Abstract
A radial center adjustment device belongs to a detector debugging technique in radiation imaging detecting, which comprises a detector and a secondary instrument of the detector, wherein the detector is equipped on a binary movement bracket which can adjust up and down or sideways. The detector receiver sends out radial beams and displays data on the detector secondary instrument. The utility model can avoid threats to personal safety and adjust the detector conveniently and quickly to the radial central beams to achieve high-quality detecting images. Comparing with the prior arts, the utility model has the advantages of simple conformation, low cost, convenient employment, safety and reliability.
Description
Technical field
The utility model relates to the detector debugging technique in the radiant image detection technique field, the particularly device that detector is aimed at the beam center.
Background technology
The radiant image checkout equipment is by X, gamma-ray powerful penetration capacity, has decay in various degree when passing different material according to ray, thereby obtains the image of checking matter.In general, for same radiation imaging apparatus, the roentgen dose X rate is high more, and image quality is good more.
Usually ray forms the beam of certain angle through the constraint that the radiographic source device goes out to restraint mouth.The beam dose rate exists the angle to distribute, difference is bigger with the difference of angle for dose rate under the same terms, wherein the dose rate of 0 ° of direction (beam direction) beam centerline direction is the highest, Fig. 1 shows be in the 9MeV accelerator relatively photon number with the different changes in distribution of output angle.In order to obtain high-quality image, we always wish to utilize the beam of center line part to reach optimum imaging effect.At present, we finish the task that detector is aimed at the beam center by the position of mobile detector manually and the combination of examination imaging usually, but this debugging needs repeated multiple times to carry out, and promptly consuming timely again workman's personal safety are constituted harm.
Goal of the invention
At the shortcoming that exists in the above-mentioned prior art, the purpose of this utility model provides a kind of beam centrally aligned device.This device can be avoided personal safety harm is made detector aim at the beam center line quickly and easily, thereby obtains high-quality detected image.
In order to reach above-mentioned goal of the invention, the technical solution of the utility model realizes as follows:
A kind of beam centrally aligned device, it comprises detector and detector secondary instrument.Its design feature is, described detector be installed in can about, on the two dimensional motion support of its position of left and right adjusting, detector receives beam that accelerator sends and data is shown by the detector secondary instrument.
In above-mentioned device, described support comprises base, support bar and cross bar.Support bar is vertical to be fixed with base, and cross bar can move up and down along support bar with vertical the connection also of support bar, and detector is connected with cross bar also can be along the cross bar move left and right.
The utility model is owing to adopted above-mentioned structure, detector can be finished horizontal and vertical two dimensional motion by machinery, remote control or manual mode, and the user observes the reading of detector secondary instrument just can find out the highest point of dose rate in the plane vertical with the beam center line.Compare with prior art, the utility model is simple in structure, with low cost, and is convenient to use, safe and reliable.
Below in conjunction with accompanying drawing and specific implementation method the utility model is described further.
Description of drawings
Fig. 1 is the angle distribution schematic diagram of accelerator dose rate;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the beam vertical view of the utility model when application feature;
Fig. 4 is the beam side view of the utility model when application feature.
Embodiment
Referring to Fig. 2, the utility model comprises detector 2, detector secondary instrument 5 and support.Support comprises base 4, support bar 1 and cross bar 3.Support bar 1 is vertically fixed on the base 4, and cross bar 3 and support bar 1 be vertical to be connected and can to move up and down along support bar 1, and detector 2 is connected with cross bar 3 and along cross bar 3 move left and right.Thus, detector 2 can about, move left and right.Detector 2 receives beam that accelerators send and data is shown by detector secondary instrument 5.
When using the utility model, set the relative position of radiographic source device 6 and the utility model device, for guaranteeing personal security, detector secondary instrument 5 is placed on outside the radiation protection district.Regulate the horizontal level of the detector 2 on the cross bar 3 by machinery, remote control or manual mode, make detector 2 move left and right.Find beam dose rate peak transversely by the reading on the detector secondary instrument 5.Regulate the upright position of cross bar 3 again by machinery, remote control or manual mode, drive detector 2 and move up and down, find the dose rate peak of beam on vertically by the reading on the detector secondary instrument 5 equally.As shown in Figure 3 and Figure 4.
In debugging during container check system, will speed up the device target spot as on the beam center line a bit, utilize the utility model device to find out the peak of dose rate in the beam scope easily again, just can identify the beam center line.From spot effect, the debugging work of using the utility model device will need just can finish in the past in 1 day is simplified to half an hour, very the time and labour saving.
