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 intelligent multiple degrees of freedom hoop of the one diagnostic equipment.
Background technology
Since the beginning of this century be applied to clinical since, rapidly, increasing clinical oral specialty starts to contact this technology for Cone-Beam CT development.Cone-Beam CT, compared with traditional medicine CT, has many advantages: sweep limits is flexible, can scan specific diagnostic region, also can scan whole craniofacial regions; The precision of images is high: and according to the ratio between thing, be 1:1 by throwing, can carry out actual measurement; Sweep time is short; Radiation dose is little; Image artifacts is few; Requiring 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, special high-pressure generator and large thermal capacity X bulb that the unnecessary employing traditional CT of Cone-Beam CT is used, reduced cost.The appearance of planar array detector, increases the utilization rate of X ray, and single projection can obtain 2-D data.The development of the computer technologies such as GPU acceleration, makes the real-time three-dimensional reconstruction of Cone-Beam CT become possibility.
At present Cone-Beam CT is mainly used in and shows sclerous tissues's skeleton and the higher lacuna structure of tooth, structure of temporomandibular articulation and some contrasts, as paranasal sinuses, air flue, nasal cavity, pharyngeal etc.Conventionally adopt the mode of C type arm in conjunction with image system, single armed suspension structure as shown in Figure 1, x-ray source and detector are all suspended on a single armed, around imaging object, carry out full scan imaging, existing oral cavity Cone-Beam CT adopts this Scan Architecture exactly, and x-ray source and detector are rotated imaging by arm link around head.Because this single-arm suspension structure exists the poor problem of rotational stabilization, and this Scan Architecture all covers imaging object, is not suitable for the surgery intervene operation imagings such as nerve, spinal column.In addition, vertical structure is that radiographic source and detector position are fixed, and 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.
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 development 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, also can scan whole craniofacial regions; The precision of images is high: and according to the ratio between thing, be 1:1 by throwing, can carry out actual measurement; Sweep time is short; Radiation dose is little; Image artifacts is few; Requiring 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, special high-pressure generator and large thermal capacity X bulb that the unnecessary employing traditional CT of Cone-Beam CT is used, reduced cost.The appearance of planar array detector, increases the utilization rate of X ray, and single projection can obtain 2-D data.The development of the computer technologies such as GPU acceleration, makes the real-time three-dimensional reconstruction of Cone-Beam CT become possibility.
Summary of the invention
