Abstract
The invention discloses an X-ray image calibrator, which comprises two parts, wherein the first part comprises a first binding tool and a calibration metal ball, wherein the first binding tool is bound at a joint which needs irradiation of X ray; the calibration metal ball is fixed on the first binding tool and has a preset size which is taken as a proportion reference in a formed image; the second part comprises a second binding tool, a calibration board and a plurality of metal balls, wherein the second binding tool is bound at a skeleton forming place of the joint; a plurality of small holes are arranged in the calibration board irregularly, and the calibration plate is slidably connected to the second binding tool; the metal balls are respectively fixed in the small holes for providing a spatial position reference in the formed image.
Description
Technical field
The present invention relates to medical diagnostic equipment technical field, particularly a kind of x-ray image calibration device.
Background technology
X-ray is widely used in medical domain, and the principle utilizing it to have an X-rayed is come skeleton, and soft tissue etc. carry out imaging, is convenient to the analysis in later stage.But, because X-ray light source is transmitted into receptor radially, the image of object is because object distance X-ray light source is near big and far smaller, and the image obtained can produce certain enlarge-effect, therefore, need to carry out further accurately measuring to normal rates to the figure adjustment obtained.
Existing x-ray image scaling method is by arranging Position Scale in X-ray receptor position, irradiates Position Scale estimate the distance angular surveying obtained in image by X-ray.But there is far and near distance with the joint itself of having an X-rayed in the receptor plane at Position Scale place, namely enlarge-effect is different, is not enough to reach accurate measurement effect.Secondly, this Position Scale likely needs repeatedly not adjust range of exposures when carrying out X-ray irradiation, and do not block, could meet the requirement of imaging, what add X-ray damages the radiating irradiation time.
Summary of the invention
The present invention is directed to prior art above shortcomings, provide a kind of x-ray image calibration device.The present invention is achieved through the following technical solutions:
A kind of x-ray image calibration device, comprises two parts:
Part I comprises:
First ties up tool, in order to be strapped in the joint that required X-ray irradiates;
One demarcate metal ball, be fixed on first and tie up on tool, demarcate metal ball there is a pre-set dimension, in order in become image as scale base;
Part II comprises:
Second ties up tool, in order to be strapped in the formation skeleton place in joint;
One scaling board, irregularly offers some apertures, and scaling board is slidably connected at second and ties up on tool;
Some metal ball, are separately fixed in aperture, in order to provide locus reference in become image.
Preferably, scaling board also offers elongated slot, ties up tool through second, to tie up on tool slidably second.
Preferably, scaling board is X-ray scaling board.
Preferably, demarcating metal ball is that after encapsulation to tie up tool by VELCRO and first bonding.
Can be realized by the present invention: 1, the distortion of corrected X mating plate and amplification, for the dimensional measurement of X-ray provides scale base; 2, calculate the space geometry site of multiple X-rays, provide position reference thus the observation realized in three dimensions, measurement and joint model foundation etc.
Accompanying drawing explanation
Shown in Fig. 1 is the structural representation of Part I of the present invention;
Shown in Fig. 2 is the structural representation of Part II of the present invention.
Detailed description of the invention
Below with reference to accompanying drawing of the present invention; clear, complete description and discussion are carried out to the technical scheme in the embodiment of the present invention; obviously; as described herein is only a part of example of the present invention; it is not whole examples; based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to protection scope of the present invention.
For the ease of the understanding to the embodiment of the present invention, be further explained for specific embodiment below in conjunction with accompanying drawing, and each embodiment does not form the restriction to the embodiment of the present invention.
As shown in Figure 1, the Part I of x-ray image calibration device provided by the invention comprises ties up tool 1, demarcates metal ball 2, packaging part 3 and VELCRO (not shown) for one.Wherein, tie up tool 1 and adopt OK diving cloth, its surface energy is bonding with VELCRO, demarcates metal ball 2 and is encapsulated in bag 3, and bonding with tiing up tool 1 by VELCRO.
Part I is used for the bondage of joint, because joint is likely case of bending, ties up on tool 1 so demarcation metal ball 21 is directly encapsulated in by packaging part 3.So, although under complete state, demarcate metal ball 21 and also can be fitted in periarticular completely.
As shown in Figure 2, the Part II of x-ray image calibration device provided by the invention comprises ties up tool 1, metal ball 22 and scaling board 4.In the irregular aperture 41 be distributed on scaling board 4 of metal ball 22, scaling board 4 offers two elongated slots 42, and tie up tool 1 through elongated slot 42, scaling board 4, tiing up on tool 1 and can slidably reciprocating, is convenient to adjusting position.Scaling board 4 is generally X-ray material.
Part II is mainly used in the skeletogenous bondage of joint structure, by the scaling board 4 in the some metal ball 22 of the irregular installation of skeleton place bondage, then multiple X-rays are taken from different perspectives, just by the locus of some metal ball 22, calculate the relative position relation of multiple X-rays, thus realize follow-up three-dimensional modeling after being integrated by multiple X-rays, therefore adopt scaling board 4 to provide locus reference.
In the present invention, demarcate metal ball 21 and there is a size preset, bondage is realized by tiing up tool and human synovial and forming skeleton, utilize x-ray fluoroscopy function, the metal ball 22 of demarcating in metal ball 21, scaling board is apparent in same X-ray with skeleton simultaneously, thus the function of two aspects is provided: 1, determine the size of metal ball 21 and comparing of actual size, the distortion of corrected X mating plate and amplification, for the dimensional measurement of X-ray provides scale base according to X-ray acceptance of the bid; 2, calculate the space geometry site of multiple X-rays according to metal ball 22, provide position reference thus the observation realized in three dimensions, measurement and joint model foundation etc.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
