Abstract
The utility model provides a light -duty orthopedics CT machine, including the gamma ray source, flat panel detector, test bed and collecting computer, gamma ray source transmission X ray wherein, flat panel detector receives the X ray and into the signal of telecommunication of converting, flat panel detector is connected with collecting computer, test bed bearing patient, set up the fixed bolster around test bed, set up the contact sliding ring in the fixed bolster inboard, gamma ray source and flat panel detector be fixed the setting on the contact sliding ring respectively, and gamma ray source and flat panel detector set up and synchronous the rotation with the diameter is relative, the contact sliding ring is rotatory around test bed. Gather the image that obtains during gamma ray source and flat panel detector are rotatory and be two -dimensional projection, carry out the three -dimensional reconstruction by collecting computer again and can supply the doctor to diagnose the three -dimensional image of use. Because the X ray of gamma ray source transmission is the pulsed pencil -beam, therefore the utilization ratio of X ray is higher, only need rotatory a week can acquire the required whole original data of reconstructed image, accelerateed the picking rate of data.
Description
Technical field
This utility model relates to the technical field of clinical treatment apparatus, is a kind of light-duty orthopaedics CT machine of moveable, low radiological dose specifically.
Background technology
Computer tomography and CT are a kind of important Dynamic Non-Destruction Measurements, and the X-ray projection data under multiple projection view angles can be utilized to obtain two dimension or the 3-D view of the inside and outside architectural feature of object.It is with advantages such as harmless, high accuracy, three-dimensional visibles, and be widely used in clinical medicine diagnostic imaging, image is that the diagnosis of patient disease provides important foundation.But present many hospitals CT examination needs reservation, can not meet the demand of serious symptom, critical patient, be unfavorable for the timely treatment of emergency case sufferer; Along with China progresses into aging society, the resource of hospital will than now more in short supply.
In addition, traditional CT data for projection is one dimensional image, and the view data after rebuilding is two dimensional image, the 3-D view of finally recombinating is piled up by continuous multiple two dimension slicing to form, the metal artifacts of its image is comparatively serious, and traditional CT adopts fan-ray beam to scan, the radiological dose of ray is higher.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of light-duty orthopaedics CT machine of moveable, low radiological dose.
The technical scheme that this utility model is taked for the technical problem existed in solution known technology is:
Light-duty orthopaedics CT machine of the present utility model, comprise radiographic source, flat panel detector, detection bed and collecting computer, wherein radiographic source launches X-ray, flat panel detector receives X-ray and converts it to the signal of telecommunication, flat panel detector is connected with collecting computer, detect bed support patient, around detection bed, fixed support is set, contact slip ring is set inside fixed support, radiographic source and flat panel detector are fixedly installed on respectively and contact on slip ring, and radiographic source and flat panel detector are oppositely arranged and synchronous axial system with diameter, contact slip ring rotates around detection bed.
This utility model can also adopt following technical measures:
Described radiographic source is pulsed, rotary-anode X-ray source.
Between described radiographic source and detection bed, Bowtie is set and filters line device.
The advantage that this utility model has and good effect are:
In light-duty orthopaedics CT machine of the present utility model, the pulse radiographic source of synchronous axial system and dynamic flat panel detector are set, under the drive of the contact slip ring in fixed support, radiographic source and flat panel detector can rotate around detection bed, gather obtain image be two-dimensional projection, then carry out three-dimensional reconstruction by collecting computer can for the 3-D view of diagnosis.The X-ray of launching due to radiographic source is pulsed cone beam, and thus the utilization rate of X-ray is higher, and only need rotate a circle whole initial datas that can obtain and rebuild needed for image, accelerates the picking rate of data, and the quantity of X-rays X that radiographic source is launched is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation of light-duty orthopaedics CT machine of the present utility model;
Fig. 2 is that light-duty orthopaedics CT machine of the present invention ray emission operationally moves towards figure.
Detailed description of the invention
As depicted in figs. 1 and 2, light-duty orthopaedics CT machine of the present utility model, comprise radiographic source 1, flat panel detector 2, detect bed 5 and collecting computer, wherein radiographic source launches X-ray, flat panel detector receives X-ray and converts it to the signal of telecommunication, flat panel detector is connected with collecting computer, detect bed support patient 7, around detection bed, fixed support 3 is set, contact slip ring 4 is set inside fixed support, radiographic source and flat panel detector are fixedly installed on respectively and contact on slip ring, and radiographic source and flat panel detector are oppositely arranged and synchronous axial system with diameter, contact slip ring rotates around detection bed.
Radiographic source is pulsed, rotary-anode X-ray source, launches cone beam, thus makes the quantity of X-rays X that radiographic source keeps lower, reduces the radiation exposure of patient.
Between radiographic source and detection bed, Bowtie is set and filters line device 6, under the prerequisite not affecting image spatial resolution, improve the uniformity of image, improve the artifact of image border.
In light-duty orthopaedics CT machine of the present utility model, the pulse radiographic source of synchronous axial system and dynamic flat panel detector are set, under the drive of the contact slip ring in fixed support, radiographic source and flat panel detector can rotate around detection bed, gather obtain image be two-dimensional projection, then carry out three-dimensional reconstruction by collecting computer can for the 3-D view of diagnosis.The X-ray of launching due to radiographic source is pulsed cone beam, and thus the utilization rate of X-ray is higher, and only need rotate a circle whole initial datas that can obtain and rebuild needed for image, accelerates the picking rate of data, and the quantity of X-rays X that radiographic source is launched is lower.
The above, it is only preferred embodiment of the present utility model, not any pro forma restriction is done to this utility model, although this utility model with preferred embodiment openly as above, but, and be not used to limit this utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case be the content not departing from technical solutions of the utility model, according to any simple modification that technical spirit of the present utility model is done above embodiment, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
