Description

Description: FIELD OF THE INVENTION The present invention relates to an X-ray imaging apparatus, and in particular, is used as an X-ray imaging apparatus for examining the health of an animal such as a racehorse.

2. Description of the Related Art Conventionally, as an X-ray imaging apparatus of this type, an X-ray tube and an X-ray processing unit for receiving a X-ray emitted from the X-ray tube and exposing a film to the X-ray tube are respectively suspended from a ceiling. There has been proposed one that is arranged and configured to be movable in a horizontal plane and vertically. Then, the X-ray tube and the X-ray processing unit are arranged at appropriate positions in the vicinity of the object to be inspected, such as a racehorse, to perform X-ray photography, thereby inspecting the health condition of the racehorse, etc.

(Problems to be Solved by the Invention) However, since a racehorse or the like as an object to be inspected is large and X-rays may be radiated obliquely to the object to be inspected, unlike a conventional X-ray imaging apparatus, With a single X-ray tube, it was difficult to image the entire inspection object, and a sufficient inspection could not be performed.

(Means for Solving the Problems) The X-ray imaging apparatus according to the present invention is configured such that a first X-ray tube suspended from a ceiling is configured to be movable in a horizontal plane and vertically movable, The first X-ray tube is configured to be rotatable in the horizontal and vertical directions, while the second X-ray tube is configured to be movable in a horizontal plane on the floor, and to be rotatable in the horizontal and vertical directions. And an X-ray processing unit that receives X-rays emitted from the second X-ray tube is suspended from the ceiling and is configured to be movable in a horizontal plane and vertically.

(Operation) The first X-ray tube is arranged at an appropriate position near an object to be inspected such as a racehorse, and an X-ray processing unit is arranged so as to correspond to the first X-ray tube to perform X-ray imaging. Further, the second X-ray tube is arranged at an appropriate position on the floor surface, and the X-ray tube is set to correspond to the second X-ray tube.
An X-ray imaging is performed by arranging a line processing unit. This second X-ray tube
X-ray imaging is performed on an inspection location that cannot be dealt with by an X-ray tube or an inspection location that is better suited for imaging by a second X-ray tube.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

 FIG. 1 shows an X-ray imaging apparatus according to the present invention.

The X-ray imaging apparatus includes a first unit A provided on the ceiling and having a first X-ray tube 11, and an X-ray processing unit 31 also provided on the ceiling.
And a second X-ray tube disposed on the floor
And a second unit B having 21.

The first unit A is provided with a pair of guide rails 12 laid in an appropriate direction on the ceiling, and is disposed below the guide rails 12 in a direction orthogonal to the guide rails 12 and moves along the guide rails 12. A freely movable guide rail 13, a carriage 15 movably arranged along the guide rail 13, and a carriage
A boom 16 that is provided at the bottom of 15 and that can expand and contract vertically
The first X-ray tube 11 is provided at the tip of the boom 16.

The guide rail 12 is laid in the entire length direction of the inspection object (racehorse or the like) arranged at the inspection position. Hereinafter, in this example, this direction is referred to as an X-ray direction, and is laid in the X-ray direction. The guide rail 12 is called an X-ray guide rail 12. In addition, disposed in a direction orthogonal to the guide rail 12,
In other words, the inspection target is a guide rail 13 arranged in the width direction of the object.
Is referred to as a Y-axis direction, and this guide rail 13 is referred to as a Y-axis guide rail 13. Note that these X-axis guide rails 12
The direction in which the Y-axis guide rails 13 are laid may be appropriately determined in consideration of the space in the inspection room.

The Y-axis guide rail 13 is movable along the X-axis guide rail 12 by an appropriate moving device including a motor and the like. The carriage 15 can run along the Y-axis guide rail 13 by an appropriate traveling device equipped with a motor and the like.

For example, a conventionally known multi-stage boom is used as the boom 16, and the boom 16 can be extended and contracted by an appropriate driving device including a winch, a wire, and the like. A holding section 17 is provided at the tip of the boom 16, and the first X-ray tube is attached to the holding section 17.
11 are rotatably held in the horizontal and vertical directions. The first X-ray tube 11 is for irradiating an X-ray to the object to be inspected, and is configured to be three-dimensionally movable by movement of the Y-axis guide rail 13 and the carriage 15 and expansion and contraction of the boom 16. .

The second unit B includes a pair of X-axis guide rails 22 laid in the X-axis direction in a recess formed in a part of the floor.
A Y-axis guide rail 23 disposed above the X-axis guide rail 22 in a direction orthogonal to the Y-axis guide rail 22 (Y-axis direction) and movable along the X-axis guide rail 22;
A truck movably arranged along the Y-axis guide rail 23
25, and a second X-ray tube 21 provided on the upper surface of the cart 25.

The Y-axis guide rail 23 is movable along the X-axis guide rail 22 by a moving device including a motor and the like. The carriage 25 is freely movable along the Y-axis guide rail 23 by a traveling device having a motor and the like.
A second X-ray tube holder 26 is placed on the carriage 25,
The second X-ray tube 21 is held by the 2X-ray tube holding section 26 so as to be rotatable around the X axis and the Y axis. The second X-ray tube 21 is rotatable by a driving device such as a motor.

The third unit C includes a pair of X-axis guide rails 32 laid over the ceiling in the X-axis direction, and the X-axis guide rails 32.
And a Y-axis guide rail 33 that is disposed below and in a direction orthogonal to the X-axis guide rail 32 (Y-axis direction) and is movable along the X-axis guide rail 32. It comprises a trolley 35 movably disposed, a boom 36 provided at the bottom of the trolley 35 and capable of vertically expanding and contracting, and an X-ray processing unit 31 provided at the tip of the boom 36.

X-axis guide rail 32, Y-axis guide rail 33, bogie 35,
The boom 36 has the same structure as that of the first unit A.

A holding section 37 is provided at the tip of the boom 36 so as to be rotatable in the horizontal direction, and the X-ray processing section 31 is held by the holding section 37 so as to be rotatable in the vertical direction.

A cassette film for X-ray photography is housed in the X-ray processing unit 31 so as to be freely taken in and out, and X-rays irradiated from the first X-ray tube 11 and the second X-ray tube 21 are received by this film. The film is exposed.

Next, the use of the thus configured X-ray imaging apparatus will be described.

First, after placing the test object such as a racehorse at the inspection position,
Select the first X-ray tube 11 and the second X-ray tube 21 according to the inspection location, and operate the first X-ray tube 11 or the second X-ray tube 21 and the Y-axis guide rails 13, 23, carts 15, 25, and boom 16 Then, it is rotated in an appropriate direction and arranged at an appropriate position in the vicinity of the inspection object such as a racehorse. Next, the first X-ray tube 11 or the second X-ray tube 21
The X-ray processing unit 31 is disposed at a position facing the inspection object via the inspection object. Then, X-rays are emitted from the first X-ray tube 11 or the second X-ray tube 21. The irradiated X-rays pass through the inspection object and are received by the X-ray processing unit 31, whereby the film of the X-ray processing unit 31 is exposed, and X-ray imaging is performed.

As described above, one of the first X-ray tube 11 and the second X-ray tube 21 which is suitable for the imaging position of the object to be inspected is selected and arranged.
By performing the line imaging, it is possible to easily image all the inspection points even on a large inspection object such as a racehorse.

(Effects of the Invention) As described above, according to the present invention, the first X-ray tube 11 and the
2 Select one of the X-ray tubes 21 that is appropriate for the location of the object to be inspected and arrange it, and perform X-ray imaging, so that all inspection points can be easily performed even on large objects such as racehorses. An image can be taken, and the object to be inspected can be sufficiently inspected.
