Kujambula kwa ultrasound katatu-dimensional

Mfundo zikuluzikulu za atatudimensional (3D) ultrasound kujambula makamaka monga atatu azithunzithunzi geometric zikuchokera njira, ntchito contour m'zigawo njira ndi voxel chitsanzo njira. Mfundo yaikulu ya 3D akupanga kujambula ndi ntchito awiri azithunzithunzi akupanga kujambula kafukufuku kusonkhanitsa angapo 2D zithunzi zinazake okhudza malo zinayendera ndi kuzisunga mu 3D yomanganso workstation. Kompyutayo imapanga malo pazithunzi za 2D zomwe zasonkhanitsidwa motsatira lamulo linalake ndikufanizira zithunzizo. Fananizani kusiyana pakati pa magawo oyandikana nawo 2/12 Zinthuzo zimawonjezeredwa ndikusinthidwa kuti zipange nkhokwe ya 3D, yomwe ndikusintha pambuyo pa chithunzicho, kenako gawo lachidwi limafotokozedwa, kukonzanso kwa 3D kumachitika kudzera pakompyuta, chithunzi chomangidwanso cha 3D chikuwonetsedwa pakompyuta. Ukadaulo wojambula wa 3D ultrasound umaphatikizapo kupeza deta, kukonzanso kwazithunzi za mbali zitatu komanso mawonekedwe azithunzi zitatu. Baum ndi Greewood poyamba anakonza lingaliro la 3D ultrasound mu 1961, koma chitukukocho chinali chochepa kwambiri m'zaka 30 zotsatira. M'zaka khumi zapitazi, ndikukula kosalekeza kwaukadaulo wamakompyuta ndi ukadaulo wojambula wa ultrasound, ukadaulo wojambula wa 3D ultrasound wachoka pagawo la kafukufuku woyeserera kupita kumalo ogwiritsira ntchito zachipatala [2], womwe ungagawidwe (1) 3D static: kusonkhanitsa. chiwerengero cha zithunzi 2D kenako kupanga 3D gulu zithunzi, ndiyeno kupanga zosiyanasiyana 3D anasonyeza, amene anawagawa 3D limba parenchyma ndi 3D magazi chotengera otaya ngalande.
