Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, the present invention is described in more detail by the following examples.
In this article, " schematically " expression " serves as example, example or explanation ", not should by being described to any diagram of " schematically " in this article, embodiment is interpreted as a kind of preferred or have more the technical scheme of advantage.
For making simplified form, only schematically show part related to the present invention in each figure, they do not represent its practical structures as product.In addition, being convenient to for making simplified form understand, there are the parts of identical structure or function in some figure, only schematically depict one of them, or only having marked one of them.
Fig. 1 schematically shows the axonometric chart of the X-ray apparatus 1 involved by one embodiment of the invention.
As shown in Figure 1, X-ray apparatus 1 of the present invention mainly comprises: for the mounting bed 20 that loads imaging object thing with from the vertical support 10 erected of mounting bed 20.Support 10 at least comprises: from the mounting vertical arm 11 that vertically erects of bed 20 and connect with vertical arm 12 and the horizontal arm 12 parallel with mounting bed 20.X-ray generating mechanism 30 for generation of X-ray is set on the top of horizontal arm 12.X-ray generating mechanism 30 comprises X-ray bulb (x ray generator) 31, for the fan 32 that cools bulb and the beam-defining clipper 33 X-ray being carried out to boundling.Wherein, X-ray generating mechanism 30 is installed as and can rotates relative to the top of the horizontal arm 12 of support 10.
In addition, the X-ray apparatus 1 of the present embodiment also comprises the mounting bed 20 for loading imaging object thing (not shown), when adopting X-ray apparatus 1 to carry out imaging, X-ray generating mechanism 30 launches X-ray to imaging object thing, and this X-ray receives at the tabular X-ray detector 40 through the bed board back side being arranged at mounting bed 20 after imaging object thing.This X-ray detector 40 is set to, and the surface of its tabular be arranged in parallel with the bed board of mounting bed 20, and can be driven by motor 21 and move horizontally along the long side direction loading bed 20.This is because, when needing to expose complete strip object (such as vertebrae), because the length of vertebra is much larger than the size of X-ray detector 40, therefore, need to drive X-ray detector 40 move to multiple position along the length direction (that is long side direction of mounting bed 20) of vertebrae and take several topographies respectively by motor.
In addition, in the present embodiment, X-ray apparatus 1 also comprises the expansion link mechanism 50 for connecting between X-ray generating mechanism 30 and X-ray detector 40.
As shown in Figure 2, this expansion link mechanism 50 comprises: the sleeve 51 be connected with X-ray detector 40 and be arranged at sleeve 51 sliding freely and the balladeur train 52 be connected with X-ray generating mechanism 30, and sleeve 51 can be swung in the plane of the plane orthogonal with X-ray detector 40 place by pivot constructed 53.In the present embodiment, pivot constructed 53 comprises the pivot 531 stretched out from X-ray detector 40 level and the axle sleeve 532 being arranged at pivot 531 periphery, and axle sleeve 532 is vertical with sleeve 51 is wholely set.In addition, balladeur train 52 comprises: the slide axially sliding bar 521 that is arranged on sleeve 51 freely and and one end vertical with sliding bar 521 along sleeve 51 are provided with the connecting rod 522 of X-ray generating mechanism 30.This connecting rod 522 is positioned at the horizontal arm 12 of support 10, and supporting is for can rotate around the direction of arrow C.
When motor drives X-ray detector 40 to move horizontally to the long side direction (arrow A direction) along mounting bed 20, axle sleeve 532 rotates around pivot 531, and then sleeve 51 swings in the plane of the plane orthogonal with X-ray detector 40 place, simultaneously sleeve 51 moves along with X-ray detector 40 also occurred level, now, sliding bar 521 to slide a segment distance (arrow B direction) along sleeve 51.Because sleeve 51 swings, thus drive sliding bar 521 to swing, and then drivening rod 522 rotates in (arrow C direction), thus make the X-ray generating mechanism 30 being arranged at connecting rod 522 rotate certain angle, make X-ray generating mechanism 30 just to X-ray detector 40.
In addition, compressorium 60 is provided with the protruding outside of sleeve 51 of expansion link mechanism 50.This compressorium 60 is arranged between X-ray generating mechanism 30 and mounting bed 20, for carrying out pressing operation to check object thing.
Referring to Fig. 3 A ~ Fig. 3 C, the application that application X-ray apparatus 1 of the present utility model carries out when long strip shape object health check-up is looked into is described.At this, be placed as example with the long side direction of strip object along the long side direction loading bed 20 and be described.
Fig. 3 A shows state when X-ray detector 40 is positioned at primary importance, and in this condition, X-ray detector 40 is positioned at immediately below X-ray generating mechanism 30.Sleeve 51 is parallel with the vertical arm 11 of mounting bed 20 with sliding bar 521, and is positioned at than vertical arm 11 more by the position of bed board.Now, sliding bar 521 is positioned at the position at the most depth place of sleeve 51.In this case, X-ray generating mechanism 30 emitting x-ray, and receive this X-ray beam S by X-ray detector 40, obtain the Part I topography about this object thus.
And then, as shown in Figure 3 B, motor drives X-ray detector 40 along the long side direction of strip object, namely the left side to drawing is moved horizontally to the second position, under this position, X-ray generating mechanism 30 emitting x-ray again, and receive this X-ray beam by X-ray detector 40, obtain the Part II topography about this strip object thus.
And then as shown in Figure 3 C, motor drives X-ray detector 40 to move to the 3rd position to the right side of drawing, in this position, X-ray generating mechanism 30 emitting x-ray again, and receive this X-ray beam by X-ray detector 40, obtain the Part III topography about this strip object thus.
Then these several topographies photographed are sent to image processing apparatus 70 (see Fig. 1) to splice, thus obtain the X ray image of complete strip object.
In the above-described embodiments, exemplified with the support vertically erected from mounting bed, but also for being provided separately with mounting bed, and the support of ceiling can be fixed on.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
