Description
Technical field
The present invention relates to a kind of three-dimensional modeling imaging optimization method based on medical image.
Background technology
DICOM（Digital Imaging and Communications in Medicine）I.e. Digital imaging in medicine and
Communication, is the international standard of medical image and relevant information（ISO 12052）.What it defined that quality can meet clinical needs can
For the Medical Image Format of data exchange.DICOM is widely used in radiating medical, and angiocarpy imaging and treatment for radiation-caused disease are examined
Disconnected equipment（X-ray, CT, nuclear magnetic resonance, ultrasound etc.）, and in ophthalmology and dentistry etc., other medical domains obtain more and more deep
It is widely applied.Ten hundreds of with medical imaging devices, DICOM be most widely-installed medical information standard it
One.The current about 10,000,000,000 grades medical images for meeting dicom standard are used for Clinical practice.Since dicom standard in 1985
Since an edition issue, DICOM brings revolutionary change to Studies of Radiological Practice, and X-ray film is by the workflow of total digitalization
Replaced.Turn into the brand-new platform of Information Communication application just as Internet, DICOM makes the senior of " changing clinical medicine looks "
Medical image applications are possibly realized.Such as in emergency department, cardiac load test, the inspection of breast cancer, DICOM is doctor and disease
People services, and is the standard of medical imaging effectively work.
3D model files form during obj file.By Alias | Wavefront companies are 3D modeling and animation software "
A kind of standard of Advanced Visualizer " exploitations, is suitable for the mutual conductance between 3D software models, it is also possible to pass through
Maya reads and writes.
Prior art is typically to be converted to OBJ forms after reading DICOM file for the three-dimensional modeling of medical image, so
Although and OBJ forms are a kind of convenient and reliable forms for 3D models, due to automatic conversion, in order to retain
The accuracy of DICOM file, can cause the file size after conversion excessive and burr and rough problem.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of three-dimensional modeling imaging based on medical image
Optimization method, solve after prior art conversion file size is excessive and burr and rough problem.
The purpose of the present invention is achieved through the following technical solutions：A kind of three-dimensional modeling imaging based on medical image
Optimization method, comprises the following steps：
S1：Obtain the thin layer scanning image file of DICOM format；
S2：The file of DICOM format is converted to the file of OBJ forms, the file of described OBJ forms is made up of gengon；
S3：Obj file is optimized, including：
A, face of early declining：It is different according to organ type, remove for insignificant face after imaging；
B, face further drops：For the top layer of each organ, if the quantity in the face of gengon in certain area is more than certain value,
The region is repartitioned.
Described insignificant face includes gully, the inside of bone and the liver top layer of brain.
Described gengon is triangle body；The face of the described gengon in certain area is triangular facet.
It is described the region to be reclassified as by the region division being two triangular facets.
It is described the region be reclassified as manually repartitioning or machine is repartitioned.
Described thin layer scanning image includes CT images, MRI and DSA images.
The beneficial effects of the invention are as follows：Optimization side is imaged the invention provides a kind of three-dimensional modeling based on medical image
Method, mainly for the optimization of the medical image image that OBJ forms are converted to from DICOM format, reduces file big by face of early declining
It is small, by the further smooth organ surface in drop face and removal organ surface spikes so that the effect of later stage three-dimensional modeling is more preferable.
Brief description of the drawings
Fig. 1 is this method flow chart.
Specific embodiment
Technical scheme is described in further detail below in conjunction with the accompanying drawings：
As shown in figure 1, a kind of three-dimensional modeling imaging optimization method based on medical image, comprises the following steps：
S1：Obtain the thin layer scanning image file of DICOM format；
S2：The file of DICOM format is converted to the file of OBJ forms, the file of described OBJ forms is made up of triangle body；
S3：Obj file is optimized, including：
A, face of early declining：It is different according to organ type, remove for insignificant face after imaging；
Due to the gully of brain, the inside of bone（Marrow or through hole）Although it is the original that DICOM file is converted with liver top layer
Actual content in file, but it is not meaningful for observation after three-dimensional imaging and three-dimensional imaging, therefore in this implementation
In example, described insignificant face includes gully, the inside of bone and the liver top layer of brain.
The main purpose in face of early declining is to reduce file size, and the file of usual 1000M sizes is by can be with behind the face of early declining
It is narrowed to 10M or so.
B, face further drops：For the top layer of each organ, if the quantity of the triangular facet in certain area is more than certain value,
The region is repartitioned.Such as in a certain piece of zonule on bone top layer, 50 triangular facets of populated with so that should
Region seems unsmooth and jagged, and this step is just repartitioned the top layer in the region, such as be divided into 2 it is big
Triangular facet, and can be using manually repartitioning or by the way of machine is repartitioned.
Further the main purpose in drop face is smooth organ surface and removal organ surface spikes.
Described thin layer scanning image is swept including the thin layer under CT images, MRI and DSA images, i.e. ordinary meaning
Tracing can realize the flow of the present embodiment as the medical image for obtaining.
