For example, a rail is installed on the support column 2, and the arm 3 slides up and down by moving on the rail with one end connected to the rail. Further, the arm 3 expands and contracts in a direction perpendicular to the long axis of the support column 2. That is, the arm 3 is retracted when the X-ray tube 4 is retracted and retracted so that the X-ray tube 4 does not protrude, and is expanded so that the X-ray tube 4 reaches farther when capturing the X-ray image. .

  The X-ray tube 4 is connected to a high voltage generator (not shown) included in the apparatus main body 9 and generates X-rays using a high voltage supplied from the high voltage generator. The X-ray movable diaphragm 5 has a mechanism for adjusting an irradiation field of X-rays generated by the X-ray tube 4. Specifically, the X-ray movable diaphragm 5 has two pairs of movable restriction blades, and the X-ray irradiation field is adjusted by opening and closing the movable restriction blades in each pair. That is, the movable restricting blade 5 is opened and closed so that the X-ray emitted in a conical shape by the X-ray tube 4 is irradiated to a predetermined irradiation field.

  The front wheel 6 is a turnable wheel, for example, a pair of casters. The rear wheel 7 is a drive wheel to which a motor or the like (not shown) is connected, and is driven according to an operation by an operator. For example, the rear wheel 7 is driven by a motor when a predetermined pressure is detected by a pressure sensor provided on an operation handle 8 described later, or a drive button disposed near the operation handle 8 is pressed. And driven by the power of the motor. The operation handle 8 is a handle that is operated when the operator moves the mobile X-ray diagnostic apparatus 1. Details of the operation handle 8 will be described later.

  The apparatus main body 9 includes a control unit that controls each unit of the mobile X-ray diagnostic apparatus 1, a storage unit that stores various data, a battery that stores electric power supplied from the outside, an operation unit that receives various operations, and various types. A display unit for displaying the information. The apparatus main body 9 executes control of various processes relating to movement of the mobile X-ray diagnostic apparatus 1 and various processes relating to imaging of X-ray images. For example, the apparatus main body 9 controls the high voltage generation unit according to the operator's instruction transferred from the operation unit arranged on the upper surface of the apparatus main body 9 and adjusts the voltage supplied to the X-ray tube 4, thereby The X-ray dose and ON / OFF to be controlled are controlled. In addition, for example, the apparatus main body 9 controls the X-ray movable diaphragm 5 in accordance with an instruction from the operator, and adjusts the opening of the movable limiting blade of the X-ray movable diaphragm 5 so as to irradiate the patient with X. Control the field of radiation.

  In addition, the apparatus body 9 controls image data generation processing, image processing, analysis processing, and the like in accordance with an operator's instruction. In addition, the apparatus main body 9 controls to display a GUI for receiving an operator's instruction, an image stored in the storage unit, and the like on the display of the display unit. Further, the apparatus main body 9 drives a built-in motor in accordance with the pressure detected by the pressure sensor provided on the operation handle 8 or the operation received by the push button, and the rear wheel 7 is driven by the power of the motor. Drive. In addition, the apparatus main body 9 performs control so that the brake is applied when the pressure is detected by the pressure sensor or the pressing of the pressing button is stopped. Here, the apparatus main body 9 controls the apparatus main body 9 based on the position of the operation handle 8. This will be described later.

  Here, the operation handle 8 according to the first embodiment is configured to make it possible to improve convenience when using the apparatus. Hereinafter, an example of the flow of X-ray image capturing using the mobile X-ray diagnostic apparatus 1 will be described. For example, the mobile X-ray diagnostic apparatus 1 is placed in a hallway or the like on each floor of a hospital during standby, and is charged according to the storage capacity of the battery. In use, the mobile X-ray diagnostic apparatus 1 is unlocked with a dedicated key or the like, and is moved by an operator to a hospital room or an operating room.

  When the operator moves to the hospital room, the operator turns the column 2 around the longitudinal direction as shown in FIG. 1B to move the X-ray tube 4 and the X-ray movable diaphragm 5 to the front of the apparatus main body 9. Turn to. Then, the operator extends the arm 3 and arranges the X-ray tube 4 at a position where X-rays are irradiated to the imaging region of the patient. Here, the operator uses a switch, a knob, or the like provided in the X-ray movable diaphragm 5 to adjust the imaging region to enter the irradiation field. Then, an image recording medium such as an FPD (Flat Panel Detector) or a cassette is set between the imaging region of the patient and the bed, and an X-ray image is taken.

  As described above, the mobile X-ray diagnostic apparatus 1 is moved to a hospital room or an operating room where a patient is present during use, and an X-ray image is taken by adjusting the position and irradiation field of the X-ray tube 4 with respect to the imaging region. Is done. However, in the case of a conventional mobile X-ray diagnostic apparatus, convenience may be reduced when the apparatus is used. FIG. 2 is a diagram illustrating an example of a mobile X-ray diagnostic apparatus according to the related art. For example, in the mobile X-ray diagnostic apparatus according to the related art, for example, as shown in FIG. 2, an operation handle 20 is provided on the rear side (rear wheel side) of the mobile X-ray diagnostic apparatus.

  In the conventional mobile X-ray diagnostic apparatus provided with such an operation handle 20, the operator grasps the operation handle 20 with both hands and pushes or pulls the mobile X-ray diagnosis. Move the device. For example, the operator holds the operation handle 20 from the operation handle 20 side toward the mobile X-ray diagnostic apparatus side (towards the left direction in the figure), and pushes or pulls the apparatus to a room or surgery. Move to room. Then, the operator takes an X-ray image by performing various processes as described above.

  Here, in the conventional mobile X-ray diagnostic apparatus, as shown in FIG. 2, since the operation handle 20 has a shape protruding from the apparatus main body, there is a case where it is obstructive except during movement. In some cases, the convenience of using the apparatus is reduced. As described above, the mobile X-ray diagnostic apparatus is used in a narrow hospital room, or used in an operating room or the like in which various devices are placed and a doctor, a nurse, a technician, or the like performs various actions. In such a case, the handle portion protruding from the apparatus gets in the way.

  Further, in the conventional mobile X-ray diagnostic apparatus, the height of the operation handle 20 cannot be easily adjusted, and the convenience when using the apparatus may be reduced. For example, in a conventional mobile X-ray diagnostic apparatus, there is known a mobile X-ray diagnostic apparatus capable of adjusting the height by removing a screw of the operation handle 20 fixed by a screw. However, in the case of such a mobile X-ray diagnostic apparatus, the operator removes the screw and adjusts the height of the operation handle 20 each time it is used, and the height cannot be easily adjusted. Convenience decreases.

  In addition, such a mobile X-ray diagnostic apparatus is provided with a function of assisting traveling according to the operation of the operator when the operation handle 20 is operated to move the apparatus. For example, the operation handle 20 is provided with a pressure sensor, and when the operator grips and pushes or pulls the operation handle 20, control is performed so that the device travels in the direction in which the device is pushed or pulled. Assist function is provided. Here, in the conventional mobile X-ray diagnostic apparatus, as described above, the operation handle 20 is operated after the lock is released with a dedicated key or the like and the vehicle can run. However, in the conventional mobile X-ray diagnostic apparatus, when the operation handle 20 protruding from the apparatus placed in the unlocked state is erroneously operated, the apparatus malfunctions. There is also.

  Therefore, the mobile X-ray diagnostic apparatus 1 according to the first embodiment is configured to improve convenience when using the apparatus. Specifically, the operation handle 8 according to the first embodiment is provided so that the position with respect to the apparatus main body 9 can be changed. Then, a control unit included in the apparatus main body 9 controls predetermined processing based on the state of the operation handle 8. More specifically, the operation handle 8 is provided so as to be changeable between a position stored in the apparatus main body 9 and a position where the operation handle 8 is gripped and operated by the operator. Then, the control unit of the apparatus main body 9 controls the apparatus main body 9 so that the apparatus main body 9 cannot travel when the position of the operation handle 8 is changed to the position stored in the apparatus main body 9. Control is performed so that the apparatus main body 9 can travel when the position is changed to a position where the operator grips and travels.

  FIG. 3A is a diagram for explaining an example of the operation handle 8 and the control unit 10 according to the first embodiment. For example, as shown in FIG. 3A (A), the operation handle 8 is held by the operator and operated, and as shown in FIG. 3A (B), the operation handle 8 is stored in the apparatus main body 9. The position can be changed. Here, the control unit 10 provided in the apparatus main body 9 performs control so that the apparatus main body 9 can run when the operation handle 8 is in the state shown in FIG. 3A (A). In the state shown in (B), control is performed so that the apparatus main body 9 cannot travel.

  For example, in the mobile X-ray diagnostic apparatus 1 according to the first embodiment, when the operation handle 8 is provided with a pressure sensor, the control unit 10 operates as shown in FIG. 3A (A). Only when 8 is in a position operated by the operator, the vehicle is controlled to travel according to the operation by the operator. That is, the control unit 10 controls the motor so that the rear wheel 7 is driven in a direction corresponding to the pressure direction detected by the pressure sensor in the state shown in FIG. 3A (A). On the other hand, when the operation handle 8 is in the state shown in FIG. 3A (B), the control unit 10 does not drive the motor even when the pressure is detected by the pressure sensor of the operation handle 8. Control is performed so that the rear wheel 7 is not driven.

  The travel control is not limited to the direct control for the motor described above, and may be controlled by an arbitrary method. For example, when the rear wheel 7 is provided with a brake and the operation handle 8 is in the state shown in FIG. 3A (A), the control unit 10 performs control so as to release the brake, and the operation handle 8 is shown in FIG. In this state, the control unit 10 may perform control so as to maintain the braked state.

  Further, any method can be used to determine whether the operation handle 8 is in a position operated by the operator or in a stored position. For example, when a push switch is provided in a storage portion in which the operation handle 8 is stored, and the operation handle 8 is stored and the press switch is pressed, the control unit 10 determines that the operation handle 8 is in a position to be stored. And it may be a case where control is performed so that the apparatus main body 9 cannot travel. In such a case, when the push switch is not pressed, the control unit 10 determines that the operation handle 8 is at the position to be operated, and performs control so that the apparatus main body 9 can run.

  Alternatively, the control unit 10 may perform control according to the inclination of the operation handle 8. In such a case, for example, when the operation handle 8 is provided with an angle sensor and the change from the reference angle exceeds a predetermined threshold with reference to the angle of the state in which the operation handle 8 is stored, the control unit 10 Alternatively, it may be determined that the operation handle 8 is in a position to be operated and the apparatus main body 9 is controlled to be able to travel. In such a case, when the change from the reference angle does not exceed the predetermined threshold, the control unit 10 determines that the operation handle 8 is in the stored position and determines that the apparatus main body 9 cannot travel. Control to be. Note that the above-described example is merely an example, and an arbitrary method can be used to determine whether the operation handle 8 is in a position operated by the operator or in a stored position.

  Here, the position of the operation handle 8 according to the first embodiment is changed so that the gripped portion gripped by the operator has an arbitrary height. FIG. 3B is a perspective view of the mobile X-ray diagnostic apparatus 1 according to the first embodiment shown in FIG. 3A. As shown in FIG. 3B, the mobile X-ray diagnostic apparatus 1 includes a storage portion 9a, a tray 9b, and an operation unit 9c on the upper surface of the apparatus body 9. Then, the operation handle 8 moves up and down in the direction indicated by the arrow 31. Here, the operation handle 8 is provided so as to be fixed at an arbitrary height within the movable range indicated by the arrow 31. For example, a gas pressure type lifting mechanism is installed at the base portion of the operation handle 8, and a push switch, a lever, or the like is provided at the operation portion of the operation handle 8 (the lateral handle on the front side in the figure). Then, for example, while the operator is pressing the push switch or operating the lever, the stopper of the lifting mechanism is removed, and the operation handle 8 is raised in the direction above the arrow 31 by the gas pressure, When the push switch is pressed or the lever operation is stopped, a stopper is applied, and the operation handle 8 may be fixed at that position.

  In such a case, the operator can adjust the height of the operation handle 8 to a desired height by operating the push switch or the lever while holding the grip portion of the operation handle 8. Note that the above-described example is merely an example, and any existing technology can be applied to the mechanism for adjusting the height of the operation handle 8. The tray 9b shown in FIG. 3B is a storage portion for placing a remote controller for remotely operating the apparatus main body 9, a pen, or the like, or leaning a medical chart. The operation unit 9c illustrated in FIG. 3B is a touch panel that displays various GUIs and receives various operations by the operator. For example, the operation unit 9c receives various settings related to X-ray imaging.

  As described above, the operation handle 8 according to the first embodiment is provided so that the position of the operation handle 8 can be changed with respect to the apparatus main body 9, and the control unit 10 controls the travel of the apparatus main body 9 according to the position of the operation handle 8. To do. Thereby, the mobile X-ray diagnostic apparatus 1 according to the first embodiment can improve convenience when the apparatus is used. FIG. 4 is a diagram for explaining an example of use of the mobile X-ray diagnostic apparatus 1 according to the first embodiment.

  For example, in the mobile X-ray diagnostic apparatus 1, as shown in FIG. 4A, when the apparatus is to be moved, the operator operates the operation handle 8 fixed to a desired height. Then move them to a hospital room or operating room. Here, since the control unit 10 is in a position where the operation handle 8 is operated, the control unit 10 controls the built-in motor so as to move in a direction corresponding to the direction of the pressure applied to the operation handle 8. Then, after moving to a hospital room such as a hospital room or operating room, as shown in FIG. 4B, when the operation handle 8 is stored by the operator, the control unit 10 cannot run the apparatus main body 9. Control to be Further, the operation handle 8 may be controlled by the control unit 10 so as to be automatically positioned in the storage state. That is, the control unit 10 may control the position of the operation handle 8 when the apparatus main body 9 is stopped, and may be in the retracted state as shown in FIG. As a result, even if the operator is not conscious of the state of the operation handle 8, the position of the operation handle 8 can be suitably controlled according to the travel / stop state of the apparatus main body 9.

  Thereby, for example, when the mobile X-ray diagnostic apparatus 1 is used in a hospital room or an operating room, the operation handle 8 is not in a state of protruding from the apparatus, so that an object is not caught on the operation handle 8. It is possible to prevent the doctor, nurse, engineer, etc. working around the device from getting in the way. Further, since the operation handle 8 is housed, it is not obstructed when the operation unit 9c is operated, and it is easy to check the captured image. Therefore, X-ray imaging using the mobile X-ray diagnostic apparatus 1 can be performed skillfully, and the time required for X-ray imaging can be shortened to reduce the load on the patient.

  In addition, after the X-ray imaging shown in FIG. 4B is completed, the operation handle 8 is erroneously operated by placing the operation handle 8 in a retracted state when waiting in a hallway or the like of a hospital floor. Malfunction can be suppressed. That is, in the mobile X-ray diagnostic apparatus 1 according to the first embodiment, an operator who is familiar with the operation method of the apparatus that the traveling of the apparatus is controlled by the position of the operation handle 8 will move the apparatus. Unless this is the case, the apparatus main body 9 cannot be run, and safety can be improved.

  As described above, in the mobile X-ray diagnostic apparatus 1 according to the first embodiment, the position of the operation handle 8 operated by the operator when the apparatus main body 9 is to be moved is defined as the operated position. It is possible to change the position depending on the position of the housed state, and by associating each position with the control related to traveling, the apparatus can be surely identified when moving and when not moving, and can execute control corresponding to that. .

For example, as shown in FIG. 5A, the operation handle 8 according to the first embodiment is provided with a support portion perpendicular to the grip portion gripped by the operator, and the support portion is housed inside the apparatus main body 9. As a result, the gripping portion moves in the direction of the arrow 32. Also in the operation handle 8 shown in FIG. 5A, the grip portion can be fixed at an arbitrary height. In the operation handle 8 shown in FIG. 5A, in the direction indicated by the arrow 32, the state where the operation handle 8 is at the lower end is in the retracted state, and the state where it is raised from the lower end is in the operated position.

  In the above-described example, the example in which the operator grips the operation handle 8 in the horizontal direction has been described. However, the embodiment is not limited to this, and for example, the operator may hold in the vertical direction. A simple operation handle 8 may be used. For example, in the operation handle 8 according to the first embodiment, as illustrated in FIG. 5B, grip portions that the operator grips in the vertical direction are provided at both ends of the upper surface of the apparatus main body 9. Then, the operation handle 8 moves in the direction of the arrow 33 with respect to the apparatus main body 9. That is, in the example of FIG. 5B, the grip portion is housed inside the apparatus main body 9.

  As described above, the operation handle 8 according to the first embodiment can have various shapes, but the examples shown in FIGS. 5A and 5B are only examples. That is, the operation handle 8 can have an arbitrary shape other than the above-described example.

  As described above, according to the first embodiment, the operation handle 8 is provided such that its position relative to the apparatus main body 9 can be changed. The control unit 10 controls predetermined processing based on the state of the operation handle 8. Therefore, the mobile X-ray diagnostic apparatus 1 according to the first embodiment can execute processing associated with the position of the operation handle 8 and can improve convenience when using the apparatus. .

  Further, according to the first embodiment, the operation handle 8 is provided so as to be changeable between a position stored in the apparatus main body 9 and a position where the operation handle 8 is gripped and operated by the operator. The control unit 10 performs control so that the apparatus main body 9 cannot travel when the position of the operation handle 8 is changed to the position stored in the apparatus main body 9, and the position of the operation handle 8 is adjusted by the operator. Control is performed so that the apparatus main body 9 can travel when it is changed to the position to be gripped and traveled. Therefore, the mobile X-ray diagnostic apparatus 1 according to the first embodiment can control traveling by distinguishing between moving time and non-moving time, and can improve safety.

  Further, according to the first embodiment, the position of the operation handle 8 is changed so that the gripped portion gripped by the operator has an arbitrary height. Therefore, the mobile X-ray diagnostic apparatus 1 according to the first embodiment enables the operator to operate with an easy-to-operate posture.

  Further, according to the first embodiment, the operation handle 8 is provided with a pressure sensor that receives an operation for controlling the travel of the apparatus main body 9. Therefore, the mobile X-ray diagnostic apparatus 1 according to the first embodiment makes it possible to easily move the apparatus.
