ʻEkolu-dimensional ultrasound imaging

ʻO nā kumu kumu o ke kiʻi kiʻi ultrasound ʻekolu-dimensional (3D) e komo pū ana me ke ʻano hana geometric ʻekolu-dimensional, ka hana contour extraction method a me ke ʻano kumu hoʻohālike voxel. ʻO ka pae kumu o ka 3D ultrasonic imaging ʻo ia ka hoʻohana ʻana i ʻelua-dimensional ultrasonic imaging probe e hōʻiliʻili i ke ʻano o nā kiʻi 2D i kekahi kaʻina spatial a mālama iā lākou i loko o ke kahua hana hou 3D. Hana ka lolouila i ka hoʻonohonoho spatial ma nā kiʻi 2D i hōʻiliʻili ʻia e like me kekahi lula a hoʻohālikelike i nā kiʻi. E kiʻi i ka ʻokoʻa ma waena o nā ʻāpana pili 2/12 Hoʻohui ʻia nā mea hoʻohui a hoʻomaʻamaʻa ʻia e hana i kahi waihona 3D, ʻo ia ka hana hope o ke kiʻi, a laila wehewehe ʻia ka wahi hoihoi, hana ʻia ke kūkulu hou ʻana 3D ma o ke kamepiula, a me ka Hōʻike ʻia ke kiʻi 3D i kūkulu hou ʻia ma ka pale kamepiula. ʻO ka ʻenehana kiʻi ultrasound 3D me ka loaʻa ʻana o ka ʻikepili, ke kūkulu hou ʻana i nā kiʻi ʻekolu a me ka hōʻike kiʻi ʻekolu. ʻO Baum lāua ʻo Greewood i hāpai mua i ka manaʻo o 3D ultrasound i ka makahiki 1961, akā ua lohi ka hoʻomohala ʻana i nā makahiki he 30 e hiki mai ana. I nā makahiki he ʻumi i hala iho nei, me ka hoʻomau mau ʻana o ka ʻenehana kamepiula a me ka ʻenehana kiʻi ultrasound, ua neʻe ʻo 3D ultrasound imaging ʻenehana mai ka pae noiʻi hoʻokolohua i ka pae noi lapaʻau [2], hiki ke māhele ʻia i (1) static 3D: ʻohi. kekahi helu o nā kiʻi 2D a laila hana i nā kiʻi pūʻulu 3D, a laila hana i nā hōʻike 3D like ʻole, i hoʻokaʻawale ʻia i 3D organ parenchyma a me 3D kahe kahe koko.
