  Hereinafter, embodiments of a mobile X-ray diagnostic apparatus will be described in detail with reference to the accompanying drawings. In the following, a mobile X-ray diagnostic apparatus according to the present application will be described by taking as an example a mobile X-ray diagnostic apparatus in which a support column is used for a support mechanism that supports an X-ray tube and an X-ray movable diaphragm.

(First embodiment)
First, an example of the overall configuration of the mobile X-ray diagnostic apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of the overall configuration of a mobile X-ray diagnostic apparatus 1 according to the first embodiment. 1A shows a state when the X-ray tube is stored, and FIG. 1B shows a state when an X-ray image is taken. As shown in FIG. 1A, the mobile X-ray diagnostic apparatus 1 includes a column 2, an arm 3, an X-ray tube 4, an X-ray movable diaphragm 5, a front wheel 6, a rear wheel 7, A handle 8 and an apparatus main body 9 are provided.

  As shown in FIG. 1A, the support column 2 is disposed on the front side (front wheel 6 side) of the mobile X-ray diagnostic apparatus 1, and supports the arm 3 by connecting one end of the arm 3. One end of the arm 3 is connected to the support column 2, and an X-ray tube 4 and an X-ray movable diaphragm 5 are disposed at the other end. Here, the arm 3 is connected by the support column 2 so as to slide freely up and down. 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.

  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 the 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 driven by pressing a drive button disposed near the handle 8 and driven by power from the motor. The handle 8 is a handle that is operated when the operator moves the mobile X-ray diagnostic apparatus 1. For example, the operator can move the mobile X-ray diagnostic apparatus 1 forward or backward by pressing the drive button while holding the handle 8. Alternatively, the handle 8 includes a pressure sensor, and detects the direction operated by the operator (for example, when the handle is pushed, when the handle is pushed, when the handle is pulled, etc.) and drives the motor in a desired direction. It is also possible to make it. Note that the mobile X-ray diagnostic apparatus 1 is controlled so as to be braked when the above-described driving button is stopped or when detection by the pressure sensor is lost.

  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. 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 by a dedicated key or the like, and the operator operates the handle 8 and drives the rear wheel 7 by a drive button (or a pressure sensor or the like). It is moved to the hospital room.

  When the operator moves to the hospital room, as shown in FIG. 1B, the operator rotates the support column 2 around the longitudinal direction 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. As an image recording medium, an FPD (Flat Panel Detector), a cassette or the like is set between the imaging region of the patient and the bed.

  As described above, the mobile X-ray diagnostic apparatus 1 is moved to the patient room where the patient is in use, and the position and irradiation field of the X-ray tube 4 are adjusted with respect to the imaging region. Such a mobile X-ray diagnostic apparatus 1 is configured to improve the operability of the imaging. Specifically, the mobile X-ray diagnostic apparatus 1 according to the first embodiment improves the operability of imaging by improving the operability of the X-ray movable diaphragm 5.

  Hereinafter, prior to description of a configuration related to improvement in operability related to shooting, a case where operability related to shooting in the related art is lowered will be described. FIG. 2A is a diagram illustrating an example of the X-ray tube 4 and the X-ray movable diaphragm 5 according to the related art. FIG. 2A shows a view when the X-ray tube 4 and the X-ray movable diaphragm 5 are viewed from the direction opposite to the column 2. As shown in FIG. 2A, the X-ray movable diaphragm 5 according to the prior art is provided with a knob for adjusting the opening degree of the movable restricting blade, an illumination switch, and the like. That is, the operator rotates the two knobs while turning on the illumination lamp that illuminates the X-ray irradiation field adjusted by the movable restricting blade, while visually confirming the X-ray irradiation field. The position of the X-ray tube 4 and the opening degree of the movable restricting blade can be adjusted.

  For example, the operator adjusts the position and orientation of the X-ray tube 4 while holding the diaphragm handle 10 shown in FIG. 2A. Further, the operator adjusts the opening degree of the movable restricting blade with a knob provided on the X-ray movable diaphragm 5. Here, as shown in FIG. 2A, the diaphragm handle 10 according to the prior art is disposed on each side surface of the X-ray movable diaphragm 5 on the front surface (surface on which knobs, switches, and the like are disposed). Therefore, when operating the front face of the X-ray movable diaphragm 5 facing the front, the adjustment of the X-ray tube 4 while holding the handle 10 and the movement limitation by the knob provided on the front face of the X-ray movable diaphragm 5 are performed. It is easy to adjust the opening degree of the blades and the operability is good. However, when the operation is performed in the same direction as the front surface of the X-ray movable diaphragm 5, the distance to the handle 10 may be long, or the operation may not be performed while visually recognizing the knob.

  FIG. 2B is a diagram illustrating an example of a state of operation of the X-ray movable diaphragm 5 according to the related art. As described above, since the mobile X-ray diagnostic apparatus is used by moving to a hospital room or the like, there is not always enough space for taking an X-ray image, and the mobile X-ray diagnostic apparatus is a narrow space as shown in FIG. 2B. It may be required to operate. For example, as shown in FIG. 2B, a bed where a patient is sleeping and a wall of a hospital room are close (or various devices connected to the patient are arranged), and the mobile X-ray diagnostic apparatus is connected to the bed. Since there is not enough space on the side opposite to the side on which the X-ray is disposed, it may be difficult to operate the X-ray movable diaphragm 5 directly facing the front surface.

  In such a case, as shown in FIG. 2B, the X-ray movable diaphragm 5 is operated from the back side (the surface facing the surface on which the knobs, switches, etc. are arranged). As a result, an operator (especially a woman with a short height, etc.) operates the diaphragm handle 10 at a distant position or operates without visually recognizing a knob, a switch, etc., and the operability is lowered. In addition, since the aperture handle 10 is at a far position, there are cases where the front handle is gripped and operated during storage.

  In order to deal with such a problem, a conventional technique in which a handle that can be easily grasped from the front surface and the back surface of the X-ray movable diaphragm 5 is arranged in the X-ray tube 4 is known. However, in such a conventional technique, it is difficult to adjust the X-ray movable diaphragm 5 while grasping the handle, and the operability is lowered. FIG. 3 is a diagram for explaining an example of a problem related to the related art. As described above, the mobile X-ray diagnostic apparatus is often used in a narrow hospital room, and there are many cases where the placement of the apparatus in the hospital room is limited. For example, as shown in FIG. 3, a mobile X-ray diagnostic apparatus must be placed on the side of the bed where the patient is sleeping as shown in the figure. When the handle 5 is disposed in the X-ray tube 4 when the 5 is rotated and disposed as shown in FIG. 3, the operability such as the rotation operation of the X-ray movable diaphragm 5 is degraded.

  In addition, a conventional technique for arranging a ring-shaped handle on the X-ray movable diaphragm 5 is known, but in this conventional technique, the ring-shaped handle is enlarged so as to surround the X-ray movable diaphragm 5. In other words, the storage may be hindered or the operator may feel a sense of pressure during use. In addition, if the ring-shaped handle surrounds the X-ray movable diaphragm 5, the visibility of the knobs and switches arranged on the side surface of the X-ray movable diaphragm 5 is reduced, and as a result, the operability is improved. Will be reduced.

  As described above, in the related art, the operability for photographing may be deteriorated. Therefore, the mobile X-ray diagnostic apparatus 1 according to the present application improves the operability of imaging by improving the operability of the X-ray movable diaphragm 5. Hereinafter, the configuration of the X-ray movable diaphragm 5 according to the first embodiment will be described with reference to FIGS. 4A to 4E. 4A to 4E are diagrams illustrating an example of the configuration of the X-ray movable diaphragm 5 according to the first embodiment.
