Accompanying drawing explanation
Fig. 1 is a kind of figure of three-dimensional modeling method of the human organ that can carry out 3D printing.
Embodiment
Below in conjunction with embodiment and accompanying drawing, a kind of three-dimensional modeling method that can carry out the human organ of 3D printing of the present invention is described in detail.
As shown in Figure 1, a kind of three-dimensional modeling method that can carry out the human organ of 3D printing of the present invention, comprises the steps:
1) obtain histoorgan medical image,
Described histoorgan medical image is to adopt the mode of nuclear magnetic resonance or ultrasonic scanning obtain the image file of DICOM form and store; Wherein,
Nuclear magnetic resonance:
The Siemens 3T scanister of take is example, and Whole Body or single organ are carried out respectively to crown, sagittal, axial scan, and every layer of precision is 1.1 * 1.1mm, bed thickness 3mm, before layer and layer continuously every, obtain respectively the human organ image of three groups of different scanning modes, image is stored with DICOM form.The method does not have specific (special) requirements to nuclear magnetic resonance apparatus, as long as can obtain picture rich in detail in three directions.
Ultrasonic scanning:
The four-dimensional color ultrasound instrument of the Madison Multimedia Dynamic of take is example, and this instrument can carry out dynamic scan to human organ and fetus.After scanning completes, the mvl formatted file that scanning is generated imports Madison picture browsing software (3DXI PC Viewer) image is derived, and is stored as equally DICOM form, conveniently carries out next step image processing.
2) histoorgan medical image is utilized Medical Image Processing software Simpleware or Amira or Mimics in axial, sagittal and crown three directions, generate axial X-Y scheme, sagittal X-Y scheme and the crown two dimensional image of three homologs simultaneously;
3) to step 2) result carry out accordingly respectively axial vane surface separation of images, sagittal axial vane surface separation of images and crown axial vane surface separation of images, described separation of images is to carry out in Medical Image Processing software Simpleware or Amira or Mimics;
Specifically the image file of DICOM form is imported to the extraction of carrying out zone-by-zone analysis and organ edge in professional medical science image processing software Simpleware, this step is extremely important, and the quality of its last organ edge extracting directly has influence on the success or failure that three-dimensional organ of later stage is integrated.
4) to step 3) the separation of images result that the obtains three-dimensional of carrying out two dimensional image merges,
Described fusion is by step 3) three groups of image separate files obtaining import in computer aided design software Solidworks simultaneously and carry out manual amendment fusion, obtain model;
Specifically in axial, sagittal, crown three directions, generate the edge extracting figure (stl file form) of three homologs simultaneously, three groups of files are imported in computer aided design software (as Solidworks) simultaneously and merged, to guarantee that model can reflect real organ contours.
5) whether judgement fusion comes into force, and is to enter next step, otherwise turns back to step 3);
Whether described fusion comes into force, and refers to that the model of fusion reflects real organ contours, as differed too many with true organ.
6) in Medical Image Processing software, 3-D view is carried out to 3-D view Surface characterization, generate independent file and join in model, and save as STL formatted file;
7) model surface is carried out to smoothing processing and polishing processing,
Described carries out smoothing processing and polishing processing to model surface, is in STL formatted file importing Auto CAD software, to carry out level and smooth and polishing;
If model merges successfully, the now separation of organ completes substantially with structure, but some surface characteristics of organ still need to strengthen, and at this moment need to return in Medical Image Processing software image is carried out to detail extraction, such as the facial characteristics of fetus, generate independent file and join among model.Final mask saves as stl file form, imports and in Auto CAD software, carries out level and smooth and polish.
8) be generated as can 3 D-printing file: different depending on used three-dimensional printer, also different by the 3 D-printing file that stl file is converted.For example use MakerBot the 5th generation desktop printer, the 3 D-printing file layout of generation is .makerbot, and precision is 100 microns～300 microns;
9) whether the model that prints of judgement is true, is model generation, otherwise turns back to step 3).
The model printing should be three-dimensional lively, and smooth surface, can truly reflect the apperance of human organ, if do not meet this condition, should not return to step 3) again process.
Printer model needs propping material sometimes, and while removing propping material, care should be used to is careful, take and does not affect the outward appearance of model as main prerequisite.
Adopt a kind of three-dimensional modeling method that can carry out the human organ of 3D printing of the present invention to combine with 3D printer, simulated data is converted into 3D model, the fetus whole body generating or facial partial model can be used as neonate father and mother and leave another selection own and that household commemorates for, again because its data are all picked up from human body, the medical model generating is thus also more true to nature, and the improvement of medical lecture model is also had very great help.
