The specific embodiment
As described in the background art, in prior art, the success rate of image joint remains further to be improved.
The inventor finds, the movement of patient or making ruler all can cause the failure of impact splicing on the one hand, on the other hand, limbs image or deformation of image different with the amplification of making ruler image, cause the length of limbs image and shape untrue and cause and splice unsuccessfully.
The inventor further studies discovery, and the main cause of limbs image or deformation of image different with the amplification of making ruler image is due to making ruler and the limbs of patient height is inconsistent causes.Because X ray is a point source, after the X ray sent is coniform radiation irradiated body is irradiated, imaging on detecting devices thereunder, because X ray is coniform radiation, the imaging meeting has certain amplification.Because patient's skeleton has certain altitude, and there is certain difference in height between camera stand, plumbous chi makes the imaging of plumbous chi and limbs of patient have different amplifications from the difference in height between skeleton, image is caused to distortion, the length of limbs of patient image is untrue, thereby causes the image joint failure.
At present clinically, carrying out the splicing photography of clinostatism total length, is still that making ruler directly is placed on camera stand, without special equipment to fix and to adjust the height of plumbous chi.
The technical solution of the utility model, a kind of total length imaging marker chi device is provided, described total length imaging marker chi device comprises the altitude mixture control parts, the height of aignment mark chi easily, can adjust accordingly the height of making ruler for different patients, make making ruler and patient's skeleton position maintenance level, thus the distortion that reduction amplification and light cone effect cause image, the success rate of raising image joint.
For above-mentioned purpose of the present utility model, feature and advantage can more be become apparent, below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
