Abstract
The utility model discloses an improved U-shaped arm of a digital radiography system. The U-shaped arm is marked with distance scales in an etching way or in a way of pasting a screen printing film. The measurement of the distance between an SID component and a detector can be conveniently measured through directly adding size marks on the U-shaped arm, thereby not only relieving the labor intensity of a doctor, but also effectively preventing the defect of high costs of elements and components in measurement of the distance between the SID component and the detector through encoder readings. Therefore, the utility model is an improvement of the U-shaped arm of the digital radiography system.
Description
Technical field
This utility model relates to the digital irradiation photography system technical field, is specifically related to a kind of improved digital irradiation photography system U-shaped arm.
Background technology
As shown in Figure 1, the arm-type digital irradiation photography system X ray of U camera chain comprises detector 1, U arm 2, column 3 and SID assembly (comprising light concentrator, bulb, ox head) 4, the operation principle of this system is: patient stand between detector 1 and the SID assembly 4, the doctor regulates the height of U arm 2 according to patient's height, make the center of detector 1 and patient chest on same horizontal plane, patient is close to the chest on the outer surface of detector 1 then, the mobile again SID assembly 4 of doctor, make it to move to desired location, when above all finish after doctor's film making that exposes again.
In use, the personnel that are taken are close to the position of its required shooting on the detector, produce X-rays by SID assembly 4, and by behind the human body by detector 1 imaging, by the pathological changes situation of spectral discrimination human body.Because tissue density's difference to each position of human body, so taking different parts is the distance that needs to regulate between SID assembly 4 and the detector 1, distance between SID assembly 4 and the detector 1 has very big influence to the effect of image, if range error too senior general causes poor image quality, so need accurately this distance of control when taking, what the range measurement form between SID assembly 4 and the detector 1 was common has two kinds: first kind is to use tape measure directly to measure after SID assembly 4 moves; Second kind is on SID assembly 4 kinematic chains encoder to be installed, thereby the feedback by encoder obtains the distance between SID assembly 4 and the detector 1.
The major defect of prior art is as follows:
First kind is directly used the method for tape measure very original, and the every motion of doctor once all needs to measure once, has increased doctor's labor intensity so greatly, and a people can't operate when distance is far away, needs two people to cooperate just and can finish.
The mode of second kind of employing encoder reading needs data processing platform (DPP)s such as PLC could realize this function, all these components and parts costs are just higher relatively, and electronic devices and components in use phenomenons such as error or mistake can occur because of many reasons, so the inaccurate phenomenon of range measurement that still might occur between SID assembly and the detector takes place.
The utility model content
The technical problems to be solved in the utility model provides a kind of improved digital irradiation photography system U-shaped arm, overcomes the mode that prior art is measured distance between SID assembly and the detector, and perhaps labor intensity is big, perhaps the components and parts defect of high cost.
This utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of improved digital irradiation photography system U-shaped arm, the mode with etching on described U-shaped arm marks distance scale.
Described improved digital irradiation photography system U-shaped arm, the mark scope of wherein said distance scale be 1000mm to 1800mm, the minimum range between scale and the scale is 10mm.
A kind of improved digital irradiation photography system U-shaped arm is pasted the silk-screen film on described U-shaped arm, mark distance scale on described silk-screen film.
Described improved digital irradiation photography system U-shaped arm, the mark scope of wherein said distance scale be 1000mm to 1800mm, the minimum range between scale and the scale is 10mm.
A kind of improved digital irradiation photography system U-shaped arm is fixed a metal chi on described U-shaped arm.
Described improved digital irradiation photography system U-shaped arm, the mark scope of the distance scale of wherein said metal chi be 1000mm to 1800mm, the minimum range between scale and the scale is 10m.
A kind of improved digital irradiation photography system U-shaped arm is fixed a plastic ruler on described U-shaped arm.
Described improved digital irradiation photography system U-shaped arm, the mark scope of the distance scale of wherein said plastic ruler be 1000mm to 1800mm, the minimum range between scale and the scale is 10mm.
The beneficial effects of the utility model: the improved digital irradiation photography system U-shaped of this utility model arm is by directly conveniently carrying out range measurement between SID assembly and the detector in the mode that increases size marking on the U-shaped arm, both alleviated doctor's labor intensity, having and avoided the high shortcoming of mode components and parts cost that adopts the encoder reading to carry out range measurement between SID assembly and the detector, is a much progress of digital irradiation photography system U-shaped arm.
Description of drawings
This utility model comprises following accompanying drawing:
Fig. 1 is a prior art digital irradiation photography system sketch map;
Fig. 2 be this utility model U-shaped arm and on block diagram.
The specific embodiment
With embodiment this utility model is described in further detail with reference to the accompanying drawings below:
As shown in Figure 2, detector 1 and SID assembly 4 have been installed on this utility model U-shaped arm 2, SID assembly 4 comprises light concentrator 41, bulb 42 and ox head 43, also is provided with distance scale 5 on this utility model U-shaped arm 2.
The improved digital irradiation photography system U-shaped of this utility model arm, can on U-shaped arm 2, the mode with etching mark distance scale 5, perhaps on U-shaped arm 2, paste the silk-screen film, mark distance scale 5 on the silk-screen film, perhaps on U-shaped arm 2, fix a metal chi, annotate distance scale 5 by the metal footage number, perhaps on U-shaped arm 2, fix a plastic ruler, by mark plastic ruler mark distance scale 5.
The mark scope of distance scale be 1000mm to 1800mm, the minimum range between scale and the scale is 10mm.
In whole digital irradiation photography system shooting process, it is a motion relatively more commonly used that the SID assembly moves, the doctor can select according to different patients and different positions, so every shooting a patient all may move, the doctor can be put bit time by the distance of distance scale embodiment intuitively shortens over half, traditional mode doctor whenever puts the position to a patient probably needs cost about 1 minute, and distance scale shows that the back only use took about 25 seconds but pass through intuitively.
Those skilled in the art do not break away from essence of the present utility model and spirit, can there be the various deformation scheme to realize this utility model, the above only is the preferable feasible embodiment of this utility model, be not so limit to interest field of the present utility model, the equivalent structure that all utilization this utility model description and accompanying drawing content are done changes, and all is contained within the interest field of the present utility model.
