Description
Technical field
This utility model relates to the technical field of clinical treatment apparatus, is a kind of multi-detector orthopaedics tomoscanner 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.
It is this static intrinsic hypothesis that the mathematical model of computer tomography depends on scanned object.In CT scan process, when requiring data acquisition, patient is absolutely stationary, but in fact can there is the motion of autonomous or non-autonomous thus destroy concordance and the integrity of data for projection in patient in a scan, once move in data acquisition, will cause serious artifact appears in final CT image, even affect diagnosis.This problem more easily occurs in the Cone-Beam CT that data acquisition time is longer.Usually because operator and scan patients be not at same room, be difficult to the motion in Timeliness coverage scanning process, often judge whether patient moves according to the artifact of rebuilding image, once in motion artifact causes image to be difficult to diagnosis, just can rescan patient, the X-ray radiation dosage causing patient to be subject to increases by this.
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 multi-detector orthopaedics tomoscanner of moveable, low radiological dose.
The technical scheme that this utility model is taked for the technical problem existed in solution known technology is:
Multi-detector orthopaedics tomoscanner of the present utility model, comprise radiographic source, filter, flat panel detector, detect bed and collecting computer, wherein radiographic source launches X-ray, filter is arranged between radiographic source and flat panel detector, 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, multiple flat panel detector and multiple radiographic source are set in fixed support, each radiographic source is respectively along support bracket fastened radial direction towards detection bed, flat panel detector in fixed support is two rows be arranged in parallel, contact slip ring is set inside fixed support, filter is arranged on and contacts on slip ring and synchronously rotate around detection bed with contact slip ring.
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 filter is set.
The advantage that this utility model has and good effect are:
In multi-detector orthopaedics tomoscanner of the present utility model, multiple pulsed radiographic source and flat panel detector are set, flat panel detector in fixed support is two rows be arranged in parallel, can rotate around detection bed under the drive of the contact slip ring of filter in fixed support, during a certain radiographic source work, filter is namely with contacting link motion between radiographic source and the flat-panel detector of correspondence, gather X-ray with two of radiographic source correspondence position flat panel detectors side by side simultaneously, the image that flat panel detector obtains is two-dimensional projection, carrying out three-dimensional reconstruction by collecting computer again can for the 3-D view of diagnosis, same radiographic source correspondence generates two images, thus make scanning result more accurate.The X-ray of launching due to radiographic source is pulsed cone beam, thus the utilization rate of X-ray is higher, each radiographic source is relative with the position of flat panel detector to be detected bed and fixes, error during single radiographic source rotation work can be reduced, taken turns to operate by multiple radiographic source and flat panel detector, can obtain the whole initial datas rebuild needed for image, accelerate the picking rate of data, the quantity of X-rays X that each radiographic source is launched is lower.
