Matatu-dimensional ultrasound imaging

Misimboti yehutatu-dimensional (3D) ultrasound imaging inonyanya kusanganisira matatu-dimensional geometric composition method, performance contour extraction method uye voxel model method. Nhanho yakakosha ye3D ultrasonic imaging ndeye kushandisa maviri-dimensional ultrasonic imaging probe kuunganidza nhevedzano yemifananidzo ye2D mune imwe nzvimbo yekutevedzana uye kuichengeta mu 3D yekuvaka patsva yekushandira. Iyo komputa inoita nzvimbo yekumisikidza pamifananidzo ye2D yakaunganidzwa maererano nechero mutemo uye inoenzanisa mifananidzo. Mufananidzo mukaha pakati pezvikamu zviri padyo 2/12 Izvo zvinhu zvinowedzerwa uye zvakakwenenzverwa kuti zvigadzire 3D dhatabhesi, inova yekumashure-kugadzirisa kwemufananidzo, uye ipapo nzvimbo yekufarira inotsanangurwa, 3D kuvakwazve kunoitwa kuburikidza nekombuta, uye iyo yakagadziridzwa 3D mufananidzo unoratidzwa pane komputa skrini. 3D ultrasound imaging tekinoroji inosanganisira kutora data, matatu-dimensional mufananidzo wekuvaka uye matatu-dimensional mufananidzo kuratidza. Baum neGreewood vakatanga kupa pfungwa ye3D ultrasound muna 1961, asi kukura kwacho kwainonoka mumakore makumi matatu akatevera. Mumakore gumi apfuura, nekuenderera mberi kwekuvandudza tekinoroji yekombuta uye tekinoroji yekufungidzira, 3D ultrasound imaging tekinoroji yakatama kubva padanho rekutsvagisa kuenda kukiriniki yekushandisa nhanho [2], iyo inogona kukamurwa kuita (1) static 3D: kuunganidza. imwe nhamba yemifananidzo ye2D uyezve kugadzira mifananidzo yeboka re 3D, uye wobva waita zviratidzo zvakasiyana-siyana zve 3D, izvo zvakakamurwa kuva 3D organ parenchyma uye 3D yeropa rekuyerera kweropa.
