Izimiso eziyisisekelo zokuthwebula izithombe ze-ultrasound enezinhlangothi ezintathu (3D) ikakhulukazi zihlanganisa indlela yokuqamba ye-geometric enezinhlangothi ezintathu, indlela yokukhipha ikhonsathi yokusebenza kanye nendlela yemodeli ye-voxel.Isinyathelo esiyisisekelo se-3D imaging ultrasonic ukusebenzisa i-imaging probe enezinhlangothi ezimbili ukuze uqoqe uchungechunge lwezithombe ze-2D ngokulandelana okuthile kwendawo futhi uzigcine endaweni yokusebenza yokwakhiwa kabusha kwe-3D.Ikhompuyutha yenza ukuma kwendawo ezithombeni ze-2D eziqoqwe ngokomthetho othile futhi iqhathanisa izithombe.Isithombe igebe phakathi kwezigaba eziseduze 2/12 Izinto ziyengezwa futhi zenziwe bushelelezi ukuze zenze isizindalwazi se-3D, okuwukucutshungulwa kwangemuva kwesithombe, bese indawo ethakaselwayo ichazwa, ukwakhiwa kabusha kwe-3D kwenziwa ngekhompyutha, futhi isithombe se-3D esakhiwe kabusha siboniswa esikrinini sekhompyutha.Ubuchwepheshe bezithombe ze-3D ultrasound buhlanganisa ukutholwa kwedatha, ukwakhiwa kabusha kwesithombe esinezinhlangothi ezintathu kanye nokuboniswa kwesithombe esinezinhlangothi ezintathu.U-Baum no-Greewood baqale bahlongoza umqondo we-3D ultrasound ngo-1961, kodwa ukuthuthukiswa kwakuhamba kancane eminyakeni engu-30 elandelayo.Eminyakeni eyishumi edlule, ngokuthuthuka okuqhubekayo kobuchwepheshe bekhompiyutha kanye nobuchwepheshe be-imaging be-ultrasound, ubuchwepheshe be-imaging be-3D ultrasound busukile esigabeni socwaningo lokuhlola ukuya esigabeni sokufaka isicelo somtholampilo [2], esingahlukaniswa sibe (1) i-3D emile: ukuqoqa. inombolo ethile yezithombe ze-2D bese wenza izithombe zeqembu le-3D, bese wenza imibukiso ehlukahlukene ye-3D, ehlukaniswe yaba i-3D yesitho se-parenchyma kanye neziteshi zokugeleza kwemithambo yegazi engu-3D.(2)Amandla
I-3D: Thatha izithombe eziningi ze-2D ezindaweni ezihlukene ngezikhathi ezihlukene bese uzifaka bese uzigcina.Bese usebenzisa i-ECG ukuze uhlanganise iphoyinti lesikhathi, futhi uhlanganise izithombe zangempela ezitholwe ngezikhathi ezihlukene zibe isithombe se-3D.Izithombe zizohlanganiswa ngokochungechunge lwesikhathi lwe-ECG bese zidlalwa futhi.Njengamanje, isetshenziswa kabanzi ezinhlelweni ezahlukahlukene nasezinxenyeni ezinjengenhliziyo, izifo zokubelethisa kanye ne-gynecology, izitho ezincane, imithambo yegazi kanye nesistimu ye-urogenital [3].Uma kuqhathaniswa ne-2D ultrasound, i-3D ultrasound ingabonisa ukwakheka kwe-anatomical enezinhlangothi ezintathu kanye nobudlelwano bendawo bezakhiwo zezicubu, inezinzuzo zokubonisa isithombe esinembile, futhi ingakala ngokunembile imingcele yokuxilonga yezokwelapha.
