Description

  The present invention relates to an X-ray apparatus, and more particularly to an X-ray apparatus that can be easily operated even while caring for a subject.

  The operation of the X-ray TV apparatus is conventionally performed via a remote console or a proximity console. The remote control console is installed in a separate room from the X-ray TV room where the subject is located. While giving instructions on various postures to the subject through the microphone, the table top is moved up and down, left and right, long manual, up and down, The X-ray exposure is performed when turning around the longitudinal direction and reaching the optimum position.

  The proximity console is installed in the X-ray TV room where the subject is located, and the operator gives instructions while looking directly at the subject near the subject. The X-ray exposure is performed when moving to the optimum position and moving around the longitudinal direction, and a normal stand type is used.

  By the way, when the subject is an elderly person with weak legs, it may be necessary to perform an examination while standing next to the tabletop. In addition, even if a child whose language is still not fully understood is a subject, it may be necessary to perform a test while standing next to the tabletop, taking a hand and taking it to the required posture.

  When the examination is performed while the subject is being cared for in this way, if the proximity console is too close, the subject may be disturbed. On the other hand, if the distance is too far, the body of the subject may be supported by one hand in a desired posture, and the other hand may not reach the proximity console.

  As a result, it is necessary to inspect while moving the proximity console, but the stand-type proximity console is quite large and heavy, so it requires a lot of handling and the panel part faces the operator's front. It is also difficult to position. Above all, it is difficult to move the proximity console every time the operator stands.

Therefore, the proximity console can be moved with a small operating force, so that the operator can easily change the orientation of the proximity console to the direction facing itself even if the position touched by the subject changes. For the purpose of providing a movable proximity console, the axis of the fixed axis is placed on the bottom of the monitor platform of the proximity console via a support arm, fixed axis and bearing on a plane almost parallel to the floor surface. Proximity consoles that are supported so as to be rotatable are proposed (for example, see Patent Document 1).
JP 2000-102528 A

  However, even such a proximity console may have to move the entire proximity console, in which case moving a large and heavy proximity console is a cumbersome task. Absent.

  In recent years, some have a tableside console attached to the side of the top plate, and some have a foot switch. Even when such an operating means is used, depending on the posture in which the operator supports the subject with his / her hand, the hand or foot may not reach the position where the operator is placed, and the operation may not be performed.

  On the other hand, in a popular type X-ray apparatus mainly used in a small clinic or the like, a proximity console may be sold as an option and may not be attached. In this case, the examination cannot be performed while the subject is being cared for.

  The present invention has been made in consideration of the above-described circumstances, and an object of the present invention is to provide an X-ray apparatus that can be easily operated while caring for a subject.

  In order to solve the above-described problem, an X-ray apparatus according to the present invention includes a top plate on which a subject is placed, and a tilting, lateral movement, and long manual operation of the top plate. A bed that drives vertical movement and rotation around the longitudinal length, an X-ray tube that is disposed with the top plate sandwiched therebetween and that emits X-rays, a detector that detects the exposed X-rays, and both ends thereof A C-type arm that supports the X-ray tube and the detector oppositely, a drive unit that drives rotation, vertical movement, and long manual movement of the C-type arm, and a control unit that controls the operation of the bed and the drive unit And an operation console that outputs a driving operation signal of the bed and the driving unit to the control unit, the X-ray apparatus is configured to be communicable with the control unit, Among the functions assigned to each, it has a plurality of switches programmed to achieve the desired function and operates. Who are those with a portable operating device.

  The X-ray apparatus according to the present invention can be easily operated even while caring for a subject.

  Embodiments of an X-ray apparatus according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows a layout example of an X-ray examination room E in which an X-ray apparatus 1 according to the present invention is installed. The X-ray examination room E is divided into an X-ray television room T and an operation room OR by a partition wall W.

  An apparatus main body 2 of the X-ray apparatus 1 is installed in the approximate center of the X-ray television room T, and a proximity console 3 is arranged in the vicinity of the apparatus main body. Moreover, the high voltage generator 4 and the system cabinet 5 are juxtaposed along one wall surface. The operation device 6 is hung on the neck of the operator OP via a strap.

  On the other hand, a remote console 7 and an arithmetic processing unit 8 are installed in the operation room OR. Further, the service unit 9 is temporarily brought in when the X-ray apparatus 1 is installed. This service unit 9 assigns programs for executing the respective functions to the switches of the proximity console 3, the remote console 7, and the operation device 6, and can be carried like a notebook computer. A display unit such as a display and an input unit such as a keyboard and a mouse are provided.

  The apparatus body 2 includes a top plate 11 on which the subject is placed, an X-ray tube 12 for exposing the subject to X-rays across the top plate 11, and a subject at the bottom. A detector (not shown) for detecting the X-rays transmitted through is disposed. The X-ray tube 12 and the detector are opposedly supported at both ends of the C-arm 13.

  The top plate 11 is tilted up and down around the short direction (Y direction in FIG. 1), moved left and right along the short direction, and slid along the long direction (X direction in FIG. 1). Long manual movement, vertical movement sliding in the vertical direction (Z direction in FIG. 1, direction perpendicular to the paper surface), and rotation around the longitudinal direction are possible. These are driven by a motor provided in a bed 14 that supports the top plate 11.

  Further, the C-shaped arm 13 can rotate around Y, move up and down in the Z direction, and perform long manual movement in the Y direction. These movements are driven by a motor provided in the drive unit 15 on the back surface of the C-arm 13. The motors in the bed 14 and the drive unit 15 are controlled by a control unit (not shown) provided in the drive unit 15.

  The control unit 15 is connected to the proximity console 3, the remote console 7, and the operation device 6 through a communication cable, and the bed 14 and the control unit 15 are connected to the control unit 15 from the proximity console 3, the remote console 7, or the operation device 6. A signal for operating the drive of the motor in the drive unit 15 is output.

  As shown in FIG. 2, the operation device 6 is a small one having a shape and size similar to that of an IC recorder, and can be stored in a breast pocket by a clip 24 or hung from a neck via a strap 25. it can. Therefore, it is not necessary to hold it while not in use.

  A plurality of switches 21 and a display unit 22 are disposed on the front surface of the operation device 6. Of the many switch functions of the proximity console 3 and the remote console 7, typical functions that are frequently used during inspection are assigned to the switch 21.

  As a result, the number of operations performed via the proximity console 6 is drastically reduced. Therefore, even when the examination is performed while the subject is being cared for, even if the proximity console 3 is placed some distance away, the examination can be performed. There is no hindrance and does not interfere with the care of the subject. Even when the subject's body is supported by one hand in a desired posture, the operation device is always close to the user, so that the operation device does not reach the hand. Note that the switch 21 is formed of a push button in this embodiment, but may be a slide bar or a jog dial.

  The display unit 22 is a liquid crystal display, for example, and displays which function is assigned to which switch. Each time the display changeover switch 23 provided on the side of the operation device 6 is pressed, the function of the switch 1, the function of the switch 2, and so on are toggled together with the switch number.

  The operation device 6 is configured to be capable of remote operation by communication with the apparatus main body 2 and is connected to the control unit in a wired manner via a communication cable 26 as shown in FIG. Further, the operation device 6 can be in a wireless communication mode.

  In the wired case, a cord suspension arm for avoiding contact of the cord with the floor and a cord accommodation function such as a cord reel function may be required. On the other hand, in wireless, 1) When moving with the operation device 6, it does not affect peripheral devices, etc. 2) Since the wire does not contact the subject, the subject does not feel uncomfortable 3) There is no cord Therefore, it is superior in terms of movement and operability compared to wired, such as being preferable in terms of hygiene without any cord contact with the floor.

  The X-ray apparatus 1 according to the present embodiment is configured as described above, and a procedure for assigning a function to each switch 21 of the operation device 6 will be described below. FIG. 3 shows an example of a window displayed on the display unit of the service unit 9 when a function is assigned to each switch 21 of the operation device 6.

  First, the operator OP selects one of the switches 21 of the operation device 6 by clicking one of the switches displayed on the screen using a mouse or the like. At this time, the selected switch is highlighted by bright / dark reversal, highlighting, flashing, or the like.

  Next, the operator OP selects a task (function) given to each switch. On this screen, typical tasks (functions), such as raising / lowering, longitudinal movement, vertical movement, and exposure, are displayed and can be selected from these. Alternatively, “do nothing” can be selected in which no task is given to the switch 21.

  If you want to select a task other than the one displayed here, select “Other” and click the “Select Function” button to bring up another window and list other functions on the screen. You can choose from.

  In this way, for example, the first switch 21 causes the “up” movement of the top plate, the second switch 21 causes the “top” movement of the top plate, and the third switch 21 indicates the longitudinal direction “ The “front” movement, the fourth switch 21 in the longitudinal direction “backward” movement, the fifth switch 21 in the “upward” movement of the top board, and the sixth switch 21 in the top board movement The “downward” movement can be set so that “exposure” is assigned to the seventh switch 21 and no function is given to the eighth switch 21.

  In this case, the top plate rotates in the standing direction while the first switch 21 is kept pressed, and when the finger is released from the first switch 21, the movement stops there. Conversely, while the second switch 21 is kept pressed, the top plate rotates in the inverted direction, and when the finger is released from the second switch 21, the movement stops there. In this way, it is possible to set a continuous operation or an operation that completes the operation at the moment when it is pushed like exposure.

  The above shows a method of assigning a function to each switch 21 of the operation device 6 when the X-ray apparatus is installed on the site. Even if a function is assigned to each switch 21 in this way, there is a case where it is desired to change the function assigned to each switch 21 depending on the examination site of the subject. At this time, if the service unit is carried in again and connected, the setting cannot be changed flexibly. Therefore, hereinafter, a method for changing the setting of the function assigned to each switch 21 will be described with reference to FIGS. FIG. 4 is a perspective view showing a panel portion of the proximity console 3, and FIG. 5 is a flowchart showing a process of changing a function assigned to each switch of the operation device.

  As shown in FIG. 4, the proximity console 3 is provided with a large number of switches such as a joystick 31, a lever 32, and a push button 33. Of these, one push button 33 is set as a program switch.

  The program switch is a button for entering a mode in which each switch 21 can change a program set to realize a desired function. When this program switch is turned on (step S1 in FIG. 5), the bed 14 In addition, switches such as the drive unit 15 and exposure are locked (step S2). Thereby, when in the setting mode, even if the switch is touched by mistake, the X-ray apparatus 1 does not work and the subject and the operator OP are not exposed to danger.

  In this state, as shown by an arrow in FIG. 4, the raising lever 32 of the proximity console 3 is pulled to the “tilting” side (step S3 in FIG. 5), and the desired switch 21 of the operation device 6 is pulled while being pulled. When is pressed (step S4), the operation of “topping” the top plate is assigned to the switch 21 (step S5).

  This is repeated until the desired setting is completed (steps S3 to S5), and when completed, the program switch is turned off (step S6). As a result, the locks of the switches such as the bed 14, the drive unit 15, and the exposure are released, and the normal inspection mode is restored.

  As described above, since the function set in each switch 21 of the operation device 6 can be changed without a special device such as the service unit 9, the function change can be made easily and flexibly.

  The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, but these embodiments are also included in the scope of the present invention.

  For example, in the present embodiment, the case where the operation device 6 has eight switches has been described as an example. However, the number of switches is not limited to this, and the number can be increased or decreased.
