Description
Technical field
The present invention relates to technical field of image processing, more particularly, it relates to a kind of formation method.
Background technology
In x-ray imaging mode, use X-ray beam to be irradiated on region, form whole district by projection
Image in territory.Similarly, NMR (Nuclear Magnetic Resonance)-imaging mode (MRI) and CT Scan imaging mode
(CT), by the data needed in gathering certain region, then the image in whole region is reconstructed.
In some imaging modes, such as, ultra sonic imaging, optical coherence tomography and terahertz imaging etc.,
Imaging typically has one-dimensional to the three-dimensional stage, such as single location, two dimension (2D) image and three-dimensional (3D)
Image.By some scan types, such as manual, machinery or electron scanning, substantial amounts of low-dimensional can be gathered
Degree image, for constructing high-dimensional image, such as, from 2D to 3D.In general, this is one
The most time-consuming program, particularly when sweep limits is bigger (for single frames imaging window).Cause
This, these imaging modes are incremented by formula in fact.But, within the most of the time of imaging, incrementally
Characteristics of image is not visible, because after sub-dimension image acquisition, equipment just illustrates complete image.
Meanwhile, the probe used in 2D imaging is used to form the 3D ultrasonoscopy on a large scale when needing longer
Between, the longest.
At present, there are some methods about incrementally imaging, but the purpose of these methods be,
Thered is provided quickly by incremental manner or show reconstructing part partial volume in real time, such as, in whole scanning process,
After gathering each Type B or a large amount of Type B image, incrementally present volumetric image rather than gathering institute
Image reconstruction is carried out, because generally carrying out image weight after gathering all desired datas after having desired data
Structure needs the relatively long time.At reconstruct and the aspect of display increasing volumes, certain methods can also provide
Three-dimensional orthogonal view.But, prior art is not directed to the principle of incremental imaging based on target, and right
In arbitrary imaging, it is most important that the target of imaging, such as the tumor in ultrasonoscopy and spine structure.
Summary of the invention
The technical problem to be solved in the present invention is, in place of the deficiencies in the prior art, it is provided that a kind of imaging
Method, relates to incremental imaging based on target.
The present invention solves the technical scheme of the problems referred to above and there is provided a kind of formation method, it is characterised in that should
Method comprises the following steps:

State multiple picture materials of target, and show described picture material in real time；
S4, by the plurality of picture material by be incremented by order arrangement, form the image of described target.
In the formation method of the present invention, this formation method farther includes:
Certain portion of the image of the most unimaged or described target of certain part in the image monitoring described target
During the poor image quality divided, by rescaning this part, this part is made to possess preferable picture quality.
In the formation method of the present invention, in described step S4, and by the plurality of picture material by passing
Before the order arrangement increased, also include carrying out between adjacent picture material uniform image processing and filtering operation.
In the formation method of the present invention, in described step S4, described incremental order is sweeping by target
Retouch what order determined.
