Abstract

The utility model relates to an apparatus for detection, and provides a checker board for consistency of light field and radiation field of an X-ray apparatus, particularly aiming at detection on the consistency of the light field and the radiation field of X L-R CDB-1 type X-ray apparatus; the checker board is provided with at least two groups of rectangular scale marks and circular scale marks, and is also provided with a central scale mark and a positioning mark; and the checker board adopting the structure can effectively detect the consistency of the light field and the radiation field of the X-ray apparatus, is simple to operate, can be matched with the existing X-ray apparatus cassette for use, and improves the detection precision.

Description

Wild and the irradiation field consistency detection plate of X-ray machine light

Technical field

The utility model relates to a kind of detection utensil, is specifically related to a kind of at detecting the wild and conforming check-out console of irradiation field of X-ray machine light.

Background technology

X ray is a kind of electromagnetic wave or radiation that energy is arranged.When the material of any form of electron impact of high-speed mobile, X ray just might take place.X ray has penetrability, and the material of different densities is had different penetration capacitys.In human body, water is considered to X ray is seen through fully, sclerotin is considered to X ray is absorbed fully. so the homogeneous ray that X-ray machine is launched is a homogeneous no longer just seeing through different human body tissue back, these heterogeneous rays can or make the mode of light reaching the film be rendered as image by display screen. just can reflect some information of human tissue organ in view of the above, X-ray machine is the equipment that produces X ray, and it mainly is made up of X ray bulb and X-ray machine power supply and control circuit etc.

Because X ray is not a visible light, therefore the irradiation area (also claiming irradiation field) that only adopts X ray when medical application is the positioning irradiation measured target accurately, in order to address this problem, generally all adopt equivalence x-ray bombardment source, radiation of visible light source is set on X-ray machine, after adopting positioning irradiation zone, radiation of visible light zone (also claiming the light open country), use the method for x-ray bombardment again, can effectively address the above problem like this.But owing to can occur the skew of position after the long-term use of visible light source and x-ray source, therefore the inconsistent of X-ray machine light open country and irradiation field will appear, thereby the irradiation accuracy to X-ray machine brings bigger influence, existing metering method all can't detect this deviation accurately, does not also have special equipment that this is detected.

Summary of the invention

At the wild weak point that can't accurately judge with the irradiation field consistance of existing X-ray machine light, it is a kind of at X-ray machine light open country and irradiation field consistency detection plate that the utility model provides, especially at X L-R CDB-1 type X-ray machine light open country and the conforming check-out console of irradiation field, this check-out console is provided with at least two group rectangle scale marks and two groups of limbus lines, and be provided with center scale mark and witness marker, adopt the check-out console of this structure can effectively detect the wild consistance with irradiation field of X-ray machine light, simple to operate, can be used with existing X-ray machine magazine, handled easily has improved the precision that detects.

The concrete technical scheme that the utility model adopts is: the wild and irradiation field consistency detection plate of X-ray machine light, this check-out console surface is provided with at least two groups rectangle scale mark not of uniform size and limbus line, and is provided with center scale mark and witness marker.

After adopting this structure, in use, earlier X-ray film is positioned in the magazine, check-out console is placed on the magazine top, place under the X-ray machine visible light source, arbitrary group of rectangle scale mark of the wild irradiation of selective light keeps the invariant position of light open country, open X-ray machine and check-out console is shone make exposure, after the exposure film making with resulting roentgenogram launched field and ray on the X-ray sheet by check-out console after resulting scale mark contrast and can obtain deviation; Adopt another rectangle scale mark that uses the same method on the check-out console afterwards and shine, and obtain corresponding deviation.Again wild conforming detection of irradiation field by defined among JJG 744-2004, GB9706.12, the WS/T 189-19996.5 and light and computing method can record X-ray machine light wild with the irradiation field consistance.

Check-out console is provided with witness marker, X-ray machine light is wild during with the irradiation field consistency detection, and the witness marker that the exposure back obtains on X-ray film positions the position of X-ray machine light open country, with the position of determining that irradiation field departs from respect to the light open country, this witness marker generally adopts the form of shrinkage pool.

In order to satisfy among JJG 744-2004, GB9706.12, the WS/T 189-19996.5 to the light open country of X-ray machine and the requirement of irradiation field consistency detection, this check-out console is provided with many group rectangles and detects scale mark and the circular scale mark that detects, and labeled standards groove thereon, convenient to X-ray machine light wild estimate fast with the irradiation field departure degree read.

In order to improve the versatility of this check-out console, check-out console is provided with center groove and the circular scale mark that detects, and can be used with wire harness verticality test barrel like this, detects the perpendicularity of X-ray production apparatus bulb wire harness.

In sum, after adopting this check-out console, can can also can also be used for some projects detections of CR, DR to the centering detection of film loader and track and the perpendicularity that cooperates wire harness verticality test barrel detection X-ray production apparatus bulb wire harness to X-ray machine light open country and irradiation field consistency detection; And the measurement result that obtains after the exposure film making can be continued to employ file, be put on record as the foundation of check and maintenance; Can accurately measure each above-mentioned project, improve the precision of measuring, make things convenient for testing staff's use to improve detection efficiency, the usable range that has increased check-out console has reduced the cost that detects.
