Background technique
CT (Computed Tomography), i.e. CT scan, it be using Accurate collimation X-ray beam,
Section one by one is made at gamma-rays, ultrasonic wave etc., a certain position that human body is surrounded together with the detector high with sensitivity
The features such as scanning has sweep time fast, image clearly, can be used for the inspection of a variety of diseases；It is different according to used ray
Can be divided into: X ray CT (X-CT), ultrasound computed tomography (UCT) and gamma-rays CT(γ-CT) etc..CT is with X-ray beam to human body portion
Certain thickness level is scanned, and the X-ray for penetrating the level is received by detector, after being changed into visible light, is turned by photoelectricity
Transformation is electric signal, then switchs to number through analog/digital converter, inputs computer disposal.The processing that image is formed is just like right
Selected level is divided into the identical cuboid of several volumes, referred to as voxel.Scanning gained information is computed and obtains every individual
The x-ray attenuation coefficient or absorption coefficient of element are rearranged into matrix, i.e. character matrix, and character matrix can be stored in disk or light
In disk.Each number in character matrix is switched to by the black small cube to the white gray scales such as not, i.e. picture through digital/analog converter
Element, and be arranged in a matrix, that is, constitute CT image.In the patent document of Patent No. CN201711387440, one kind is disclosed
Medical image three-dimensional reconstruction system, the medical image three-dimensional reconstruction system include: the first user terminal, cloud storage server and
3-dimensional image generates server；First user terminal is used to obtain the patient information of clinical staff submission, and by institute
It states patient information and is sent to the cloud storage server and stored, the patient information includes at least the two-dimensional detection of patient
Image；The 3-dimensional image generates the two-dimensional detection image for the patient that server is used to send according to the cloud storage server
3-dimensional image model is generated, and the 3-dimensional image model of generation is sent to the cloud storage server and is stored.This hair
The medical image three-dimensional reconstruction system of bright offer, by the way that the two-dimensional detection image of patient is converted to 3-dimensional image model, thus
It no longer needs medical staff to envision human body organ three-dimensional structure by bidimensional image, and then error rate height can be reduced, favorably
In the accuracy for improving diagnosis.
