Imigaqo esisiseko ye-3-dimensional (3D) imaging ye-ultrasound ibandakanya ubukhulu becala indlela yokubunjwa kwejometri ye-3-dimensional, indlela yokusebenza ye-contour extraction kunye nendlela yemodeli ye-voxel. Isinyathelo esisisiseko se-3D imaging ye-ultrasonic kukusebenzisa iprobe ye-imaging ye-ultrasonic-dimensional-dimensional ukuqokelela uthotho lwemifanekiso ye-2D ngokulandelelana kwendawo ethile kwaye igcinwe kwindawo yokusebenza yokuvuselela i-3D. Ikhomputha yenza ukubeka indawo kwimifanekiso ye-2D eqokelelwe ngokomgaqo othile kwaye ithelekisa imifanekiso. Umfanekiso umsantsa phakathi kwamacandelo akufutshane 2/12 Izinto ziyadityaniswa kwaye zigudiswe ukwenza isiseko sedatha ye-3D, ekuyiyo emva kokulungiswa komfanekiso, emva koko indawo yomdla ichazwa, ukwakhiwa ngokutsha kwe-3D kwenziwa ngekhompyuter, kwaye umfanekiso we-3D owakhiwe ngokutsha uboniswa kwiscreen sekhompyuter. Itekhnoloji yemifanekiso ye-3D ye-ultrasound ibandakanya ukufunyanwa kwedatha, ukwakhiwa kwakhona komfanekiso we-3-dimensional and three-dimensional image display. I-Baum kunye ne-Greewood zaqala ukucebisa ingqikelelo ye-3D ultrasound ngo-1961, kodwa uphuhliso lwalucotha kakhulu kwiminyaka engama-30 elandelayo. Kwiminyaka elishumi edlulileyo, kunye nophuhliso oluqhubekayo lweteknoloji yekhompyutha kunye neteknoloji ye-imaging ye-ultrasound, iteknoloji ye-3D ye-imaging ye-ultrasound iye yasuka kwinqanaba lophando lovavanyo ukuya kwinqanaba lesicelo seklinikhi [2], enokwahlulwa ibe (1) i-3D engaguqukiyo: ukuqokelela. inani elithile lemifanekiso ye-2D uze wenze imifanekiso yeqela le-3D, uze wenze iziboniso ezahlukeneyo ze-3D, ezahlulwe zibe yi-3D ye-parenchyma ye-organ kunye ne-3D ye-blood flow flow channels.

I-3D: Thatha imifanekiso emininzi ye-2D kwiindawo ezahlukeneyo ngamaxesha ahlukeneyo kunye negalelo kwaye uyigcine. Emva koko sebenzisa i-ECG ukudibanisa indawo yexesha, kwaye udibanise imifanekiso yokuqala efunyenwe ngamaxesha ahlukeneyo kumfanekiso we-3D. Imifanekiso iya kuhlanganiswa ngokoluhlu lwexesha le-ECG kwaye emva koko idlalwe kwakhona. Okwangoku, isetyenziswa kakhulu kwiinkqubo ezahlukeneyo kunye namalungu afana nentliziyo, ukubeleka kunye ne-gynecology, amalungu amancinci, imithambo yegazi, kunye nenkqubo ye-urogenital [3]. Xa kuthelekiswa ne-2D ultrasound, i-3D ultrasound inokubonisa imilo ye-anatomical ene-dimensional emithathu kunye nobudlelwane bendawo yezakhiwo zezicubu, ineenzuzo zokubonisa umfanekiso ocacileyo, kwaye inokulinganisa ngokuchanekileyo iiparitha zokuxilonga zonyango.
