Some have In addition, a high-voltage power supply device and a battery are built in the movable carriage that holds the X-ray generation unit. For this reason, it can be used with a mobile X-ray imaging apparatus and a film that obtains an image by detecting X-rays, a CR (Computed Radiography) IP (Imaging Panel) cassette, or a digital X-ray detector using a semiconductor sensor. X-ray photography in general hospital rooms is possible. In some cases, the main body is provided with a second monitor and a monitor in the vicinity of the X-ray tube, and information related to imaging can be displayed.

  However, for example, during X-ray imaging, a monitor provided in the vicinity of the X-ray generation unit moves together with the X-ray generation unit above, below, to the side, etc. of the subject. Therefore, depending on the position of the X-ray generation unit, it may be difficult for the operator to confirm information displayed on a monitor provided near the X-ray generation unit.

  FIG. 1 is an external view showing a moving X-ray imaging apparatus according to an example of the embodiment at the time of movement. 1 shows a configuration of an embodiment of a mobile X-ray imaging apparatus to which the present invention is applied. In an embodiment described later, a radiation generation apparatus that can be moved by a carriage or the like is referred to as a mobile X-ray imaging apparatus, a mobile X-ray imaging apparatus, or a mobile X-ray generation apparatus. Actual imaging, that is, detecting X-rays from an X-ray imaging apparatus to obtain an X-ray image is a portable digital X-ray detector using a film, a CR IP cassette, a semiconductor X-ray image sensor, etc. Imaging unit. In particular, the digital X-ray detector can be provided with a wireless communication unit and a wired communication unit that transmit the obtained digital X-ray image to the system control unit 2. The mobile X-ray imaging apparatus and the imaging unit may be collectively referred to as a mobile X-ray imaging system.

  Below the movable carriage 1, wheels for transmitting driving force and casters capable of changing direction are attached. A support column is vertically suspended above the arm, and an arm is cantilevered via a fixture, and an X-ray tube and a collimator for generating X-rays are attached. A support member that holds the X-ray tube and the collimator is formed on the mobile X-ray round-the-wheel. Casters and drive wheels are attached to the movable carriage and can move. An operator can hold the grip portion 11 and move the entire apparatus.

  The second monitor 10 displays information related to X-ray imaging. For example, in the case of an X-ray imaging apparatus having a system control unit 2 capable of controlling a digital X-ray detector, an X-ray image obtained by the digital X-ray detector is acquired and display control of the system control unit 2 is performed. X-ray image data is displayed on the second monitor 10 in accordance with the control of the unit.

  The X-ray generation unit includes an X-ray tube 6 including, for example, an electron source, a high-voltage application unit that accelerates electrons generated by the electron source, and a target that generates X-rays when the accelerated electrons collide. Have. The collimator 8 shapes the generated X-ray so as to have a desired beam bundle shape. When an irradiation switch (not shown) of the X-ray imaging apparatus is pressed by the user, the X-ray generation unit irradiates X-rays with respect to a predetermined condition and range.

  In FIG. 1, the movable carriage 1 is a carriage section that holds the column section 3 that supports the X-ray generation section 6 so as to be rotatable in the axial direction, and is movable by a front wheel 12 and a drive wheel 13. The front wheel 12 supports moving power and weight. The drive wheel 13 has an axle that rotates in response to an operation. Here, the drive wheel 13 may employ a configuration in which a rotational force from an electric drive mechanism such as a motor is received by the axle to rotate. A battery is mounted in the mobile carriage 1 and can be charged as necessary. In addition, when moving or when no power is supplied from an external power source, power is supplied from the battery to each part in the X-ray imaging apparatus. Is supplied.

  The column part 3 extends in the vertical direction, and holds the arm 5 extending in the horizontal direction from the side surface via the column movable part 4. Moreover, the support | pillar movable part 4 is hold | maintained at the support | pillar part 3 so that raising / lowering is possible with respect to the perpendicular direction. As a result, the arm 5 translates in the vertical direction, so that the X-ray generator held by the arm 5 can be moved up and down. Moreover, the structure which raises / lowers the arm 5 with respect to the support | pillar movable part 4 is also employable. Thereby, a large range of movement in the vertical direction can be secured. In the example shown in FIG. 1, the movable support column 4 is in a state where it is arranged at the lowest position with respect to the support column part 3. When the X-ray imaging apparatus is moved, forward visibility can be ensured by setting the support column in the most contracted state. In addition, since the position of the center of gravity of the entire apparatus can be lowered, there is an advantage that safe movement is easily realized.

  Further, as described above, the support column 3 can rotate with respect to the carriage unit 1 around the axis of the support column 3, so that the X-ray generation unit indirectly held by the support column 3 is turned by the rotation of the support column 3. It becomes possible.

  One end of the arm 5 is held by the column movable part 4 and the other end by the X-ray generation part. Here, the arm 5 employs, for example, a telescopic type or a pantograph type expansion / contraction mechanism, and can move the X-ray generation unit in a direction away from the support column. In the example shown in FIG. 1, the arm 5 is a telescopic type as an expansion / contraction mechanism, and a plurality of moving arm members are configured to be movable relative to each other. The state shown in FIG. 1 is a state in which the plurality of partial arm members are moved to the most support column side and are substantially housed in the holding arm member held with respect to the movable arm.

  A monitor 17 is provided on the side surface of the collimator 8 and is held in a state where the display surface of the monitor 17 faces the horizontal direction. The monitor 17 is provided in accordance with the size of the collimator 8. For example, the monitor 17 has a display surface smaller than one side surface of the collimator 8, and is sized and shaped so that the outer frame of the monitor 17 does not protrude from the side surface of the collimator 8. And Further, for example, by setting the monitor 17 to be smaller than the second monitor 10, the X-ray generation unit can be easily handled. Of course, the monitor 17 may be held not on the collimator 8 but on the side surface of the housing of the X-ray tube. In this case, when the X-ray tube 4 is arranged and moved at a low position as shown in the figure, the monitor 17 is arranged at a higher position than that held by the collimator 8. Can be made easier to see.

  Here, the monitor 17 is held in the X-ray generator by the movable mechanism so that the orientation of the display surface can be changed. The movable mechanism is, for example, a hinge, one surface of which is held by the collimator 8 and the other surface is held by the housing on the back side of the monitor 17. Since the hinge has a structure in which two metal plates rotate around a central axis, the two metal plates are respectively held by the monitor 17 and the X-ray generation unit, thereby monitoring the X-ray generation unit. The direction of the 17 display surfaces can be changed.

  In one embodiment, the hinge connects the monitor 17 and the collimator 8 so that the display surface of the monitor 17 is horizontal and has an angle of attack on the upper side with respect to the horizontal direction. In the example of FIG. 1, a state in which the angle of attack on the upper side with respect to the horizontal direction is set so that the display surface of the monitor 17 faces upward is shown. According to such an example, for example, when irradiating the X-ray generation unit from the bottom to the top of the subject, or when the X-ray generation unit is arranged at a position close to the floor on which the X-ray imaging apparatus is placed Or, when the X-ray generation unit is lowered to some extent during movement as in the example shown in FIG. 1, the display surface faces the operator side when the operator looks down at the monitor 17. As a result, visibility is improved. From the viewpoint of forward visibility and the like described above, it is desirable that the movable support column 4 be lower than the support column 3 and the arm 5 be positioned lower than the support column. Combined with the fact that the display surface of the monitor 17 held in the unit can be directed upward, both forward visibility and visibility of the monitor can be achieved.

  In another example, the hinge connects the monitor 17 and the collimator so that the display surface of the monitor 17 has a horizontal angle of attack and a lower angle of attack with respect to the horizontal direction. For example, one of the metal plates is coupled to the side surface of the collimator 8 and the other is connected to the back surface of the monitor 17 so that the rotating shaft portion is located below the two metal plates with the two metal plates of the hinge closed. Join. As a result, the orientation of the display surface is changed so that the angle of attack of the monitor 17 increases downward with respect to the horizontal direction by turning the metal plate with respect to the rotation axis. Thereby, for example, when the tube portion is arranged above the subject at the time of photographing, if the angle of attack of the monitor 17 is set, the monitor 17 is more subject than the case where the angle of attack is not set. The visibility during shooting is improved.

  The display surface of the monitor 17 only needs to be able to change the angle of attack about ± 15 degrees with respect to the horizontal direction. For example, if the hinge of the movable mechanism is appropriately selected and can be changed ± 45 degrees, it can handle more situations. And visibility can be secured. In the example shown in FIG. 1, the upward angle of attack can be changed to about 60 degrees. When the entire X-ray imaging apparatus is moved in the arrangement relationship as shown in FIG. 1, it can be confirmed simply by moving the line of sight to the monitor 17 side, which is useful.

  In each of the above-described examples, an operation unit that receives an operation input, such as buttons and knobs provided around the monitor 17 and operable by an operator, and a touch panel provided integrally with the monitor 17 may be provided. it can. Here, if these operation units are also held by a hinge so as to be changeable, the operability of these operation units can be improved in addition to the visibility.

  In addition to the X-ray generation conditions by the X-ray generator, the monitor 17 displays X-ray image data obtained by detecting the X-rays generated by the X-ray imaging apparatus with a digital X-ray detection unit or a reduced image thereof. be able to. Thereby, for example, when it is necessary to continuously perform a plurality of imaging, the captured X-ray image is displayed on the monitor 17 of the X-ray generation unit, thereby quickly confirming the presence or absence of imaging problems. In addition to moving to the next shooting, if there is a problem, it is possible to move immediately to another shooting.

  The system control unit 2 is a control unit that integrally controls the operation of the mobile X-ray imaging apparatus, and performs X-ray generation by the X-ray generation unit 6 and display control of the monitor 17.

  An X-ray high voltage generator, an X-ray control device, and an X-ray having a control panel and a system control unit 2 are mounted. The X-ray and system control unit 2 also has a holding function when the arm 7 is moved.

  In the example shown in FIG. 1, when the operator 21 moves, the display surface of the monitor 17 of the X-ray generation unit faces upward, and the monitor 17 can be used to make various settings such as starting up the power and preparing for imaging. Here, the monitor 17 preferably includes a touch panel type operation unit. Here, in the preparation for shooting, one of a plurality of shootings included in the selected shooting order, an instruction to start receiving a shooting order from the RIS (Radiology Information System), an instruction to sequentially select the received shooting orders, and the like. There are an instruction to select, an imaging region related to the selected imaging, an imaging condition of the digital X-ray detector, an instruction to confirm and change the X-ray generation condition, an instruction to start imaging, and the like. The system control unit 2 controls at least one of the wireless communication unit and the wired communication unit in response to an order reception start instruction, and receives imaging order information from the RIS. In response to the instruction to select the imaging order, the display control unit of the system control unit 2 displays information on the subject corresponding to the selected imaging order on the monitor 17 and at least one imaging method included in the imaging order. Are displayed side by side. In response to an instruction to change the imaging region, imaging conditions, and X-ray generation conditions, the system control unit 2 notifies the digital X-ray detector and the X-ray generation unit of the change of the conditions. In response to the imaging start instruction, the system control unit 2 instructs the X-ray generation unit to generate X-rays, acquires digital X-ray image data obtained by the generation from the digital X-ray detector, and displays the control unit. Is displayed on the monitor 17.

  In addition, in the example shown in FIG. 1, the X-ray generation unit is stored in a storage unit 103 formed integrally with the movable carriage 1 when moving. The storage unit 103 includes a bottom surface part and a wall surface part 102 along at least one side surface of the X-ray generation part. A cutout corresponding to the arm 5 is provided on the side surface of the storage unit 103 on the support column side, and the X-ray generation unit can be stored in the storage unit 103. As a result, when the X-ray generation unit is stored such as when it is moved, the possibility of receiving an impact by buffering with the external structure can be reduced. An imaging unit storage unit 101 is provided below the storage unit 103 to store the imaging unit when moving.

  An example of an embodiment in which the monitor 17 can be tilted and the display surface can be directed both upward and downward will be described with reference to FIG. In this example, the movable mechanism of the monitor 17 is composed of a plurality of movable parts, and the display part can be rotated around a plurality of axes.

  In the example shown in FIG. 2, the side surface of the collimator 8 and a hinge connecting member 32 made of, for example, a metal plate are movably held by the first hinge 31. Further, the second hinge 33 holds the hinge connecting member 32 and the monitor 17 movably. Thereby, the monitor 17 is held by the collimator 8 via the first hinge 31, the hinge connecting member 32, and the second hinge 33. In order to make it upward, the second hinge 33 is rotated and moved to an arbitrary position by pulling up the lower side of the monitor 17.

  The second hinge 33 incorporates a friction holding mechanism (not shown) that keeps the rotational operation torque constant so that the position can be maintained even if the touch operation device built in the monitor 17 is operated. This improves the operability of the touch panel.

  In order to make the display surface of the monitor 17 face down, the first hinge 31 can be rotated and moved to an arbitrary position by pulling down the monitor 17 as shown in FIG. The first hinge 31 incorporates a friction holding mechanism (not shown) that keeps the rotational operation torque constant even if the touch operation device built in the weight and the monitor 17 is operated, so that the position can be held. . Here, by moving the monitor 17 around the second hinge in the state shown in FIG. 3, it is possible to change the orientation of the monitor 17 while moving the monitor 17 away from the X-ray tube.

  In the above-described example, the embodiment in the case where the angle of attack with respect to the horizontal direction is changed has been described. However, the present invention is not limited to this, and other movable mechanisms may be provided to arbitrarily change the direction of the monitor 17. In this case, a movable mechanism is provided that holds the monitor 17 in a rotatable manner while maintaining the orientation of the display surface.

  For example, when the irradiation direction can be changed, such as when the X-ray generator rotates about the axis of the arm, or when the X-ray generator tilts, the upper and lower sides of the display unit held by the X-ray generator There are cases where the direction does not align with the vertical direction. Corresponding to such a case, it is possible to provide a rotation mechanism for connecting the monitor 17 to one side surface of the X-ray generation unit and coupling the monitor 17 so as to be rotatable along the one side surface. Thereby, the monitor 17 can be rotated with respect to the X-ray generation part, and visibility can be improved by rotating according to the situation.

  Alternatively, the same effect can be obtained when the display control unit rotates the display content of the display unit in response to an operation input from the operation unit provided in the X-ray generation unit or the carriage unit 1. Further, a sensor for detecting the rotation state of the X-ray generation unit may be provided, and the display control unit of the system control unit 2 may rotate and display information to be displayed on the display unit according to the output from the sensor. Good. For example, in this case, when the X-ray generation unit is rotated +10 degrees in the axial direction by the output from the sensor, the display content is displayed by rotating the display content by −10 degrees so as to cancel the rotation. By doing in this way, it is possible to display the display content in an orientation that is easy for the operator to view without requiring the operator's operation.

  In addition, in the example shown in FIG. 3, the collimator 8 is provided with a collimator handle 9. The handle 9 is integrally formed with a first portion extending in a direction along the injection direction of the collimator 8 and a second portion curved in a direction perpendicular to the injection direction below the collimator emission surface. ing. The second portion of the handle 9 can be provided with a function as a stopper that comes into contact with the side surface of the storage portion during storage. In this case, for example, a shock-absorbing member such as rubber is provided on the lower side of the second part or on the front side when viewed from the injection direction, so that the impact at the time of contact can be reduced.

  FIG. 4 is a perspective view of an embodiment of a mobile X-ray imaging apparatus according to the present invention. In the example shown in FIG. 4, a second monitor 10 (second display unit) larger than the monitor 17 (first display unit) is provided on the carriage 1 below the housed X-ray generation unit. The second monitor 10 is provided on the bottom surface side of the storage unit 103 and is held at a position where it can be seen by detaching the X-ray generation unit from the storage position. Here, the second monitor 10 is installed on the movable carriage 1 and is held by a pair of guide rails that are slidably held in a direction along the straight traveling direction of the mobile X-ray imaging apparatus toward the operator. It can be configured as follows. By doing so, even when the X-ray imaging apparatus is moving, the operator can confirm the monitor information by sliding the second monitor 10. Note that, for the second monitor 10 as well, if a movable mechanism capable of changing the orientation of the display surface is provided in the same manner as the monitor 17, the visibility by the operator can be further improved.

  Similarly to the monitor 17, the second monitor 10 is controlled by the display control unit of the system control unit 2. The display control unit can perform control to turn off one monitor and turn on the other monitor when moving or storing. Since the two monitors are close to each other during movement or storage, it is sufficient to activate only one of them and display the information. For example, if a sensor for detecting contact with the handle 9 of the X-ray generation unit is provided at a specific position on the side surface of the storage unit 103 and the system control unit 2 detects a signal indicating contact, the X-ray generation unit Is detected, and in response to this, control is performed to turn off one of the power supplies. For example, when moving, it is only necessary to know information such as subject information scheduled for imaging, and when it is not necessary to display so much information, the display control unit turns on the smaller monitor 17 and turns it on. Control to turn off the power of the monitor 10 is performed. This is also useful from the viewpoint of power consumption. Alternatively, when there is a lot of information to be displayed such as detailed information of the subject, communication with the RIS, and changing the setting of the imaging conditions even when moving, the display control unit turns off the smaller monitor 17 and turns off the monitor. Control to turn on the power of 10 is performed. Alternatively, the display area can be effectively utilized by turning on both monitors and displaying different information. Moreover, it is good also as the system control part 2 switching which control is employ | adopted based on setting information. In addition, it is convenient that the display control unit does not perform the above control when the storage of the X-ray generation unit is detected in a state where the power of any monitor is OFF.

  In addition, even if there is a monitor in which the power is turned on at the time of storage, the display control unit may not be used. Therefore, when the X-ray generation unit is stored in the storage unit, the display control unit Power consumption can be reduced by stopping the display unit to stop power supply and performing control to maintain power supply to the first display unit for at least a certain period.

  On the other hand, when the X-ray generation unit is detached from the storage position, such as during imaging, the positions of the monitor 17 and the second monitor 10 are different. Control. For example, before imaging, the X-ray generation conditions may be changed as appropriate by looking at the condition of the subject. In addition, it is important to confirm whether or not the captured image has been properly performed by looking at the X-ray image after imaging. Since such information is highly likely to be used in each scene, it is assumed that it is displayed on each monitor in duplicate in each situation. Regarding the determination of the situation before and after imaging, for example, it is determined that the period from when the subject to be imaged is selected until the irradiation switch is pressed is before imaging, and the next subject after the irradiation switch is pressed Alternatively, it is realized by the system control unit 2 determining after imaging until the next imaging site is selected. As a result, information that is highly likely to be used can be confirmed on any of the monitors, so that the work efficiency of the operator can be improved.

  Next, FIG. 5 shows a form at the time of photographing. When approaching the subject, which is the photographing location, first, the moving handle 11 is first lifted upward, and it is attempted to move toward the subject as it is. Then, the first support column 3 and the second support column 4 having a balance function can be easily lifted and turned. The X-ray tube support arm 5 is also extended so that the X-ray tube 6 can be easily arranged on the subject. If the angle of the monitor 17 is moved downward at this position, the visibility is improved. The X-ray tube 6 is adjusted to the imaging position, and imaging conditions are input from the monitor 17. The shooting conditions can also be input from the second monitor 10 on the mobile carriage 1 with a built-in power supply. This completes the series of shooting preparations.

  Next, X-ray imaging is performed in the same manner as a general X-ray imaging apparatus. X-rays are irradiated from the X-ray tube 6 by pressing an irradiation switch (not shown) and shaped by the lower collimator 8. The line passes through the body of the subject and an image is captured on the flat panel for imaging. The captured image is transmitted to the system control unit 2 by X-rays by wireless or wired (not shown), and the image is confirmed on the second monitor 10 or the monitor 17 to end.

  Another embodiment will be described with reference to FIG. Here, a method is employed in which the monitor 17 is driven electrically and the work of manually adjusting the angle is simplified. Therefore, in order to change the orientation of the display surface of the monitor 17, an electric mechanism such as an actuator that electrically operates the movable mechanism is provided, and an electric control unit that controls the electric mechanism is incorporated in the system control unit 2.

  First, the collimator 8 is connected to the holding side of the first hinge 34 with an actuator, and the movable side can be moved to an arbitrary angle by driving the actuator. A hinge connecting member 32 is connected to the movable side, and the holding side of the second hinge with actuator 35 is connected to the end on the extended side, so that the movable side can be moved to any angle by driving the actuator. A monitor 17 is connected to the movable side and can be set at an arbitrary position from 90 ° upward to 90 ° downward.

  In addition, the height information of the arm 5 is set so that it can be output in advance to the X-ray system controller 2, and the drive of the first hinge 34 with the actuator and the second hinge 35 with the actuator are linked based on this information. By simply adjusting the position of the X-ray tube 6, the monitor 17 is automatically adjusted to an angle that is easy to visually recognize.

  The height information of the arm 5 is obtained when the system control unit 2 obtains outputs from the sensor that detects the stretched state and the sensor that detects the lifted state of the arm with respect to the column when the column expands and contracts. Is calculated. Thereby, the height of the X-ray generation unit, that is, the monitor 17 can be specified.

  For example, when the height of the arm 5 is lower than the threshold, the electric control unit controls the actuator so that the display surface of the monitor 17 faces upward. When the height of the arm 5 is higher than the threshold, the monitor 17 The actuator is controlled so that the display surface of the screen faces downward. For example, when the height of the X-ray generation unit is higher than 1.7 m, the electric control unit tilts the angle of attack of the monitor 17 downward by 10 degrees to 30 degrees with respect to the horizontal direction, and from 1.8 m If it becomes too high, tilt it about 60 degrees. Thereby, the orientation of the display surface of the monitor can be controlled according to the position of the monitor 17. Instead of this, or in addition to this, when the height of the X-ray generation unit is lower than 1 m, the angle of attack of the monitor 17 is tilted upward by 10 degrees to 30 degrees with respect to the horizontal direction, and 0.8 m If the angle is lower than that, control for tilting the angle of attack of the monitor 17 by about 60 degrees is executed. Alternatively, the electric control unit adopts a control that gradually increases the upper angle of attack when it becomes higher than the predetermined height position, and gradually decreases the lower angle of attack as it decreases. can do.

  Furthermore, height information of the operator 21 and the like can be registered in advance in the X-ray and the system control unit 2, and can be automatically adjusted to an optimum angle from the height information and the height information of the X-ray generation unit. For example, a table for specifying the line-of-sight height from standard human information based on the height information is stored in the memory, and the system control unit 2 calculates the line-of-sight height according to the height information. In addition, the predetermined height position referred to in the above example is specified from the height of the line of sight. Thereby, the height of the direction of the monitor 17 can be adjusted according to the operator.

  In addition, what combined the above-mentioned embodiment suitably is also contained in embodiment of this invention. Alternatively, a case where the above-described processing is realized by cooperation of a program and hardware is also included in the embodiment of the present invention. In the embodiment by the program, it is achieved by storing the program corresponding to the above-described processing, the program in the storage unit, the CPU of the system control unit expanding in the RAM, and executing the command included in the program by the CPU. Is done.
