CT equipment 1 scans the location information that induction human body needs to repair, and generates corresponding body signal according to the information sensed.
Above-mentioned scanning answers the concrete principle of process as follows: X-ray tube sends x-ray bundle and scans needing the certain thickness aspect in position of repairing, the x-ray through this aspect is received by detector, after changing visible ray into, electric signal is changed into by photoelectric commutator, transfer digital signal to through analog/digital converter (analog/digitalconverter) again, this digital signal is sent to main control module 2 (as: computer software).
Above-mentioned mentioned digital signal and body signal, body signal is sent to main control module 2 by CT equipment 1.
Three-dimensional model signal according to body signal generating three-dimensional models signal, and is sent to segmentation module 3 by main control module 2.Segmentation module 3, according to the three-dimensional model signal received, generates print signal, and print signal is sent to 3D printer 4.
Detailed process is as follows: segmentation module 3 is software of the prior art, and segmentation module 3 is carried out layering to three-dimensional model, selected aspect is divided into the identical rectangular parallelepiped of several volumes, that is: voxel (voxel) after receiving three-dimensional model signal.Segmentation module 3 scans x-ray attenuation coefficient or the absorption coefficient that gained information obtains each voxel as calculated, rearranges into matrix, i.e. character matrix (digitalmatrix).Character matrix can be stored in disk or CD.Digital/analog converter (digital/anolog converter) through splitting module 3 transfers to each numeral in character matrix by the black blockage to the in vain gray scale such as not, i.e. pixel (pixel), and press matrix arrangement, namely the picture signal of CT equipment 1 is formed, segmentation module 3 generates print signal according to the picture signal of CT equipment 1, and print signal is sent to 3D printer 4.
3D printer 4 receives print signal, prints.
In the present embodiment, in order to better make site model conform to the position of human body reality, when can make 3D printer 4 print position model, site model and human body need the ratio at the position of repairing to be 1:1.In other embodiments, site model and human body need the ratio at the position of repairing also can adjust as required.
Site model comprises scar model, wound model and skeleton model.Scar model and wound model are the surface model at the position of patient, can learn the damage on patient positions surface and the size of each scar and thickness, can learn whether subjects bones pathology occurs by skeleton model by scar model and wound model.
In the present embodiment, the print signal that 3D printer 4 receives can be Gcode code, separates and converts CT equipment 1 picture signal to Gcode code, and send to 3D printer 4.
Fig. 2 schematically show the burn shaping of one embodiment of the present invention and surgical wound repair in the application flow of 3D printing technique as follows:
S101. first, CT equipment 1 is utilized to scan the location information of induction human body needs reparation;
S102. after, CT equipment 1 generates the body signal of patient according to the information of induction, and body signal (i.e. CT equipment 1 send digital signal) is sent to main control module 2;
S103. main control module 2 is according to body signal, generates the three-dimensional model signal corresponding with body signal; Namely this process is the process that main control module 2 carries out three-dimensional modeling.
S104. control module and three-dimensional model signal is sent to segmentation module 3;
S105. split module 3 according to three-dimensional model signal, generate print signal, printing is sent to 3D printer 4; Specific as follows: segmentation module 3 first carries out layering to three-dimensional model, then generate CT equipment 1 picture signal, picture signal is converted by CT equipment 1 to the Gcode code that 3D printer 4 can identify.
S106. receive print signal by 3D printer 4, print the site model of patient.
Utilize the 3D print system in the present invention and can site model be printed, making patient and family members thereof see the situation of oneself damage location intuitively, the situation of patient can be explained before the surgery intuitively to patient, in case there is unnecessary contradiction.3D print system in the present invention can also print the site model of any needs, for in medical education, anatomical structure and the neighbouring relationship of various organization can be shown to student, thus change anatomic teaching on the spot traditionally, save dissec resource and turn improve quality of instruction.
Above is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
