result, as shown in FIG. 15, the present invention enables manual / electric rotation through the operation of the table driving module 800 when the table mode is changed to the table position in the stand mode state. Movement control is possible. (Generally, it is called 4-way table because it is possible to move in four directions.) In the table mode, forward / backward movement can be done manually / electrically, and in case of electric control, braking by motor is achieved. In case of manual control, it is possible to brake by electromagnet.

In addition, in the present invention, when the mode is changed through the table 700, the control of the table 700 is made manually, and a separate control button is placed next to the handle 712 to perform manual movement control.

In addition to the operator console (operator console) mounted on the collimator by adding the operator console (O, P) of the same system structure to the table 800, in the stand mode, the user can operate directly next to the patient. In particular, the operator console mounted on the table 700 is a structure that can be freely positioned and mounted in the table 700 in a configuration that enhances the user's convenience of operation.

And the table module is provided with a handle 712 to be driven to the outer end of the top plate 710, the table movement control buttons are provided on both sides of the operator console (O, P) side, the switch on the front side of the table safety device ( S) is provided, and a sensor (not shown in the drawing) is provided on the handle 712 to detect an object, so that the lock / unlock of the handle 712 is possible. Left and right movement control is possible through 712.

In addition, the table 700 is not only moving the top plate 710 when the table 700 is moved, but a structure in which the entire table moves (a guide is located at the bottom of the table), thereby increasing the space efficiency of the top plate 710.

The difference between the table 700 and other emergency room tables or room tables is that the table module does not provide a cushion function as a mattress. (The most important factor in selecting the top plate 710 of the X-ray table is to scatter X-rays. , Transmission, etc.)

In case of people with discomfort, such as emergency room emergency patients, the patient table must feel uncomfortable when moving the X-ray table and receive all the shocks during the movement.

Then, by using the space of the top plate side portion of the table module to form a roller-like handle 712 is good. At this time, the outer portion of the handle 712 is made of a material that can absorb the shock when moving the patient. Furthermore, the rotation of the handle 712 can be electrically assisted to assist the patient's table movement, and the rolling of the handle 712 can be applied to the fan belt method instead of the roller method, and the handle 712. It can be applied to adjust the height of the patient table so that it can be adjusted.

As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above embodiments, and those skilled in the art to which the present invention pertains various modifications and variations from such descriptions. This is possible.

Therefore, the scope of the present invention should not be limited by the described embodiments, but should be determined by the equivalents of the appended claims, as well as the appended claims.
