Description
Technical field
The invention belongs to technical fields, concretely relate to a kind of computed tomography teleprocessing system.
Background technique
Computed tomography CT(Computed Tomography) it is a kind of before not destroying object structures
It puts, the data for projection of certain physical quantity according to acquired in object periphery (such as velocity of wave, X linear light strong, electronics beam intensity), fortune
With certain mathematical method, by computer disposal, the two dimensional image in the specific level of object is rebuild and according on a series of
State the technology that two dimensional image constitutes 3-D image.Industry CT (ICT) is grown up on the basis of Medical CT, at present should
Technology is quickly grown, and is widely applied in the non-destructive testing of industrial equipment and product, and by international non-destructive testing
Boundary is known as optimal nondestructiving detecting means.
Early in 1917, Austrian mathematician J.Radon, which is just proposed, utilized the projection weight on object different directions
The Radon transformation for building image, provides theoretical basis for CT technology.But until the 70's of last century, with scientific skill
The rapid development of art, especially physics and computer science, the theory are just achieved [3].1963, American physicist
First proposition X ray computer tomography imaging theory of A.M.Cormak.1972, Britain EMI Company Electronic work
Cheng Shi doctor G.Hounsfild cooperates with neuroradiologist Ambrose, succeeds in developing First and is really practically applicable to medicine
Clinical cranium brain X ray computer tomography imaging device, i.e., so-called medicine CT.Subsequent CT technology is grown rapidly simultaneously
It takes the lead in being widely used first in medical domain.To currently, the development of CT technology is had been subjected to by scanning mode division
Five stages: wherein third generation CT is also known as wide-angle fan beam CT, and probe unit increases to 300 ~ 4000, can cover
Cover entire sectoring region.When scanning, test specimen only does continuous rotation movement, substantially reduces sweep time.
Forth generation CT replaces linear array detector using planar array detector, fan-delta sandbody is replaced using cone-beam scan, into one
Step improves scanning speed.
5th generation CT and spiral CT, its scanning mode are exactly radiographic source and detector synchronous rotary, checked object edge
Axial translational movement, this kind of mode speed is fast, precision is high, applied to the radiation that can greatly reduce patient's receiving in medical domain
Dosage.
For Medical CT, evening occurs more advanced than the several generations of front with higher in this five kinds of scanning modes
Detection efficiency and better practicability, however for industry CT then be not present this concept, be usually used in work at present
Industry CT's is third generation fan beam CT and forth generation Cone-Beam CT scanning mode.The scanning mode of 5th generation CT is exactly ray
Source and detector synchronous rotary, the axially translated movement of checked object, this kind of mode speed is fast, precision is high, is applied to medicine and leads
The dose of radiation of patient's receiving can be greatly reduced in domain.
In existing X ray computer tomography system, generally include CT hardware (comprising radiographic source, detector,
And movement mechanism etc.), CT original projection image acquisition system, the main modulars such as CT work station, in real work, CT is swept
The data for projection obtained during retouching, is transferred to CT work station by grid line, the CT reconstruction software root on CT work station
According to CT algorithm for reconstructing, two-dimensional projection data is reconstructed into three-dimensional voxel model, so as to show rendering three over the display
Image is tieed up, and various analyses and processing are carried out to image.Since the CT Raw projection data amount of acquisition is usually very big, and
The mathematical operation of CT algorithm for reconstructing is extremely complex, therefore, requires very high, CT 3-D image to the hardware configuration of CT work station
Reconstruct, and analysis shows that software is very expensive, increase the cost of terminal user.
In addition in actual user's scene, the different people that the image data that CT is obtained usually requires in being organized is checked,
Different people may be by different terminals, such as computer, plate, mobile phone etc., obtain the image information of certain CT scanning, because
The storage scheme of this image needs to be easy by multiple end-user access, and existing CT framework is only able to satisfy looking into for local user
It sees.
