Sawirka ultrasound saddex-geesoodka ah

Mabaadi'da aasaasiga ah ee sawirka ultrasound saddex-geesoodka ah (3D) inta badan waxaa ka mid ah habka halabuurka joomatari ee saddex-geesoodka ah, habka soo saarista konturrada waxqabadka iyo habka qaabka voxel.Talaabada aasaasiga ah ee sawir-qaadista 3D ultrasonic waa in la isticmaalo laba-cabbir sawir-qaadista ultrasonic si loo ururiyo sawirro taxane ah oo 2D ah oo isku xiga oo meelo gaar ah lagu kaydiyo 3D-ga shaqada ee dib-u-dhiska.Kumbuyuutarku waxa uu ku sameeyaa meelaynta meel bannaan ee sawirada 2D ee la soo ururiyey si waafaqsan xeer gaar ah oo isbarbar dhigaya sawirada.Sawirka farqiga u dhexeeya qaybaha ku xiga 2/12 Cutubyada waa la xoojiyaa oo la simay si ay u sameeyaan database 3D ah, taas oo ah habaynta sawirka ka dib, ka dibna meesha xiisaha ayaa la xaddidayaa, dib-u-dhiska 3D ayaa lagu sameeyaa kombiyuutarka, iyo Sawirka 3D ee dib loo dhisay ayaa lagu soo bandhigay shaashadda kombiyuutarka.Farsamaynta sawirka ultrasound ee 3D waxaa ka mid ah helitaanka xogta, dib-u-dhiska sawirka saddex-geesoodka ah iyo bandhig muuqaal saddex-cabbir ah.Baum iyo Greewood ayaa markii ugu horreysay soo jeediyay fikradda ultrasound-ka 3D sannadkii 1961-kii, laakiin horumarku wuxuu ahaa mid gaabis ah 30-kii sano ee soo socda.Tobankii sano ee la soo dhaafay, iyada oo horumarinta joogtada ah ee tignoolajiyada kombiyuutarka iyo tignoolajiyada sawirka ultrasound, 3D ultrasound imaging technology ayaa ka soo guurtay marxaladda cilmi baarista tijaabada ilaa heerka codsiga bukaan-socodka [2], kaas oo loo qaybin karo (1) 3D taagan: ururinta tiro cayiman oo sawiro 2D ah ka dibna samaynta 3D sawiro kooxeed, ka dibna samee bandhigyo 3D kala duwan, kuwaas oo loo qaybiyay 3D parenchyma iyo 3D marinnada socodka dhiigga.(2) Firfircoon
