Ultrasonic imaging technology tau tsim rau ntau tshaj li ib nrab xyoo pua hauv Suav teb.Nrog rau kev txhim kho txuas ntxiv ntawm cov ntaub ntawv xov xwm hluav taws xob thiab khoos phis tawj thev naus laus zis, cov cuab yeej kuaj mob ultrasonic kuj tau hloov kho ntau zaus, los ntawm cov teeb liab analog / dub thiab dawb ultrasound / sib piv sib piv / kos duab kos duab, rau digital teeb liab / xim ultrasound / elastic imaging / Artificial txawj ntse.Cov haujlwm tshiab thiab daim ntawv thov qib txuas ntxiv nthuav dav, thiab cov cuab yeej siv tshuaj ntsuam xyuas ultrasonic txuas ntxiv tsim kho tshiab thiab tawg, ua rau kev lag luam kho mob muaj qhov xav tau loj heev rau nws.
01. Kev faib ua feem ntawm cov khoom siv kuaj ultrasonic imaging
Ultrasonic imaging diagnostic cov cuab yeej yog ib hom kev kuaj mob cov cuab yeej tsim raws li lub hauv paus ntsiab lus ntawm ultrasound.Piv nrog rau cov khoom siv kho mob loj xws li CT thiab MRI, nws cov nqi tshuaj ntsuam xyuas yog qhov qis, thiab nws muaj qhov zoo ntawm qhov tsis muaj kev cuam tshuam thiab lub sijhawm tiag tiag.Yog li ntawd, daim ntawv thov kev kho mob yog ntau thiab dav.Tam sim no, kev kuaj mob ultrasound yog kwv yees muab faib ua A-hom ultrasound (ib-dimensional ultrasound), B-hom ultrasound (ob-dimensional ultrasound), peb-dimensional ultrasound thiab plaub-dimensional ultrasound.
Feem ntau hu ua B-ultrasound, nws yeej yog hais txog dub thiab dawb ob-dimensional B-ultrasound, cov duab sau yog ib tug dub thiab dawb ob-dimensional dav hlau, thiab xim ultrasound yog cov ntshav sau cov teeb liab, tom qab lub computer xim coding ntawm daim duab ob sab hauv lub sijhawm tiag tiag superposition, uas yog, tsim cov xim Doppler ultrasound ntshav duab.
Peb-dimensional ultrasonic kuaj yog raws li xim Doppler ultrasonic kuaj ntsuas, cov ntaub ntawv nrhiav tau cov cuab yeej teeb tsa, thiab cov duab rov tsim dua yog ua los ntawm peb-dimensional software, thiaj li tsim cov cuab yeej kho mob uas tuaj yeem tso saib peb-dimensional imaging muaj nuj nqi, yog li ntawd. tib neeg lub cev tuaj yeem pom ntau dua stereoscopic thiab qhov txhab tuaj yeem pom ntau dua qhov xav tau.Plaub-dimensional xim ultrasound yog raws li peb-dimensional xim ultrasound ntxiv rau lub sij hawm vector ntawm plaub dimension (inter-dimensional parameter).
02 ib. Ultrasonic sojntsuam hom thiab kev siv
Nyob rau hauv cov txheej txheem ntawm kev kuaj xyuas cov duab, ultrasonic sojntsuam yog ib qho tseem ceeb ntawm cov cuab yeej kuaj xyuas ultrasonic, thiab nws yog ib qho cuab yeej uas xa thiab tau txais ultrasonic tsis nyob rau hauv cov txheej txheem ntawm ultrasonic nrhiav thiab kuaj.Qhov kev ua tau zoo ntawm kev sojntsuam ncaj qha cuam tshuam rau cov yam ntxwv ntawm kev ua haujlwm ntawm ultrasonic thiab ultrasonic nrhiav kom tau, yog li qhov kev sojntsuam tseem ceeb tshwj xeeb hauv kev kuaj xyuas cov duab ultrasonic.
Qee qhov kev sojntsuam pom zoo hauv ultrasonic sojntsuam feem ntau suav nrog: ib leeg siv lead ua convex array sojntsuam, phased array sojntsuam, linear array sojntsuam, ntim sojntsuam, kab noj hniav sojntsuam.
1, single crystal convex array sojntsuam
Cov duab ultrasonic yog cov khoom lag luam ntawm kev sib raug zoo ntawm kev sojntsuam thiab lub platform platform, yog li ntawm tib lub tshuab, software thiab kho vajtse yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua ntawm ib qho kev sojntsuam siv lead ua.
Ib leeg siv lead ua convex array sojntsuam txais cov khoom siv siv lead ua ib qho kev sojntsuam, qhov kev sojntsuam nto yog convex, kev sib cuag ntawm qhov chaw me me, cov duab thaij duab yog kiv cua, thiab nws yog dav siv hauv plab, obstetrics, ntsws thiab lwm yam txheeb ze. lub cev ntxaum.

2, phased array sojntsuam
Qhov kev sojntsuam nto yog tiaj tus, qhov chaw sib cuag me me, qhov chaw ze ntawm qhov chaw yog qhov tsawg, qhov chaw nyob deb yog qhov loj, thiab cov duab thaij duab yog kiv cua zoo li tus, uas haum rau lub plawv.
Kev sojntsuam plawv feem ntau muab faib ua peb pawg raws li daim ntawv thov pejxeem: cov neeg laus, menyuam yaus, thiab cov menyuam yug tshiab: (1) cov neeg laus muaj qhov tob tshaj plaws hauv lub plawv thiab qeeb qeeb;(2) Txoj hauj lwm ntawm lub plawv yug tshiab yog qhov ntiav thiab qhov kev ntaus nrawm yog qhov ceev tshaj plaws;(3) Tus mob ntawm cov me nyuam lub siab nyob nruab nrab ntawm cov me nyuam mos thiab cov laus.
Kev kuaj mob plawv
3, linear array sojntsuam
Qhov kev sojntsuam nto yog tiaj tus, qhov chaw sib cuag yog loj, daim duab thaij duab yog duab plaub, qhov kev daws teeb meem yog siab, qhov nkag mus tau qis, thiab nws yog qhov tsim nyog rau kev kuaj xyuas cov hlab ntsha, cov kab mob me me, musculoskeletal thiab lwm yam.

4, volum soj
Nyob rau hauv lub hauv paus ntawm ob-seem duab, lub ntim sojntsuam yuav tsis tu ncua sau lub spatial tis txoj hauj lwm, los ntawm lub computer reconstruction algorithm, thiaj li mus kom tau cov tiav spatial zoo.Haum rau: lub ntsej muag fetal, txha nraub qaum thiab caj dab.
Kev kuaj fetal
5, kab rov tav
Lub intracavitary sojntsuam muaj cov yam ntxwv ntawm cov zaus thiab cov duab siab, thiab tsis tas yuav sau lub zais zis.Qhov kev sojntsuam nyob ze rau ntawm qhov chaw kuaj mob, kom lub plab pelvic nyob ze thaj tsam ntawm lub suab nrov, thiab cov duab pom tseeb dua.
