Hais txog kev kuaj ultrasound

01 Kev kuaj ultrasound yog dab tsi?

Tham txog dab tsi ultrasound yog, peb yuav tsum xub to taub tias ultrasound yog dab tsi.Ultrasonic yoj yog ib hom suab yoj, uas belongs rau mechanical yoj.Lub suab nthwv dej nrog cov zaus siab tshaj qhov txwv siab ntawm qhov tib neeg lub pob ntseg tuaj yeem hnov ​​(20,000 Hz, 20 KHZ) yog ultrasound, thaum kho mob ultrasound zaus feem ntau yog li ntawm 2 txog 13 lab Hz (2-13 MHZ).Lub hauv paus ntsiab lus ntawm kev ntsuam xyuas ultrasound yog: Vim qhov ceev ntawm tib neeg lub cev thiab qhov sib txawv ntawm qhov ceev ntawm lub suab yoj tawm, ultrasound yuav tshwm sim nyob rau hauv ntau qib, qhov kev sojntsuam tau txais ultrasound los ntawm cov kabmob sib txawv thiab ua tiav los ntawm lub khoos phis tawj. daim ntawv ultrasonic dluab, yog li nthuav qhia lub ultrasonography ntawm txhua lub cev ntawm tib neeg lub cev, thiab tus sonographer soj ntsuam cov ultrasound kom ua tiav lub hom phiaj ntawm kev kuaj mob thiab kho cov kab mob.

02 Puas yog ultrasound muaj teeb meem rau tib neeg lub cev?

Ntau cov kev tshawb fawb thiab kev siv tswv yim tau ua pov thawj tias kev kuaj ultrasound muaj kev nyab xeeb rau tib neeg lub cev, thiab peb yuav tsum tsis txhob txhawj txog nws.Los ntawm lub hauv paus ntsiab lus tsom xam, ultrasound yog kev sib kis ntawm txhua yam kev co nyob rau hauv nruab nrab, thaum nws kis tau nyob rau hauv lub lom nruab nrab thiab irradiation koob tshuaj tshaj ib tug tej yam kev mob, nws yuav muaj ib tug haumxeeb los yog structural cuam tshuam rau cov lom nruab nrab, uas yog cov nyhuv lom. ntawm ultrasound.Raws li nws cov txheej txheem ntawm kev ua, nws tuaj yeem muab faib ua: cov nyhuv mechanical, thixotropic effect, thermal effect, acoustic flow effect, cavitation effect, thiab lwm yam. .Txawm li cas los xij, peb tuaj yeem tso siab tau tias tam sim no ultrasonic diagnostic instrument Hoobkas nyob rau hauv nruj raws li lub tebchaws United States FDA thiab Tuam Tshoj CFDA cov qauv, cov koob tshuaj nyob rau hauv qhov kev nyab xeeb, tsuav yog tsim nyog tswj lub sij hawm soj ntsuam, ultrasound soj ntsuam tsis muaj. ua mob rau tib neeg lub cev.Tsis tas li ntawd, Royal College of Obstetricians thiab Gynecologists pom zoo kom tsawg kawg plaub lub ultrasounds ua ntej yug menyuam, uas txaus los ua pov thawj tias ultrasounds raug lees paub thoob ntiaj teb tias muaj kev nyab xeeb thiab tuaj yeem ua tiav nrog kev ntseeg siab, txawm tias hauv fetuses.

03 Vim li cas qee zaum yuav tsim nyog ua ntej kuaj "Npua plab", "tso zis", "tso zis"?

Txawm hais tias nws yog "kev yoo mov", "tuav zis", lossis " tso zis", nws yog kom tsis txhob muaj lwm yam kabmob hauv plab los cuam tshuam cov kabmob uas peb yuav tsum tau kuaj xyuas.

Rau qee qhov kev kuaj mob hauv nruab nrog cev, xws li daim siab, bile, pancreas, spleen, raum cov hlab ntsha, plab hlab ntsha, thiab lwm yam, yuav tsum muaj lub plab khoob ua ntej kuaj.Vim tias tib neeg lub cev tom qab noj mov, lub plab zom mov yuav tsim cov roj, thiab ultrasound yog "ntshai" roj.Thaum ultrasound ntsib cov pa roj, vim qhov sib txawv loj ntawm cov pa roj thiab tib neeg cov ntaub so ntswg, feem ntau ntawm ultrasound yog tshwm sim, yog li cov kab mob hauv qab cov roj tsis tuaj yeem pom.Txawm li cas los xij, ntau lub plab hnyuv siab raum nyob ze lossis tom qab lub plab zom mov, yog li yuav tsum muaj lub plab khoob kom tsis txhob muaj kev cuam tshuam ntawm cov pa hauv plab hnyuv ntawm cov duab zoo.Ntawm qhov tod tes, tom qab noj mov, cov kua tsib hauv lub gallbladder yuav raug tso tawm los pab kev zom zaub mov, lub gallbladder yuav txo qis, thiab txawm tias tsis tuaj yeem pom meej, thiab cov qauv thiab kev hloov pauv txawv txav hauv nws yuav pom tsis tau.Yog li ntawd, ua ntej kev soj ntsuam ntawm daim siab, kua tsib, pancreas, spleen, plab cov hlab ntsha loj, raum cov hlab ntsha, cov neeg laus yuav tsum yoo mov ntau tshaj 8 teev, thiab cov menyuam yaus yuav tsum yoo mov tsawg kawg 4 teev.

Thaum ua ultrasound ntawm lub urinary system thiab gynecology (transabdominal), nws yog ib qhov tsim nyog yuav tau sau lub zais zis (tuav zis) thiaj li yuav qhia tau hais tias lub cev muaj feem xyuam rau kom meej meej.Qhov no yog vim tias muaj lub plab zom mov nyob rau hauv pem hauv ntej ntawm lub zais zis, feem ntau muaj cov pa cuam tshuam, thaum peb tuav cov zis tso rau hauv lub zais zis, nws yuav ua rau cov hnyuv "tawm", koj tuaj yeem ua rau lub zais zis kom pom tseeb.Nyob rau tib lub sijhawm, lub zais zis nyob rau hauv tag nrho lub xeev tuaj yeem pom tseeb dua ntawm lub zais zis thiab lub zais zis phab ntsa.Nws zoo li lub hnab.Thaum nws tau deflated, peb tsis tuaj yeem pom dab tsi sab hauv, tab sis thaum peb tuav nws qhib, peb tuaj yeem pom.Lwm yam kabmob, xws li prostate, uterus, thiab appendices, xav tau lub zais zis tag nrho ua lub qhov rais pob tshab rau kev tshawb nrhiav zoo dua.Yog li ntawd, rau cov khoom kuaj uas yuav tsum tau tso zis, feem ntau haus dej dawb thiab tsis tso zis 1-2 teev ua ntej kev ntsuam xyuas, thiab tom qab ntawd xyuas seb thaum twg muaj kev tso zis ntau dua.

Gynecological ultrasound peb tau hais los saum toj no yog kev kuaj ultrasound los ntawm phab ntsa plab, thiab nws yuav tsum tau tuav cov zis ua ntej kuaj.Nyob rau tib lub sijhawm, muaj lwm qhov kev kuaj mob gynecological ultrasound, uas yog, transvaginal gynecological ultrasound (feem ntau hu ua "Yin ultrasound"), uas yuav tsum tau tso zis ua ntej kuaj.Qhov no yog vim transvaginal ultrasound yog ib qho kev sojntsuam muab tso rau hauv tus poj niam qhov chaw mos, qhia lub tsev menyuam thiab ob lub appendages, thiab lub zais zis nyob rau hauv qab ntawm lub uterine appendages, thaum nws puv, nws yuav thawb lub tsev menyuam thiab ob. appendages rov qab, ua rau lawv deb ntawm peb qhov kev sojntsuam, ua rau cov duab tsis zoo.Tsis tas li ntawd, transvaginal ultrasound feem ntau xav tau kev tshawb nrhiav siab, tseem yuav ua rau lub zais zis, yog tias lub zais zis puv rau lub sijhawm no, tus neeg mob yuav muaj qhov tsis xis nyob dua, tuaj yeem ua rau tsis pom kev.

04 Vim li cas cov khoom nplaum?

Thaum kuaj ultrasound, cov kua pob tshab siv los ntawm tus kws kho mob yog tus neeg sawv cev sib txuas, uas yog cov dej-raws li polymer gel npaj, uas tuaj yeem ua rau kev sojntsuam thiab peb tib neeg lub cev sib txuas sib txuas, tiv thaiv huab cua los ntawm kev cuam tshuam ntawm kev ua haujlwm ntawm ultrasonic tsis, thiab zoo heev txhim kho qhov zoo ntawm ultrasonic imaging.Ntxiv mus, nws muaj cov nyhuv lubricating, ua rau kev sojntsuam ntau dua thaum zawv zawg ntawm tus neeg mob lub cev nto, uas tuaj yeem txuag tus kws kho mob lub zog thiab txo tus neeg mob qhov tsis xis nyob.Cov kua dej no tsis muaj tshuaj lom, tsis qab, tsis ua rau khaus, tsis tshua muaj kev tsis haum tshuaj, thiab yooj yim los ntxuav, qhuav sai, kos nrog cov ntaub ntawv mos lossis phuam so kom huv, lossis ntxuav nrog dej.

05 Tus kws kho mob, tsis yog kuv qhov kev kuaj mob "xim ultrasound"?
Vim li cas koj saib cov duab hauv "dub thiab dawb"

Ua ntej tshaj plaws, koj yuav tsum nkag siab tias xim ultrasound tsis yog xim TV hauv peb lub tsev.Clinically, xim ultrasound hais txog xim Doppler ultrasound, uas yog tsim los ntawm superimposing lub teeb liab ntawm cov ntshav ntws mus rau ob-dimensional duab ntawm B-ultrasound (B-hom ultrasound) tom qab xim coding.Ntawm no, "xim" qhia txog qhov xwm txheej ntawm cov ntshav ntws, thaum peb tig xim Doppler muaj nuj nqi, cov duab yuav tshwm sim liab lossis xiav ntshav ntws teeb liab.Qhov no yog lub luag haujlwm tseem ceeb hauv peb cov txheej txheem kuaj ultrasound, uas tuaj yeem cuam tshuam cov ntshav ntws ntawm peb lub cev ib txwm muaj thiab qhia cov ntshav ntawm qhov chaw mob.Daim duab ob-dimensional ntawm ultrasound siv cov qib grey sib txawv los sawv cev sib txawv ntawm cov kabmob thiab cov kab mob, yog li nws zoo nkaus li "dub thiab dawb".Piv txwv li, cov duab hauv qab no, sab laug yog cov duab ob sab, nws feem ntau qhia txog lub cev ntawm tib neeg cov ntaub so ntswg, zoo li "dub thiab dawb", tab sis thaum superimposed ntawm liab, xiav xim ntshav ntws teeb liab, nws dhau los ua xim zoo. "xim ultrasound".

Sab laug: "Dub thiab dawb" ultrasound Txoj cai: "xim" ultrasound

06 Txhua tus paub tias lub siab yog ib qho tseem ceeb heev.
Yog li dab tsi koj yuav tsum paub txog kev mob plawv ultrasound?
