Description
Technical field
The utility model relates to the field of medical instrument technology, are especially a kind of adjusting dress of CT X-ray beam collimator
It sets.
Background technique
Existing CT issues X-ray by bulb, and is irradiated on human body and is checked.It is different due to being detected on human body
The width of X-ray needed for position is all different, so before being irradiated to human body needing that first the width of X-ray speed is adjusted.
It just needs this when to use X-ray beam collimator, the size of opening is passed through by adjusting X-ray beam to adjust X-ray beam
Width.
Currently, there are two types of the structures of X-ray beam collimator, a kind of opening driving different fixations by single motor come
Adjust X-ray beam size.Itself the problem is that only several fixations openings of sizes, can not achieve step-less adjustment.It is another
It is to drive two light barrier foldings respectively by two motors, realizes the adjusting of X-ray beam width.Its specifically include a pedestal,
Two light barriers, two motors.Two of them light barrier can be opened and closed to be snug fit on pedestal, two motors respectively with two
Light barrier is connected, for driving two light barrier foldings.X-ray beam is passed through from the gap between two light barriers and is mapped to
On human body.Although the X-ray beam collimator of the above structure design can be realized the step-less adjustment of X-ray beam, but cost compares
Height, control is more complicated.
To solve the above-mentioned problems, this case is given birth to therefrom.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, and providing one kind can not only realize that X-ray beam is stepless
It adjusts, and at low cost, controls the simple CT regulating device of X-ray beam collimator.
To achieve the goals above, the technical solution of the utility model is as follows: a kind of adjusting of CT X-ray beam collimator
Device, including pedestal, two light barriers, driving mechanisms, two light barriers, which can be opened and closed to slide under the action of the driving mechanism, matches
Together on pedestal；The driving mechanism includes a motor, a screw rod, two nuts, two link blocks；The screw rod pivot joint
In the side of pedestal, it is connect with motor linkage；The screw rod is formed by oppositely oriented two sections, and two nut difference activities are matched
Together on two sections of screw rod；Two light barriers pass through two link blocks respectively and are connected with two nuts.
Further, the opening center between the middle position of two nuts and two light barriers is corresponding.
Further, it is mounted on belt wheel on the output shaft and screw rod of the motor, is set with belt between two belt wheels.
After adopting the above technical scheme, the utility model compared with prior art, has the advantage that the utility model CT
With the regulating device of X-ray beam collimator, two light barriers can be driven symmetrically to open and close by a motor, and then realize that X is penetrated
The step-less adjustment of line, structure is simple, at low cost；Furthermore, it is only necessary to guarantee to open between corresponding two light barriers in the center of X-ray beam
The center of mouth, the openings of sizes of any width can realize central symmetry, so that it is guaranteed that degree of regulation, it is difficult to substantially reduce control
Degree.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
It is as shown in the figure: 1, pedestal 2, light barrier 3, motor 4, screw rod 5, nut 6, link block 7, belt wheel 8, belt
9, track.
Specific embodiment
The utility model is further elaborated below by drawings and examples.
The regulating device of a kind of CT X-ray beam collimator as shown in Figure 1:, including 1, two light barrier 2 of pedestal, driving
Mechanism.Two light barriers 2 are snug fit on pedestal 1 by track 9 in symmetry status, and can be under the action of the driving mechanism
Realize folding.It is not above emphasis, the primary object of the utility model is the improvement to driving mechanism, to realize stepless-adjustment
Section, while simplifying structure, reduce cost.Driving mechanism is specifically connected by 3, one, a motor screw rod 4, two 5, two, nut
Block 6 forms.
Wherein, screw rod 4 is articulated in the side of pedestal 1, is connected with motor 3, and is driven and rotated by motor 3.This reality
It applies in example, belt wheel 7 is mounted on the output shaft and screw rod 4 of motor 3, belt 8 is set between two belt wheels 7, motor 3 passes through
The cooperation of belt wheel 7 and belt 8 drives 4 positive and negative rotation of screw rod.
Screw rod 4 is formed by oppositely oriented two sections, and activity is matched on two sections of screw rod 4 two nuts 5 respectively.The above institute
The thread rotary orientation stated on oppositely oriented two sections, in particular to this two sections is exactly the opposite.When screw rod 4 rotates, two nuts 5 can be in
The activity relatively of symmetry status.Two light barriers 2 are connected by two link blocks 6 with two nuts 5 respectively.When motor 3 drives
When 4 positive and negative rotation of screw rod, two nuts 5 can be driven in the relatively movable of symmetry status, and then two gears are driven by link block 6
Tabula rasa 2 moves left and right, the final purpose realizing light barrier 2 and opening and closing.For light barrier 2 during folding, opening center is always
It remains unchanged, and is able to achieve the adjusting of any opening, achieve the purpose that step-less adjustment.Above scheme only passes through a motor 3
It can be realized, structure is simple, at low cost.
In the present embodiment, the opening center between the middle position of two nuts 5 and two light barriers 2 is corresponding, meanwhile,
The center being open between the center of X-ray beam and two light barriers 2 is corresponding.It is designed in this way, the openings of sizes of any width is all
It is able to achieve central symmetry, so that it is guaranteed that degree of regulation, substantially reduces control difficulty.
