Raws li cov hauv paus ntsiab lus scanning, qhov ncauj peb-dimensional scanning technologies poob rau plaub yam tseem ceeb: kev sib cuag scanning, non-contact laser scanning, optical theem-hloov scanning, thiab radiographic-based scanning.
Hu rau Scanning TechnologyKev nrhiav tau cov ntaub ntawv yog pom tau los ntawm kev sib cuag lub cev ncaj qha ntawm kev sojntsuam scanning thiab cov khoom nto. Lub tshuab no ua tau zoo ntawm kev khaws cov ntsiab lus zoo ntawm qhov chaw thiab haum rau cov xwm txheej kho mob uas xav tau ultra-siab precision, xws li kho hniav thiab kho hniav. Txawm li cas los xij, nws muaj qhov teeb meem tseem ceeb: qhov ntsuas qis qis. Kev sib cuag ntawm lub cev ncaj qha ua rau muaj kev pheej hmoo ntawm kev raug mob rau cov ntaub so ntswg ntawm qhov ncauj, tshwj xeeb tshaj yog thaum kuaj cov cheeb tsam anatomical rhiab heev.
Tsis tiv tauj Laser Scanning TechnologyLaser beams yog npaj rau ntawm lub hom phiaj. Peb-dimensional coordinates yog xam los ntawm kev cuam tshuam laser teeb liab. Nws muab ceev scanning ceev thiab dlej raug, ua kom tau los ntawm loj 3D datasets nyob rau hauv ib lub sij hawm luv luv. Txawm li cas los xij, nws muaj qhov txwv tsis pub muaj. Tsis zoo laser reflection tshwm sim nyob rau hauv heev reflective los yog tsaus-xim xim, uas yuav ua rau cov ntaub ntawv scan tsis raug los yog tsis tiav.
Optical Phase-Shift Scanning TechnologyCov qauv txheej txheem ua ntej tau npaj rau ntawm cov khoom nto . 3D cov ntaub ntawv raug suav los ntawm kev txheeb xyuas cov qauv kev sib txawv los ntawm qhov chaw saum npoo av. Raws li cov txheej txheem tsis sib cuag, nws ua rau tsis muaj kev phom sij rau cov ntaub so ntswg ntawm qhov ncauj. Nws nta muaj zog adaptability thiab ua tau zoo nyob rau ntawm qhov chaw ntawm ntau yam ntaub ntawv thiab xim.
Radiographic-Based Scanning TechnologyCBCT (Cone-Beam Computed Tomography) yog ib daim ntawv tshwj xeeb ntawm qhov ncauj 3D scanning. Nws tau txais cov ntaub ntawv ntau lub kaum sab xis los ntawm kev sib hloov scanning. Khoos phib tawj algorithms reconstruct cov datasets los tsim volumetric peb-dimensional dluab. CBCT muab cov ntaub ntawv qhia tob tob txog cov qauv hauv qhov ncauj anatomical thiab ua lub luag haujlwm tseem ceeb hauv kev kuaj kab mob thiab kev npaj kho mob. Nws cov downsides suav nrog cov cuab yeej siv siab thiab cov hluav taws xob ntau dua, uas hu rau kev soj ntsuam nruj nruj thiab kev tswj xyuas kev siv.
