  As described above, in the conventional X-ray imaging apparatus, there are a standing type in which an image is taken while the subject is standing and a vertical type in which an image is taken while the subject is laid on an imaging table. It is preferable to provide both a standing type and a standing type X-ray imaging apparatus. That is, in the conventional standing X-ray imaging apparatus, since the image receiving unit is often suitable for chest imaging and is relatively small, it is often impossible to perform whole body imaging. In addition to the X-ray apparatus, it is preferable to provide a recumbent X-ray apparatus.

  However, depending on the size of the X-ray room in which the X-ray imaging apparatus is installed, there may be a case where neither the standing type or the standing type can be arranged. In particular, in the standing X-ray imaging apparatus, the X-ray irradiator is arranged on the rear side of the X-ray imaging apparatus, whereas in the standing X-ray imaging apparatus, the X-ray irradiator is arranged above the imaging table. Therefore, the X-ray irradiator cannot be used with the standing X-ray imaging device and the vertical X-ray imaging device, and a large space is required for this purpose. In addition, it is possible to point out a problem that it is impossible to arrange both the standing type and the standing type, and it is costly to place both the standing type and the standing type.

  Thus, the present invention provides an imaging apparatus that can reduce the cost without taking up space in the X-ray room by enabling both standing-up type imaging and lying-down type imaging. It is said.

Detector) and amorphous selenium or the like for the sensor, and a so-called direct conversion type FPD that directly converts X-rays into electrical signals.

  Further, the cassette and the image sensor incorporated here are not limited to one, and a plurality of cassettes and image sensors can be used side by side. In this way, by using a plurality of sheets, it is possible to reduce the cost as compared with the case of creating a large area cassette or an image sensor.

  Furthermore, as described above, in the X-ray imaging apparatus of the present embodiment, the light receiving unit 8 having a built-in light receiver can be inserted and removed freely. However, the light receiving unit 8 is not an essential component of the present invention. The photographing table 6 may be supported by the drive unit 5.

  The photographing table 6 has a rectangular shape, is rotatable along the front surface of the main body 2, and is supported by the drive unit with a vertical angle adjustable. That is, the photographing table 6 has a pivot function and a tilt function. Moreover, when it rotates along the front of the said main-body part 2, it can fix in arbitrary positions.

  Therefore, in the imaging table 6 in the X-ray imaging apparatus 1 of the present embodiment, when performing standing X-ray imaging, the imaging table 6 is moved up and down to increase the height according to the height of the subject. The height of the subject can be adjusted, and the whole body of the subject can be photographed. Further, when photographing the whole body of the side of the subject, the state can be accommodated even if the subject's waist is bent, etc., by rotating the photographing table 6 to an arbitrary angle.

  Further, the photographing table 6 is rotated sideways so that the longitudinal direction is directed to the left and right sides, and is lowered, and the vertical angle of the photographing table 6 is further rotated by 90 degrees so that the photographing table 6 faces upward. It is also possible to shoot in a supine position. FIG. 1 is a diagram showing a state in which the photographing for standing position is performed, and FIG. 2 is a diagram showing a state in which the photographing table 6 is unfolded for standing. The photographing table is not necessarily long and may be square. As shown in FIGS. 1, 2, and 3, in this embodiment, the operation switch group is provided on the upper side surface of the support column, but the arrangement position of the switch group is not particularly limited.

  Next, the raising and lowering method of the drive unit 5 will be described. FIGS. 6 and 7 are diagrams for explaining the drive unit 5, in which 4 is a part of the column 4 in the main body 2. Show. In FIG. 2, reference numeral 5 denotes a drive unit. In this embodiment, the drive unit 5 is supported by the main body unit 2 by a ball screw so as to be movable up and down.

  That is, in FIGS. 6 and 7, a screw shaft 9 of a ball screw is mounted in the support column 4 in the vertical direction. The drive unit 5 is provided with a ball screw nut (not shown) that moves up and down along the screw shaft 9 by rotating the screw shaft 9. The drive unit 5 can be raised and lowered by the rotation of the shaft 9. In the figure, reference numeral 10 denotes a lifting motor for rotating the screw shaft 9. However, in the present invention, the raising / lowering method of the drive unit 5 is not particularly limited, and it is not necessarily required to be able to be raised and lowered by a ball screw. Therefore, for example, the drive unit may be made movable up and down using a counter balance mechanism using a counter weight or a balance mechanism using a balancer device such as a spring balancer, or the drive unit is supported by a chain or a wire. The drive unit may be freely raised and lowered by moving the chain and wire up and down using a motor (see Japanese Patent Application Laid-Open No. 2014-124396).

  Next, the configuration of the drive unit 5 will be described with reference to FIGS. 6 and 7. In the present embodiment, the drive unit 5 has a pair of first arms 11. It can be rotated in the vertical angle direction. That is, in the present embodiment, the drive unit 5 has an arm turning motor 12. On the other hand, a worm gear is housed in the gear box 13, and the worm wheel of the worm gear is placed in the gear box 13. A one-arm rotation shaft is connected, and the first arm 11 is connected to the first arm rotation shaft.

  The arm turning motor 12 and the worm gear are connected to each other by a pulley and a belt 15. By driving the arm turning motor 12, the worm of the worm gear is rotated via the pulley and the belt 15. The first arm rotating shaft is rotated via a wheel so that the first arm 11 is freely rotatable in the vertical angle direction.

  Next, a second arm rotating shaft 16 is rotatably disposed between the pair of first arms 11, and the second arm rotating shaft 16 is rotated by the second arm rotating shaft 16. A rotating pulley 17 that rotates together with the rotation pulley 17 is fixed.

  A pair of second arms 18 are connected to both end sides of the second arm rotating shaft 16, and the second arm 18 rotates with the rotation of the second arm rotating shaft 16. .

  Further, a substantially disc-shaped turning table 19 is connected to the distal end portion of the second arm 18. The swivel table 19 is rotatable, and the photographing table 6 is detachably mounted on the upper surface of the swivel table 19, so that the photographing table 6 can be mounted. The table 6 is rotatable along the front surface of the main body 2. The turning table 19 does not necessarily have a substantially disk shape, and may have any shape as long as the photographing table 6 can be detachably attached to the upper surface.

  On the other hand, a fixed pulley 20 is fixed to the drive unit 5 so as not to be rotatable, and a second arm turning belt 21 is wound between the fixed pulley 20 and the rotating pulley 17. Thus, by driving the arm turning motor 12 and rotating the first arm 11, the vertical angle of the photographing table 6 can be adjusted and the vertical angle of the photographing table 6 is fixed at 90 degrees. It is possible to do.

  That is, the distal end side of the first arm 11 is directed upward, the distal end side of the second arm is directed downward, and the imaging table 6 is directed to the front side so that standing-type imaging is possible. When the first arm 11 is rotated in the direction in which the tip end descends, the fixed pulley 20 is fixed to the drive unit 5 and the second arm swivel belt 21 does not move in the longitudinal direction. The second arm 18 moves so as to roll in the second arm revolving belt 21 while rotating so as to rotate in the opposite direction to the first arm 11. Then, the distal end side of the second arm 18 is rotated upward, whereby the upper surface of the turning table 19 is directed upward, the photographing table 6 is directed upward, and the saddle-type photographing can be performed. Therefore, in the X-ray imaging apparatus 1 of the present embodiment, it is possible to easily switch between the imaging in the standing position and the imaging in the lying position.

  However, the drive unit in the present invention is not necessarily configured in this way, and the configuration of the drive unit is particularly limited as long as the imaging table supported by the drive unit is rotatable and the vertical angle is adjustable. Not.

  Further, even when the above-described configuration is adopted, that is, a pair of first arms 11 that are rotatable in the vertical angle direction, and a second arm that is rotatably disposed between the pair of first arms 11. A rotating shaft 16, a rotating pulley 17 fixed to the second arm rotating shaft 16, and rotating with the rotation of the second arm rotating shaft 16, and a pair of second arms fixed to both ends of the second arm rotating shaft 16 Even when a driving unit having a turning table 19 connected to the tip portions of the 18 and the second arms 18 is employed, the first arm 11 is necessarily rotated using the arm turning motor 12. Instead, the first arm 11 may be manually rotated.

  Although the method for making the turning table 19 rotatable and thereby making the photographing table 6 rotatable is not particularly limited, in this embodiment, although not shown, the tip of the second arm 18 is omitted. A plate is attached to the plate, a turning bearing is attached to the plate, the turning table 19 is attached to the turning bearing, and the photographing table 6 is attached to the turning table 19, thereby making the photographing table 6 rotatable. ing. In this embodiment, a ring gear is attached to the turning table 19, and a small gear incorporating an electromagnetic brake is engaged with the ring gear. Then, with the operation button pressed and the electromagnetic brake released, the imaging table 6 is manually rotated, and when the desired angle is reached, the electromagnetic brake is activated by releasing the operation button. Thus, the photographing table 6 can be fixed at an arbitrary angular position.

  Next, FIG. 4 is a view showing the main body 2 from the bottom, and in the figure, 22 is a moving wheel. That is, in the X-ray imaging apparatus 1 of the present embodiment, a pair of moving wheels 22 are provided at the bottom of the main body 2 so that the X-ray imaging apparatus 1 can be moved to a desired position. That is, in the case of X-ray imaging in a standing position, X-ray imaging is performed to irradiate X-rays from behind the subject, while in the case of X-ray imaging in supine position, X-ray imaging is performed from above the subject. When the position of the apparatus is fixed, the subject may not be able to accurately irradiate the subject with X-rays. However, since the X-ray imaging apparatus of the present embodiment includes the moving wheel 22 and can move to a desired position, the X-ray imaging apparatus can move to a position where X-rays can be accurately irradiated to the subject. it can.

  Next, in FIGS. 1 to 3, reference numeral 23 denotes a dock, and FIG. 5 is a perspective view showing the dock 23. That is, in the present embodiment, the main body 2 includes a dock 23. As shown in FIG. 5, the dock 23 has an engagement protrusion 24. On the other hand, an engagement groove (not shown) with which the engagement protrusion 24 is engaged is formed on the back surface portion of the main body 2. The main body 2 can be fixed to the dock 23 by engaging the engaging protrusion 24 with the engaging groove.

  Therefore, by fixing the dock 23 to the floor or the like, even when the X-ray imaging apparatus 1 of the present embodiment is moved to a desired position, it can be returned to a fixed position. In addition, it is not necessary to adjust the distance to the X-ray irradiator. That is, as described above, in the case of X-ray imaging in the standing position, X-rays are irradiated from behind the subject, while in the case of X-ray imaging in the supine position, X-rays are irradiated from above the subject. In addition, in the X-ray printing apparatus of the present embodiment, when taking an image in a supine position after taking an image in a standing position, or conversely, when taking an image in a standing position after taking an image in a lying position, Each time, it is necessary to adjust the position of the apparatus so that the subject is surely irradiated with X-rays. However, for example, the position of the apparatus in a state where the main body 2 is fixed to the dock 23 is set as a fixed position for performing imaging by standing, and in the case of imaging by lying down, the imaging table 6 is irradiated with X-rays. When the apparatus is moved to a position located below the machine, the apparatus is moved and photographing is performed in a lying position, and then the apparatus is moved to fix the main body 2 to the dock 23 and return to the home position. Thus, it is possible to perform photographing by standing without changing the position. Therefore, in the X-ray imaging apparatus of this embodiment, preparation for imaging is easy. 1 to 4, reference numeral 25 denotes a moving grip used when the X-ray imaging apparatus 1 of the present embodiment is moved to a desired position. This grip 25 is usually directed downward. When used, as shown in FIG. 3, it is used by rotating to the front side.

  Next, the operation of the X-ray imaging apparatus 1 of the present embodiment configured as described above will be described. When performing X-ray imaging of a subject with the X-ray imaging apparatus of the present embodiment, first, as preparation for imaging, One or a plurality of cassettes for receiving a photographic film that is exposed to X-rays, or one or a plurality of photoreceptors such as an image pickup element are built in the light receiving unit 8, and the light receiving unit 8 is stored in the imaging table 6. When X-ray imaging is performed in a standing position, as shown in FIG. 1, the upper surface of the imaging table 6 is adjusted to the body shape of the subject with the upper surface of the imaging table 6 facing the front side. Further, when photographing the subject's side, when the photographing table 6 is set in the vertical direction because the subject's waist is bent, the photographing table 6 can be arbitrarily set. Rotate to an angle. Then, with the subject standing on the front of the imaging table 6, X-rays are irradiated toward the subject from behind. If it does so, the irradiated X-ray permeate | transmits a test subject, and it becomes possible to visualize a test subject's body on a film for imaging, an image pick-up element, etc. now. In this state, the first arm 11 has the tip side facing upward, and the second arm 18 has the tip side facing downward.

  Next, when photographing the subject's recumbency in this state, the photographing table 6 is turned 90 degrees and turned sideways, and the drive unit 5 is lowered. Further, as described above, the arm turning motor 12 is driven so that the distal end side of the first arm 11 is rotated in a descending direction.

  Then, as described above, the second arm 18 moves while rotating so as to roll in the second arm revolving belt 21, and the tip end side of the second arm 18 is moved upward. To turn. As a result, the upper surface of the turning table 19 is directed upward, and the imaging table 6 is directed upward as shown in FIG. Then, by irradiating the subject with X-rays from above with the subject lying on the photographing table 6, the subject's body can be visualized on a photographing film, an image sensor, or the like. In this state, the front end of the first arm 11 faces obliquely downward, and the second arm 18 is in a horizontal state. In this state, by rotating the arm turning motor 12 in the opposite direction, the front end side of the first arm 11 is directed upward and the front end side of the second arm 18 is directed downward. As shown in FIG. 1, the imaging table 6 can be directed to the front side to enable imaging of the subject standing.

  As described above, the X-ray imaging apparatus according to the present embodiment can perform both the standing X-ray imaging and the supine X-ray imaging without taking up the space of the X-ray room and suppressing the cost. At this time, as described above, it is possible to easily switch between the shooting in the standing position and the shooting in the lying position.

  In addition, since the X-ray imaging apparatus of the present embodiment includes a moving wheel and can be moved to an arbitrary position and includes a dock, the X-ray can be obtained even when moving to a desired position. The photographing apparatus can be returned to a fixed position, and preparation for photographing is easy.

  Furthermore, in the X-ray imaging apparatus of this embodiment, since the imaging table 6 is detachable, it is possible to bring only the imaging table to a desired place and use it as a free table.

  The present invention can be applied to all X-ray imaging that may perform X-ray imaging of a subject in a standing position and a lying position.
