Abstract

Provided is a structure which enables a flat plate detector such as an FPD to be easily housed in a mobile X-ray device and easily taken out thereof, and does not easily make an impact. The present invention has a configuration in which a box (80) for housing a flat plate detector (5) is disposed on a side surface of a main body (2) of a mobile X-ray device, and the upper surface of a bottom plate of the box (80) is inclined with respect to the ground contact surface of a truck (1) in the front-back direction of the main body (2). Consequently, the inclined upper surface of the bottom plate and the upper end of one side plate (83) are brought into contact with the flat plate detector (5) to thereby support the flat plate detector (5) in an inclined position. When the flat plate detector (5) is taken out of the box (80), the flat plate detector (5) can be taken out while being rotated within a principal plane with the upper end of the side plate (83) that is in contact with the flat plate detector (5) as a fulcrum. Therefore, the flat plate detector (5) can be easily taken out of the box (80) without the need for vertically lifting the flat plate detector and pulling the flat plate detector out of the box (80).

Description

Mobile X-ray apparatus and plate-type detector extraction method

The present invention relates to an X-ray apparatus that moves in a facility such as a hospital and performs X-ray imaging.

The mobile X-ray device can move in a facility such as a hospital by operating the operator. Therefore, the subject on the bed can be radiographed by being placed in a place other than the X-ray imaging room, for example, on the bedside of the subject's hospital room. As described in

Patent Documents

1 and 2, the mobile X-ray apparatus has a configuration in which a main body with a built-in battery and an X-ray generation unit are mounted on a carriage. The X-ray generation unit is supported by a support column that is rotatably supported on the carriage. As a means for converting X-rays transmitted through the subject into an image, in addition to an X-ray film cassette, in recent years, an IP (Imaging Plate) cassette using a stimulable phosphor as an X-ray conversion layer, or an X-ray conversion layer A flat plate X-ray detector such as an FPD (Flat Panel Detector) using a semiconductor is used. These are inserted between the subject and the bed at the time of imaging.

In the case of a mobile X-ray apparatus using an IP cassette, an image reading device is built in the main body of the mobile X-ray apparatus as disclosed in Patent Document 2. After the imaging, when the IP cassette is inserted into the image reading apparatus, the IP cassette is irradiated with laser light, and the stored image information of the subject is read out.

On the other hand, since the FPD can directly output an image signal as described in Patent Document 2, an X-ray image can be displayed in a few seconds on an image display unit arranged in the main body of the mobile X-ray apparatus. . As a method of transferring an image signal from the FPD to the main body, there are a method of connecting the FPD and the main body with a detachable cable as in Patent Document 2, and a method of transmitting the image signal from the FPD to the main body by wireless communication.

Further, Patent Document 1 discloses a configuration in which a case (pocket) is attached to the side surface of the main body of the mobile X-ray apparatus, and the FPD is accommodated in the case when moving. With this configuration, the FPD hardly protrudes in the width direction of the mobile X-ray apparatus, the FPD does not become an obstacle when the mobile X-ray apparatus is run, and the FPD can be easily taken in and out at the time of imaging. it can. Patent Document 2 also discloses a configuration in which an FPD is set up in a space between a support on a carriage and a main body.

JP 2007-535 A JP 2011-250931 A

The FPD is heavy because a semiconductor layer as an X-ray conversion layer, a pixel electrode, a TFT (thin film transistor) substrate, and the like are disposed therein. In addition, some have a large area (for example, 46 cm on a side) so that a wide portion of the subject can be imaged at one time. In order to prevent damage to the built-in semiconductor layer and circuit, it is desirable not to give an impact to the FPD. After moving the mobile X-ray device close to the limited space on the bedside and stopping it, take out a large area and heavy FPD from the pocket on the side of the main body, change the direction, and insert it between the subject and the bed The work to do may be burdensome for the operator. For example, when an FPD is inserted into a case (pocket) as shown in FIG. 5 of Patent Document 1, it is necessary to lift the vertically inserted FPD vertically and take it out of the pocket. The pocket of FIG. 5 of Patent Document 1 has a side height shallower than the front height (paragraph 0051). Therefore, if it is difficult to lift the FPD to the upper end of the front of the pocket, The FPD can be lifted vertically up to a height and horizontally moved parallel to the main plane while maintaining the height. However, it is not easy to lift a heavy FPD vertically to a certain height (the height of the side of the pocket) and move it horizontally until all large FPDs escape from the pocket while maintaining it. It seems that the burden is particularly great for a short operator or an operator who does not have enough strength. The same operation is required when the FPD is accommodated in the pocket after the photographing is finished. The same problem arises not only with FPD but also with IP.

An object of the present invention is to provide a structure in which a flat panel detector such as an FPD can be easily accommodated in a mobile X-ray apparatus, can be easily taken out, and is not easily shocked.

In order to achieve the above object, in the present invention, a box for accommodating a flat panel detector is disposed on the side surface of the main body of the mobile X-ray apparatus, and the upper surface of the bottom plate of the box is the main body with respect to the grounding surface of the carriage. It is set as the structure inclined in the front-back direction. As a result, the inclined upper surface of the bottom plate and the upper end of one side plate are brought into contact with the flat plate detector, and the flat plate detector is inclined and supported.

In the present invention, since a flat panel detector such as an FPD is inclined and accommodated in a box on the side of the main body, when the flat panel detector is taken out from the box, the upper end of the side panel in contact with the flat panel detector With the fulcrum as a fulcrum, the flat plate detector can be taken out while rotating in the main plane. Therefore, it is not necessary to lift the flat detector vertically and pull it out of the box, and it can be easily taken out from the box.

A mobile X-ray apparatus according to the present invention includes an X-ray generator, a column supporting the X-ray generator, a main body having a function of controlling the X-ray generator, and a carriage on which the main body and the column are mounted. Have. A box for receiving a flat panel detector for detecting X-rays is provided on a side surface of the main body. The box includes a front plate parallel to the side surface of the main body, a bottom plate, and side plates provided on the left and right of the front plate. At least a part of the upper surface of the bottom plate is inclined in the front-rear direction of the main body with respect to the grounding surface of the carriage, and the inclined upper surface of the bottom plate and the upper end of one side plate are in contact with the flat panel detector The flat plate detector is tilted and supported.

This allows the flat detector to be taken out of the box while rotating in the main plane. It is desirable that the distance between the left and right side plates is designed to be a size that can be removed from the box while rotating as described above.

In addition, there is a space between the upper end of the other side plate and the flat plate detector in a state where the inclined upper surface of the bottom plate and the upper end of one side plate are supported in contact with the flat plate detector. It is desirable. If this space exists, even if a force in the direction opposite to the inclination is applied to the upper part of the inclined flat plate detector in the front-rear direction of the main body, the flat plate detector uses the space to make a flat plate type. Since the detector can rotate in the direction opposite to the tilt, it can absorb the impact. Specifically, with the inclined upper surface of the bottom plate and the upper end of one side plate in contact with and supported by the flat detector, the lower end of the side of the flat detector on the side of the other side plate is a fulcrum. As described above, the flat panel detector can be rotated by a predetermined angle in the main plane.

Further, another part of the upper surface of the bottom plate may be inclined in the opposite direction. As a result, it is possible to support the flat panel detector by tilting it in the reverse direction by bringing the upper surface portion inclined in the reverse direction of the bottom plate and the upper end of the other side plate into contact with the flat plate detector. .

A mobile X-ray apparatus according to another aspect of the present invention includes an X-ray generation unit, a support column that supports the X-ray generation unit, a main body that has a function of controlling the X-ray generation unit, a main body, and a support column. And a dolly mounted. A box for accommodating a flat panel detector for detecting X-rays is provided on the back surface of the main body. The box has a front plate parallel to the back surface of the main body and a bottom plate. At least a part of the top surface of the bottom plate is inclined in the front-rear direction of the main body with respect to the grounding surface of the carriage, and the flat plate type is formed by bringing the inclined top surface of the bottom plate and the front plate into contact with the flat plate detector. The detector is tilted and supported. As a result, the flat detector can be taken out while rotating in the direction perpendicular to the main plane around the upper end of the front plate.

It is desirable that the upper end on the inner space side of the top plate is processed into a curved surface that widens the opening. Thereby, the flat detector can be rotated by a predetermined angle in a direction perpendicular to the main plane with the curved surface as the center.

The box may be configured to have an outer box fixed to the back surface of the main body and an inner box disposed inside the outer box and detachable from the outer box. In this case, the front plate and the bottom plate constitute an inner box. You may provide the handle used when taking out an inner side box from an outer side box in an inner side box. It is preferable that the inner box has a structure that can stand on the floor surface in a state where the inner box is taken out from the outer box at the bottom of the bottom plate.

The outer box may include a plurality of inner boxes arranged in the front-rear direction of the main body. The plurality of inner boxes are preferably configured so that the inclination angles of the bottom plate are different from each other.

It is also possible to provide a control unit space in which a part of the control unit of the main body is mounted in the inner box. It is desirable that a lid that can be opened and closed is attached to an upper portion of the space for the control unit of the inner box. The lid that can be opened and closed may also serve as a handle that is used when the inner box is removed from the outer box.

In still another aspect of the present invention, a method for taking out a flat panel detector from a mobile X-ray apparatus is provided. The mobile X-ray apparatus includes an X-ray generation unit, a support column that supports the X-ray generation unit, a main body that has a function of controlling the X-ray generation unit, and a carriage that mounts the main body and the support column.

In this structure, the flat panel detector can be taken out from the box while rotating in the main plane with one upper end of the side plate constituting the front or rear surface of the main body of the box as a fulcrum. Thereby, it is possible to take out the flat panel detector more easily than a method of lifting the flat detector from the box in the vertical direction.

Hereinafter, specific embodiments of the present invention will be described.

(First embodiment)
The basic structure of the mobile X-ray apparatus of this embodiment will be described with reference to FIGS. Here, a mobile X-ray apparatus using an FPD as a flat panel detector will be described as an example. However, the present invention is not limited to an FPD, but can be applied to an apparatus using an IP cassette or an X-ray film cassette.

FIGS. 1 to 6 are a perspective view, a front view, a left side view, a rear view, a top view, and a bottom view, respectively, showing the mobile X-ray apparatus during movement. 1 to 6, the FPD 5 and the side box 80 and the back box 90 for housing the FPD are removed and are not shown. FIGS. 7A to 7C are a front view, a left side view, and a top view, respectively, showing a form when the mobile X-ray apparatus is used. In FIG. 7, the back box 90 is attached, but the side box 80 is removed and not shown.

As shown in FIGS. 1 to 6, the mobile X-ray apparatus has a carriage 1, a main body 2, a support column 3, and an X-ray generator 4. A main body 2 is fixed to the upper surface of the carriage 1, and a column 3 is supported so as to be rotatable about the axis of the column 3. The cart 1 has a front wheel 11 that is a steering wheel and a rear wheel 12 that is a driving wheel. The rear wheel 12 is rotated by a drive motor built in the main body 2 and can be self-propelled by an operator's operation.

On the upper surface of the main body 2, a display device 30 that displays an input screen of subject information and imaging conditions (tube current, tube voltage, etc.) and a captured image, and an auxiliary column 31 that supports the X-ray generator 4 when moving is supported. Is arranged. A handle 21 is provided at the upper part of the back surface of the main body 2.

Inside the main body 2, in addition to the drive motor described above, a power supply device such as a battery for supplying power to each part of the X-ray apparatus, an irradiation control unit, an image processing unit, and the like are arranged. The irradiation control unit supplies tube current and tube voltage to the X-ray generation unit 4 to irradiate the subject with X-rays, and controls X-ray imaging. The image processing unit receives an image signal from the FPD 5 through wired or wireless communication, generates an X-ray image, displays the X-ray image on the display device 30, and stores it in the storage device. A switch 23 is provided on the back of the main body 2 to instruct the irradiation control unit to start X-ray irradiation.

At this time, the irradiation control unit and the image processing unit can communicate with a notebook computer 93 arranged in a back box, which will be described later, and exchange various information. For example, the irradiation control unit can take in an order list such as subject information and imaging conditions input in advance in the notebook computer 93. The image processing unit can store information such as the generated X-ray image and imaging conditions in a storage device in the notebook computer 93. Furthermore, the image processing unit can process an X-ray image by reading and executing an image processing software program stored in a notebook personal computer. In addition, the irradiation control unit and the image processing unit can communicate with other computers via a network, and exchange various information such as subject information, order lists such as imaging conditions, and X-ray images. .

Therefore, the notebook computer 93 is taken out from the back box 90 before imaging, and an order list such as subject information and imaging conditions is input in advance to the notebook computer 93. After imaging, an X-ray image is acquired from the notebook computer 93. And the like can be read out and transmitted to another computer. It is also possible to perform advanced image processing with the notebook personal computer 93 and other computers. It is also possible to use the notebook personal computer 93 for controlling the FPD 5. If the notebook computer 93 hangs up, it is removed from the back box 90 and reset by pressing the power button.

The support column 3 includes an arm 32 extending horizontally with respect to the support column 3 and a slide mechanism for sliding the arm 32 up and down along the support column 3. The X-ray generator 4 is supported at the tip of the arm 32. The arm 32 may be provided with a mechanism that expands and contracts in the horizontal direction. Moreover, since the support | pillar 3 can rotate with respect to the trolley | bogie 1 centering on the axis | shaft of the support | pillar 3, the arm 32 and the X-ray generation part 4 are extended toward the front of the trolley | bogie 1 like FIG. It can be placed at the desired height of the top.

The X-ray generation unit 4 includes an X-ray tube 41 that generates X-rays and an X-ray diaphragm 42 that limits the irradiation field of the X-rays.

Next, the side box 80 and the FPD 5 will be described with reference to FIGS. FIGS. 8A to 8C are a perspective view, a front view, and a side view showing a part of the carriage 1, a part of the main body 2, the side box 80, and the FPD 5 accommodated therein. 9A to 9C are explanatory views showing the cross-sectional shape of the side surface box 80 and the movable range of the FPD 5 accommodated therein. FIGS. 10A to 10C are explanatory views showing a cross-sectional shape of a side box 80 of another embodiment of the side box 80. FIG. However, in FIG. 9 and FIG. 10, the upper end line of the front plate 81 which is not shown in the sectional views is also shown for reference.

As shown in FIGS. 8 and 9, the side surface of the main body 2 is provided with a side box 80 for accommodating the FPD 5. The side box 80 can accommodate the FPD 5 having a large area (for example, 46 cm on a side). The side box 80 includes a front plate 81 parallel to the side surface of the main body, a bottom plate 82, and

side plates

83 and 84 provided on the left and right of the front plate 81. The bottom plate 82 is inclined in the front-rear direction of the main body 2 with respect to the grounding surface (horizontal plane) of the carriage 1. In the present embodiment, since the upper surface of the carriage 1 is inclined due to the difference in diameter between the front wheel 11 and the rear wheel 12, the bottom plate 82 is disposed in a shape along this, and the bottom plate 82 is inclined. However, the present invention may not have a shape along the top surface of the carriage 1, and the top surface of the bottom plate 82 may be inclined by changing the thickness of the bottom plate 82 as shown in FIG. The front side plate 83 is designed to be lower in height than the rear side plate 84. The FPD 5 is in contact with the inclined upper surface of the bottom plate 82 and the upper end 83a of the front side plate 83, and is supported by the side box in an inclined state.

The distance W between the front side plate 83 and the rear side plate 84 is the distance between the upper end 83a of the front side plate 83 and the lower end 5a of the rear FPD 5 when the largest FPD 5 that can be stored is stored. When r1 is a radius and a circle 91 is drawn around the upper end 83a, the value is designed so as not to touch the circle. As a result, when the operator takes out the FPD 5 from the side box 80, the FPD 5 can be taken out while rotating within the main plane around the upper end 83a of the side plate 83, as shown in FIG. 9B. Even if rotated in this way, the corner of the lower end 5a of the FPD 5 can be taken out from the side box 80 without contacting the side plate 84 on the rear side.

Further, by designing such a distance W, the inclined upper surface of the bottom plate 82 and the upper end 83a of the front side plate 83 are supported in contact with the FPD 5 as shown in FIG. A space 86 is formed between the upper end 84a of the side plate 84 on the rear side and the FPD 5. Due to the presence of this space 86, when the corner of the front end 5b of the inclined FPD hits an obstacle, a force F in the opposite direction to the inclination is applied in the front-rear direction as shown in FIG. 9C. Even so, since the FPD 5 can rotate in the direction opposite to the inclination using the space 86, the impact caused by the application of the force F can be absorbed. Specifically, with the inclined upper surface of the bottom plate 82 and the upper end 83a of the front side plate 83 in contact with the FPD 5, the lower end 5a of the FPD 5 on the rear side plate 84 side is used as a fulcrum, The shock can be absorbed by rotating the FPD 5 by a predetermined angle in the direction of the arrow 87 in the main plane.

9 (a) to 9 (c) and FIG. 10 show a side box in which the FPD 5 is inclined and accommodated on the front side. However, as shown in FIG. 10 (b), the bottom plate 82 is reversed. The FPD 5 may be inclined to the rear side by inclining. Further, as shown in FIG. 10C, a portion in which the upper surface of the bottom plate 82 is inclined to the front side and a portion inclined to the rear side are provided so that the FPD 5 can be inclined in both the front direction and the rear direction. You can also.

The FPD 5 has a configuration in which a semiconductor as an X-ray conversion layer, an electrode for each pixel, a TFT (thin film transistor) substrate, and the like are accommodated in a flat housing. The FPD 5 may have a built-in communication unit for outputting an image signal to the image processing unit of the main body 2 by wireless communication, or may be configured to pass through a cable. At the time of X-ray imaging, it is taken out from the side box 80 and inserted between the subject and the bed. In this state, the FPD 5 receives the X-rays irradiated from the X-ray generation unit 4 and transmitted through the subject, converts the X-rays into image signals, and connects the FPD 5 and the main body 2 via a cable, or And output to the image processing unit of the main body 2 by wireless communication.

Next, the back box 90 disposed on the back of the main body will be described with reference to FIGS. 7B and 8C, FIGS. 8A and 8C, and FIGS. . 11 is a top view of the back box, FIG. 12 is a cross-sectional view taken along the line A-A ′ of FIG. 11, and FIG. 13 is a cross-sectional view of the taken-out inner box. 12 and 13 show a state in which the FPD 5 is inserted.

The rear box includes an outer box 91 fixed to the rear surface of the main body 2 and an inner box 92 that is disposed inside the outer box 91 and can be attached to and detached from the outer box 91. The inner box 92 includes a plurality of

front plates

71a, 71b, 71c parallel to the back of the main body 2, a bottom plate 72,

side plates

73, 74, a back plate 75, and a partition plate parallel to the

side plates

73, 74. 66. As a result, as shown in FIGS. 11 and 12,

spaces

76, 77, 78 having a size corresponding to the size of the FPD 5 and a space 79 suitable for accommodating the notebook computer 93 are configured.

Specifically, the foremost space 76 is a space suitable for accommodating a large FPD 5 having a height of 45.95 cm, and the depth is designed to be about 20 cm. The space 77 is a space suitable for accommodating the small area FPD 5 having a height of 28.15 cm, and the depth is designed to be about 12 cm. The space 78 is designed to have the same depth and different width as the space 77 so that it can be used for other purposes other than the accommodation of the FPD 5.

In the bottom plate 72, the

portions

72a and 72b constituting the bottom surfaces of the

spaces

76, 77 and 78 suitable for accommodating the small area FPD 5 are inclined in the front-rear direction of the main body 2 with respect to the grounding surface (horizontal plane) of the carriage. ing. Thereby, the inclined

upper surfaces

72a and 72b of the bottom plate 72 and the

front plates

71a and 71b are brought into contact with the FPD 5 accommodated in the

spaces

76, 77, and 78, and the FPD 5 is inclined and supported. Thereby, as indicated by an arrow 121 in FIG. 12, the FPD 5 can be easily taken out while rotating in the direction perpendicular to the main plane of the FPD 5 around the upper ends 171a and 171b of the

front plates

71a and 71b. Become.

Further, the upper ends 171a and 171b of the

upper surface plates

71a and 71b are processed into curved surfaces that widen the openings of the

spaces

76, 77, and 78. Thereby, even if the thickness t of the

spaces

76, 77, 78 is small, the FPD 5 can be taken out more easily because the range that can be rotated in the direction perpendicular to the main plane along the curved surface is widened.

In addition, since the openings of the

spaces

76, 77, and 78 are widened by providing the curved surface, the FPD 5 that is held inclined as indicated by the arrow 122 in FIG. 12 can be rotated in the direction opposite to the inclination. Therefore, even when a forward force is applied from the rear direction of the main body 2 to the front end of the FPD 5, the shock can be absorbed by rotating as indicated by the arrow 122.

It is preferable that the space 76 for the FPD 5 and the

spaces

77 and 78 of the inner box 92 are configured so that the inclination angle of the bottom plate 72 is different from each other. Thereby, according to the magnitude | size of FPD5 to accommodate, FPD5 can be inclined to the angle which is easy to take out. Further, the FPD 5 can be inclined at an angle at which the accommodated FPDs 5 do not interfere with each other.

A lid 61 that can be opened and closed is attached to the upper portion of the space 79 for the notebook computer 93 in the inner box 92 via a hinge 62. Due to the lid 61, the notebook computer 93 cannot be seen from the outside. The lid 61 that can be opened and closed includes a handle-like return portion 63 so that it can be used as a handle used when the inner box 92 is taken out from the outer box 91 upward. The notebook personal computer can be taken out by further rotating the lid 61 to open the upper opening of the space 79 as indicated by an arrow 64 in FIG.

At both ends in the left-right direction of the bottom plate 72 of the inner box 92, legs 65 are provided as a structure that can stand on the floor surface with the inner box 92 taken out from the outer box 91 as shown in FIG.

With such a configuration, the inner box 92 can be taken out from the outer box 91 with the return part 63 of the lid 61 as a handle, or can be placed on the floor surface in a state where the FPD 5 or the notebook computer 93 is accommodated. it can. Therefore, the convenience when inputting photographing conditions to a notebook personal computer, taking out image data after photographing, and the like in another place is enhanced.

It is not always necessary to use the handle and the lid 61. For example, as shown in FIG. 14, the front plate 71b is provided with a recess 141, which can be used as a handle.

The procedure for performing imaging in the patient's room using the mobile X-ray apparatus of the present invention described above will be described. As shown in FIG. 1, the operator has a plurality of types of sizes in the side box 80 and the back box 90 of the mobile X-ray apparatus in which the X-ray generator 4 is supported by the column 3 and the auxiliary column 31. Accommodates FPD5. At this time, the operator can lift the back box 90 together with the inner box 92 in a state where the FPD 5 and the notebook computer 93 are accommodated. By moving the handle 21 of the mobile X-ray apparatus, the patient moves in the hospital and is placed on the bedside of the patient's room. The support column 3 is rotated, the X-ray generation unit 4 is arranged above the imaging region of the subject, and the height is adjusted.

The operator takes out the size FPD 5 suitable for photographing from the side box 80 or the back box 90. When taking out from the side box 80, the FPD 5 can be taken out by rotating the FPD 5 around the upper end 83a of the side plate 83 as shown in FIG. 9 (b), so there is no need to lift the FPD 5 upward until it is taken out. Can be taken out easily. When taking out from the back box 90, the FPD 5 can be pulled out while rotating along the curved surface of the upper end 171a of the front plate 71a as indicated by an arrow 121 in FIG.
