The specific embodiment

Describe below with reference to accompanying drawings and realize optimal mode of the present invention.The present invention is not limited in and realizes optimal mode of the present invention.Fig. 1 shows a kind of schematic structure of x-ray imaging system.This system realizes an example of optimal mode of the present invention.Utilize the structure of this system, shown and realized the example of optimal mode of the present invention about this x-ray imaging system.And, utilize the part of this system, shown and realized the example of optimal mode of the present invention about the X ray checkout equipment.

As shown in Figure 1, this system comprises x-ray bombardment equipment 200 and X ray checkout equipment 400.This x-ray bombardment equipment 200 comprises the x-ray source 220 that is attached to from suspended pillar 210 tips of top board.This x-ray source 220 is examples of the X-radiation device that defines in the present invention.

X-ray source 220 is adapted to change its direction to change the X-radiation direction.The pillar 210 in support X ray source 220 can stretch and shrink in a longitudinal direction, and can move horizontally along top board.

In X ray checkout equipment 400, balladeur train 420 vertically is attached to the pillar 410 perpendicular to ground movably, and arm 430 levels are attached to this balladeur train 420, and X-ray detector 440 is attached to the front end of arm 430.Arm 430 is examples of this arm of defining in the present invention.This arm 430 has handle 350 on its side.Handle 350 is examples of the handle that defines in the present invention.

X-ray detector 440 is plate-like structures, and its direction is variable, thereby makes its optical receiving surface become level or vertical according to the incident direction of X ray.X-ray detector 440 is examples of the X-ray detector that defines in the present invention.

The detection signal that provides from X-ray detector 440 is imported into operator's console 600.According to the detection signal that provides from X-ray detector 440, operator's console 600 is rebuild person under inspection's radiation and is observed image and demonstration on display 610.X-ray detector 440 can be the light-sensitive material for the X ray sensitivity.In this case, should radiate the observation image by development is rendered as visible.

Under the performed operation of operator, operator's console 600 this X-radiation equipment 200 of control and X ray checkout equipments 400.For X-radiation equipment 200, not only the X-radiation direction of the horizontal and vertical position of this x-ray source 220 and x-ray source 220 is controlled, and X ray intensity and radiation are regularly also controlled.For X ray checkout equipment 400, not only the height of this X-ray detector 440 is controlled to mate this x-ray source 220, and the direction of this optical receiving surface is also by according to the control of this X-radiation direction, thus the level of taking or plumbness or between the state between the two.

Pillar 410 has the balladeur train hoisting mechanism.Fig. 2 shows a topology example of this balladeur train hoisting mechanism.In Fig. 2, (a) be side view, (b) be front view.As shown in Figure 2, this balladeur train hoisting mechanism has pair of guide rails 502 and 504.This

guide rail

502 and 504 is installed on two sides of this pillar 410 abreast by the axle with this pillar.Balladeur train 420 provides slide block and the roller that is meshed with

guide rail

502 and 504 in inside, and can move along this

guide rail

502 and 504.

For mobile balladeur train 420, on two sides at the both ends of pillar 410, provide a pair of travelling gear 602,604 and a pair of driven gear 612,614 respectively.And chain 702 is transmitting on this travelling gear 602 and the driven gear 612 and is stretching between this two gear, and chain 704 is transmitting on this travelling gear 604 and the driven gear 614 and stretching between this two gear.This

chain

702 and 704 is fixed on the corresponding centre position of balladeur train 420.

According to this structure, when when being installed in this

travelling gear

602 and 604 of Motor Drive in the pillar 410 and rotating forward and backward, balladeur train 420 moves up and down along guide rail 502 and 504.Move both vertically by this of balladeur train 420, the upright position of X-ray detector 440 changes.

When balladeur train 420 stops, by this motor of lockings such as brake and fix the upright position of this X-ray detector 440.When this motor was unlocked, it is free that balladeur train 420 becomes, and in this state, can manually raise and reduce this X-ray detector 440.

Arm 430 is in conjunction with the direction of drive mechanism with change X-ray detector 440.Fig. 3 and 4 shows a topology example of this drive mechanism.Fig. 3 shows the X-ray detector 440 that is ordered about to level, and Fig. 4 shows the X-ray detector 440 that is ordered about to plumbness.In Fig. 3 and 4, (a) show the X-ray detector 440 that comprises balladeur train 420 and arm 430, and (b) show the X-ray detector 440 that has omitted balladeur train 420 and arm 430.

Shown in Fig. 3 and 4, this X-ray detector has support 442 in a side relative with this optical receiving surface, and this support 442 is fixed to the end of arm 430 by hinge 452.

One end of axle 460 is connected to support 442 by hinge 452.The other end of axle 460 is connected to slide block 470 by hinge 452.

Slide block 470 property guide rail 480 along the line moves horizontally.The operating side of linear actuator 490 is connected to slide block 470.

In Fig. 3, slide block 470 is in by promote to be moved near the state linear guides 480 left ends with linear actuator 490.At this moment, X-ray detector 440 turns clockwise by promoting to center on hinge 452 with axle 460, and its optical receiving surface is in level.

In Fig. 4, slide block 470 is in by be moved near the state linear guides 480 right-hand members with linear actuator 490 post-tensionings.At this moment, X-ray detector 440 is rotated counterclockwise by centering on hinge 452 with axle 460 tractives, and its optical receiving surface is in plumbness.

The handle 350 that provides on arm 430 is used for manually raising and reduces this X-ray detector 440.This state is shown in Fig. 5 (a).The manual operation that is used to raise and reduces this X-ray detector 440 is carried out under released state.Handle 350 has unlock switch.

Handle 350 also has the switch of the direction that is used to change X-ray detector 440.By operating this switch, can change the direction of X-ray detector 440, shown in Fig. 5 (b).Handle 350 and the handle 351 similar to handle 350 are provided at respectively on two sides of arm 430 so that can operate from either side, shown in Fig. 5 (c).

Fig. 6 shows the concrete structure of an example of handle 350.To shown in (f), handle 350 generally is a C shape as Fig. 6 (a).The two ends of this C shape handle 350 are attached to the side of arm 430.

Handle 350 has unlock switch 352 in the inboard of this C shape.This switch 352 is push switches.When operating this switch 352, for brake provides unlocking signal by forefinger.This switch 352 is examples of this first switch of defining in the present invention.

Handle 350 also is provided for changing the switch 354 of the direction of this X-ray detector 440 in the outside of this C shape.This switch 354 is push switches, and passes through the left end 354a or the right-hand member 354b of thumb manipulation pressing part.

By pushing left end 354a, the signal that for example is used for rotating in the horizontal direction this X-ray detector 440 is fed to this linear actuator 490, and by pushing right-hand member 354b, the signal that for example is used for rotating in vertical direction this X-ray detector 440 is fed to this linear actuator 490.This switch 354 is examples of this second switch of defining in the present invention.

In native system, because handle 350 is provided, so can save the height and the direction of this X-ray detector with a hand adjustment.Therefore, be very easy to realize radiography and help the person under inspection with another Handball Association.
