Abstract
The utility model is provided with an X-ray radiography scale whose base is connected with fix-length with mark line in a vertical way. One end of the fix-length is connected with the twist arm of a sliding sleeve and is orientated by a fixed knob, and the other end of the fix-length is connected with vernier with metal graduation. The X-ray radiography scale can improve the accuracy in radiography with nearly no error. At the same time, the X-ray radiography scale can lower the radiation dosage to the patients by reducing the photography repetition.
Description
Technical field
This utility model relates to X line photographic scale special-purpose in a kind of hospital image radiation work.
Background technology
At present, digitized photography hospitals at different levels become basically universal, and the post processing of image The Application of Technology has improved the photography photo quality, also make things convenient for and enlarged doctor's diagnostic area simultaneously.As everyone knows, the X line is with the conical radiation beams of focus as the summit, certain distance is all arranged between illuminated object limbs and film and the detecting plate, the amplification of this distance limbs image far away more is just big more, recent photo is also big more as amplification more to the limbs distance for focus, and the existing horizontal amplification of thicker limbs also has vertical amplification, when limbs are not that the limbs decentre line deformation of image that is exaggerated far away more is serious more when being positioned at X line center.Ordinary x-ray photography Jiao-limb distance and limb-pitch of fins relative fixed, flushing need not post processing image magnification ratio basically identical so film is directly through the darkroom.And that the digitized photography image needs work station to carry out the post-processed image is changeable, the design of scale Survey Software configures according to a certain Jiao-limb distance and limb-plate distance, but Jiao in real work-limb distance and limb-plate distance is skimble-scamble, amplification is also not exclusively the same, especially U type photography support and movable photography bed, the limb of at every turn photographing-plate is apart from disunities all.And the different laser cameras and the film size of different size, its image back gauge of the photo that prints is also different with image lattice spacing with image.Measure the pathological changes size for the clinician like this and very mistake appears in the artificial joint size, minimum error and maximum error can reach 8mm.
Summary of the invention
The purpose of this utility model provides a kind of accuracy rate that improves photographic objects, does not have error substantially, reduces unnecessary retaking simultaneously and reduces the X line photographic scale of patient's radiation dose.
The purpose of this utility model can realize by following technical measures:
The vertical scale that is connected with mark line on the base of this X line photographic scale, scale and sliding sleeve are slidingly connected and by the fixed knob location, the other end that an end connects the connecting lever of sliding sleeve is connected with the graduated vernier of metal.
This utility model is with respectively one of the plastic ruler of 10 centimetres of standards and 30 centimetres, at first with on 10 centimetres the plastic ruler master scale with 0.5 millimeter drill bit jewel hole, be cut into 1.5 millimeters long with the tinsel of 1 millimeter of diameter then and be embedded in the rule.30 centimetres plastic rulers are erected with plastic feet be stained with, 10 centimetres plastic rulers are fixed to the support vertical direction on 30 centimetres the plastic ruler, and can slide up and down with 502 glue.
The pathological changes at the clinical main application extremities joint of this utility model, vertebra, pelvis and each position is measured.Method is when photography this utility model laid parallel to be shone the next door, position in throwing, regulate this utility model height and throw according to the position aspect with high, exposure back this utility model just amplifies synchronously with diseased region, the size of the photo diseased region of shooting like this compares the size dimension that just can accurately measure the actual lesion position with projection of the present utility model.Measure and the photography of X line finds that the measured deviation on the digitized photography work station is bigger by material object, and behind use this utility model, the photo that the photo that prints carries out Measurement and analysis 90% does not have error, other 10% error only is ± 0.5 to 1mm.Use this utility model, improved the accuracy rate of photographic objects, reduced unnecessary retaking simultaneously and reduced patient's radiation dose.
