Description
Technical field
The invention belongs to field of medical technology, be specifically related to a kind of medical apparatus and instruments, more specifically to the mobile X-ray diagnostic equipment and work system thereof.
Background technology
Conventional bulk layer CT imaging system is widely used to clinic, but owing to radiological dose is big, expensive, its application is typically confined to some larger general hospital.The appearance of Cone-Beam CT (CBCT), changes this present situation so that neurosurgery, oral surgery and spinal surgery can have the CT equipment of oneself, and the market demand is huge.
Since the beginning of this century starts to be applied to clinic, Cone-Beam CT quickly grows, and increasing clinical oral specialty comes into contact with this technology.Cone-Beam CT, compared with traditional medicine CT, has many advantages: sweep limits is flexible, can scan specific diagnostic region, it is also possible to scan whole craniofacial regions；The precision of images is high: and be 1:1 by throwing the ratio according between thing, actual measurement can be carried out；Sweep time is short；Radiation dose is little；Image artifacts is few；The requirement of correct position is low.The fast development of Cone-Beam CT has benefited from the development of cheap X-ray tube, planar array detector and computer technology.The appearance of cheap X-ray tube so that special high-pressure generator that Cone-Beam CT unnecessary employing traditional CT is used and big thermal capacity X bulb, reduces cost.The appearance of planar array detector so that the utilization rate of X-ray increases, single projection can obtain 2-D data.The development of the computer technologies such as GPU acceleration, makes the real-time three-dimensional of Cone-Beam CT rebuild and is possibly realized.
At present Cone-Beam CT is mainly used in display sclerous tissues's skeleton and the higher lacuna structure of tooth, structure of temporomandibular articulation and some contrasts, such as paranasal sinuses, air flue, nasal cavity, pharyngeal etc..C-arm is generally used to combine the mode of image system, as shown in Figure 1, x-ray bulb and flat panel detector are fixed on the C mouth two ends of C-arm, it is rotated by C-arm, it is when implementing after completing C-arm and patient puts position, X-ray production apparatus is directed at region of interest and carries out cone-beam imaging, but owing to the density of soft tissue is sufficiently close to, the imaging unintelligible when low contrast of existing Cone-Beam CT.Additionally, existing Cone-Beam CT typically uses vertical bit scan form, volume is relatively big, very flexible, it is impossible to meet the specific demand of neurosurgery and spinal surgery.Therefore, exploitation the miniaturization Cone-Beam CT that can carry out blur-free imaging equal to hard and soft tissue can will become future developing trend.
In order to solve above-mentioned difficulties, reduce technical difficulty and the R&D costs of the clinical CBCT system of research and development, we intend developing a set of super-resolution high-accuracy portable CBCT experiment porch, by developing high accuracy scanning motion system, x-ray imaging system, integrated control system, short scanning CBCT algorithm for reconstructing, grasp the core technology of CBCT, verification technique index.Cone-Beam CT, compared with traditional medicine CT, has many advantages: sweep limits is flexible, can scan specific diagnostic region, it is also possible to scan whole craniofacial regions；The precision of images is high: and be 1:1 by throwing the ratio according between thing, actual measurement can be carried out；Sweep time is short；Radiation dose is little；Image artifacts is few；The requirement of correct position is low.The fast development of Cone-Beam CT has benefited from the development of cheap X-ray tube, planar array detector and computer technology.The appearance of cheap X-ray tube so that special high-pressure generator that Cone-Beam CT unnecessary employing traditional CT is used and big thermal capacity X bulb, reduces cost.The appearance of planar array detector so that the utilization rate of X-ray increases, single projection can obtain 2-D data.The development of the computer technologies such as GPU acceleration, makes the real-time three-dimensional of Cone-Beam CT rebuild and is possibly realized.
Summary of the invention
The present invention has abandoned single armed suspension and vertical structure, use moveable high-precision rotary frame Scan Architecture, x-ray source and detector are fixed on moveable rotary rack, half cycle or complete cycle scanning imagery is carried out centered by imaging object, utilize the cone-beam CT imaging algorithm improved, can be with the internal structural information of three dimensional reconstructive CT object.This structure uses lands swinging frame, structure spin stabilization, and removable whole frame, when surgical operations such as nerve, spinal columns, operative region superjacent air space can be avoided, beneficially surgical.The maximum feature of this structure is to realize half cycle or complete cycle scanning imagery, greatly reduces radiation exposure dose, and at utmost protection patient and intervention doctor, reach the purpose of low-dose X-ray imaging.
In existing cone-beam CT imaging system, single armed suspension structure is x-ray source and detector is all suspended on a single armed, full scan imaging is carried out around imaging object, existing oral cavity Cone-Beam CT uses this Scan Architecture, x-ray source and detector to be carried out rotation tomography by arm link around head exactly.Owing to this single-arm suspension structure exists the problem of rotational stabilization difference, and imaging object is all covered by this Scan Architecture, is not suitable for the surgery such as nerve, spinal column and gets involved operation imaging.Additionally, vertical structure is radiographic source and detector position is fixed, determinand is placed on a rotatable object stage, and imaging process needs rotatable stage to obtain multi-angle projection imaging, the inapplicable medical imaging of this structure.
For overcoming the limitation of radiographic apparatus in prior art, it is an object of the invention to provide a kind of mobile X-ray diagnostic equipment and work system with matching.3 d data field has been expanded not only by integral cycle rotating imaging, and visual angle, local can also be added by inclination front and back and swing, there is high resolution, it is greatly improved doctor's assurance to patient's state of an illness, particularly in the aneurysmal interventional procedure of skull cerebrovascular, locally the conversion at visual angle facilitates doctor to observe the three-dimensional solid form of lesion vessels, such that it is able to accurately by microtubular feed to tumor locus, reduce misdiagnosis rate；The mobile X-ray diagnostic equipment reduces the consumption of contrast agent simultaneously, hence it is evident that improve radioprotective safety than conventional DSA inspection, because three-dimensional reconstruction completes in single exposure；Additionally, line can not only be overcome to be wound around, and overall structure is simple, effectively reduces integrally-built weight, fundamentally solves by rotationally-varying and the image shift distortion that produces and mobile inconvenience；Coordinated by intelligentized work platforms, it is to avoid during Traditional x-ray diagnosis, patient adjusts the complexity of attitude, control to complete the scanning of multiposition multi-angle by remote controller, substantially increase the convenience of diagnosis and the security and stability to X-ray operation.
