Description
Technical field
This utility model relates to the wild consistency detection of the launched field light that is used for X-ray machine, particularly adopt the state of digital vedio recording (or taking pictures) technical notes to fluorescent screen induction radioluminescence, by wireless (or wired) thus be sent to the device that receiving system carries out the wild coherence measurement of launched field light of X-ray lamp.
Background technology
The light open country is meant that X ray camera head simulation light is in zone that the plane of incidence defined.Launched field is meant the projection of X-ray beam at the plane of incidence.
In clinical diagnosis is checked, because therefore launched field can't, simulate launched field with visible light usually by visual definite.The wild consistency detection of launched field light mainly is in order to verify the degree that overlaps of light and irradiation field, i.e. the degrees of offset on wild and launched field center or border of light.The wild consistency detection of launched field light mainly is used in the degree detecting that overlaps of medical X-ray diagnostic machine, clinac launched field and light open country.Being very one of the important performance indexes that is related to clinical use, is the testing tool that quality technical supervision detects department, health detection department, Medical Instruments testing agency, medical x-ray machine manufacturer, medical institutions at different levels indispensability.
The important function of the wild consistency detection of launched field light is: improve medical inspection efficient in the clinical diagnosis photography; Guarantee to be examined the integrity at position; Reduce the situation that occurs useless sheet because being examined the disappearance at position; Avoid the technical inessential irradiation of those who are investigated; Reduce the lifelong medical exposure dosage level of the public, reduce the cases of cancer that causes because of radiation.
The wild concordance plate of launched field light external as that Sweden produces, employing be that naked eyes watch twilight sunset behind the roentgenization to determine the method for range of exposures because after-glow brightness is low, naked eyes are difficult to know and define measuring range, and can not retention data.Domestic that what adopt is traditional film making method is more, has not only wasted film but also very bothersome time-consuming, and efficient is not high.
The problem of domestic and international similar present Research analysis and existence:
1, the problem of domestic similar present Research analysis and existence: the traditional film making method of domestic employing had both been wasted film, wasted time and energy again.
2, the problem of external similar present Research analysis and existence: (1) Ao Like multifunctional light open country/irradiation field consistency detection instrument, brightness decay is fast, but viewing time short (about 2 minutes), can not retention data; (2) can't carry out the collection of real time data, and measurement data be sent wirelessly (or wired transmission) to control end computer and carry out data analysis; (3) can't connect computer, carry out data and preserve and analytical work.
The utility model content
The purpose of this utility model provides a kind of wild consistency detection of the high launched field light of efficient system of measuring accurately, measure.
This novel purpose is achieved in that the wild consistency detection of a kind of launched field light system, comprises,
Fluorescent screen or rare earth intensifying screen: its surface is printed on graduated scale, and aligns with the light Yezhong heart of X ray ray machine;
Filming apparatus: by being fixed on photographic head on the bulb or camera video or the image when taking fluorescent screen induction radioluminescence;
Data transfer tool: be connected with the photographic head or the camera of filming apparatus, as receiving captured video or view data;
Receiving system: be connected with data transfer tool by wired mode or wireless mode, as receiving video or the view data of being transmitted;
Computer: be connected with receiving system, as judging the wild conforming degree of launched field and light;
Display device: be connected with computer, be used to show captured video or image;
Above-mentioned photographic head and camera are respectively data photographic head or digital camera.
Compared with prior art, this novel beneficial effect is:
1, realizes the repeated use of the wild consistency detection of launched field light.
2, realize the overall process monitoring of the wild consistency detection process of launched field light.
3, transfer of data fast, is conveniently conveniently preserved and is analyzed.
Native system does not use film, has the advantages that monitoring property is good, measurement reproducibility is high, certainty of measurement is high, and can realize being connected with computer, can use repeatedly, and both convenient and swift, safety is avoided radiation again, and saves resource, can repeated measure.
Description of drawings
Fig. 1 is this novel system principle diagram.
Fig. 2 is that fluorescent screen shows the wild situation schematic diagram of launched field light.
The specific embodiment
Fig. 1 illustrates, (among Fig. 2,1, the light open country; 2, the ray open country is the fluorescent screen light-emitting zone; Fig. 2 illustrates, the side-play amount a1 at directions X of launched field and light open country, a2 and at side-play amount b1, the b2 of Y direction.）
The wild consistency detection of this novel launched field light system comprises fluorescent screen (or rare earth intensifying screen), filming apparatus (equipment with digital vedio recording or camera function), data transfer tool (wireless or wired) and receiving system.
Fluorescent screen (or rare earth intensifying screen) can be sent fluorescence behind the roentgenization, its surface stamps graduated scale, and with the shadow center-aligned of X-ray production apparatus, zone that brightens owing to excitation of X-rays when shining by analyzing and visible light be the side-play amount of alignment area in advance, promptly knows the concordance situation of launched field and light open country.
Filming apparatus is a digital equipment, take the situation of fluorescent screen when illuminated by being fixed on (number) photographic head on the bulb or (number) camera, thereby can judge the wild conforming situation of launched field and light easily, avoid personnel directly to be subjected to roentgenization.
Data transfer tool is transferred to the illuminated luminous situation of fluorescent screen that measuring system measures on the corresponding receiver devices by wired or wireless mode, so that analyze and preserve data.
Receiving system is connected with computer.
Computer: be used as and read and preserve data, and judge launched field and the wild conforming degree of light.
Display device (being display) is connected with computer, is used to show and analyze the deviation of launched field and the wild concordance length and width of light both direction.
For example, use fluorescent screen, be equipped with wireless image and pick up and reading plotter NT1011, any computer (as the Think Pad of association) promptly constitutes a cover launched field and the wild consistency detection of light system.
