Kev debugging ntawm ultrasonic imaging diagnostic ntsuas
Ultrasonic imaging tau dav siv nyob rau hauv kev kuaj mob ntawm kev phais, hlab plawv, oncology, gastroenterology, ophthalmology, obstetrics thiab gynecology thiab lwm yam kab mob.Nyob rau hauv xyoo tas los no, ntawm ib sab, txoj kev loj hlob ntawm ultrasonic imaging diagnostic instrument tas li tshawb nrhiav qhov chaw kho mob ntawm daim ntaub ntawv tshiab, ntawm qhov tod tes, raws li lub ultrasound imaging nyob rau hauv kev kuaj mob ntawm kev paub thiab kev nkag siab ntawm kev ua tau zoo ntawm ultrasonic imaging ntsuas, kws kho mob thiab muaj nuj nqi. Nyob rau hauv qhov zoo ntawm ultrasonic imaging diagnostic instrument thiab feem ntau muab tso rau pem hauv ntej ntau yam yuav tsum tau thiab cov tswv yim, thiaj li hais tias tsis tsuas yog txhawb lub ultrasonography kev kuaj mob theem txhim khu unceasingly, Ntxiv mus, daim ntawv thov ntawm ultrasonic imaging tau tob, thiab cov diagnostic technology ntawm ultrasonic imaging tau tsim. .
1. Saib xyuas kev debugging
Txhawm rau kom tau txais cov duab zoo ntawm cov nqi kuaj mob, yuav tsum muaj ntau yam xwm txheej.Ntawm lawv, qhov debugging ntawm ultrasonic diagnostic ntsuas ntsuas yog ib qho tseem ceeb heev.Tom qab tus tswv tsev thiab tus saib xyuas yog powered on, thawj daim duab yog tso tawm kom pom ntawm qhov screen.Xyuas seb cov kab grey puas ua tiav ua ntej kev debugging, thiab muab tso rau tom qab ua tiav hauv lub xeev linear.Qhov sib piv thiab Light ntawm tus saib tuaj yeem hloov kho ntau npaum li qhov xav tau.Debug lub monitor kom haum, txawm tias nws txaus los cuam tshuam txog ntau yam kev kuaj mob cov ntaub ntawv muab los ntawm tus tswv tsev, thiab pom zoo rau tus kws kho mob lub zeem muag.Lub greyscale yog siv raws li tus qauv thaum lub sij hawm debugging, yog li ntawd qhov qis greyscale yog faintly pom nyob rau hauv dub.Qhov siab tshaj plaws grey qib yog cov cim dawb ci tab sis ci ntsa iab, kho kom haum rau txhua qib grey qib nplua nuj thiab tuaj yeem pom.
2. Kev paub debugging
rhiab heev yog hais txog lub peev xwm ntawm lub cuab yeej kuaj mob ultrasound los kuaj xyuas thiab tso saib qhov cuam tshuam cuam tshuam.Nws muaj tag nrho cov nyiaj tau los, nyob ze thaj tsam kev tawm tsam thiab kev them nyiaj rau tej thaj chaw deb lossis qhov nyiaj tau los tob (DGC).Tag nrho qhov nce yog siv los kho qhov amplification ntawm voltage, tam sim no los yog lub zog ntawm lub teeb liab tau txais ntawm ultrasonic diagnostic ntsuas.Qib ntawm tag nrho cov nce ncaj qha cuam tshuam rau cov duab ntawm cov duab, thiab nws qhov kev debugging tseem ceeb heev.Feem ntau, cov neeg laus lub siab ib txwm raug xaiv los ua tus qauv hloov kho, thiab cov duab tiag tiag ntawm daim siab uas muaj cov kab mob siab nruab nrab thiab cov kab mob siab hepatic tau tshwm sim los ntawm subcostal oblique incision, thiab tag nrho qhov nce tau raug kho kom lub suab nrov ntawm daim siab. parenchyma nyob rau hauv nruab nrab ntawm daim duab (4-7cm cheeb tsam) yog ze li sai tau mus rau lub grey teev tso tawm nyob rau hauv nruab nrab ntawm lub grey teev.Qhov tob nce nyiaj them (DGC) tseem hu ua lub sij hawm nce nyiaj them (TGC), rhiab lub sij hawm hloov kho (STC).Raws li qhov kev ncua deb ntawm qhov xwm txheej ultrasonic yoj nce thiab tsis muaj zog nyob rau hauv cov txheej txheem propagation ntawm tib neeg lub cev, lub zeem muag teeb liab feem ntau muaj zog, thaum lub teeb liab nyob deb tsis muaj zog.Txhawm rau kom tau txais cov duab ntawm qhov sib txawv ntawm qhov tob, kev tawm tsam ze ntawm thaj chaw thiab thaj chaw deb yuav tsum tau ua.Txhua hom kev ntsuas ultrasonic feem ntau siv ob hom kev them nyiaj: zoning tswj hom (txoj kab nqes tswj hom) thiab subsection tswj hom (nyob deb tswj hom).Nws lub hom phiaj yog ua kom lub suab nrov ntawm thaj chaw ze (cov ntaub so ntswg) thiab thaj chaw deb (cov ntaub so ntswg sib sib zog nqus) ze rau theem grey ntawm nruab nrab teb, uas yog, kom tau txais cov duab zoo ib yam los ntawm lub teeb mus rau qhov tob grey, thiaj li ua kom yooj yim rau cov duab hauv nruab nrab. kev txhais thiab kev kuaj mob ntawm cov kws kho mob.
3. Kev hloov ntawm dynamic ntau yam
Dynamic ntau yam (qhia hauv DB) yog hais txog qhov ntau ntawm qhov qis tshaj plaws mus rau siab tshaj ncha teeb liab uas tuaj yeem ua kom muaj zog los ntawm lub suab nrov ntawm ultrasonic imaging diagnostic instrument.Lub ncha teeb liab qhia rau ntawm daim duab hauv qab qhov tsawg kawg yog tsis tshwm sim, thiab lub ncha teeb liab saum qhov siab tshaj plaws yog tsis kho ntxiv lawm.Tam sim no, dynamic ntau yam ntawm qhov muaj zog tshaj thiab qis tshaj echo signals nyob rau hauv lub dav ultrasonic imaging diagnostic instrument yog 60dB.ACUSONSEQUOIA computerized ultrasound tshuab mus txog 110dB.Lub hom phiaj ntawm kev kho qhov dynamic ntau yam yog kom nthuav dav lub ncha teeb liab nrog cov txiaj ntsig tseem ceeb ntawm kev kuaj mob thiab txhawm rau txhawm rau lossis tshem tawm cov teeb liab tsis tseem ceeb.Lub dynamic ntau yam yuav tsum tau kho dawb do raws li kev kuaj mob.
Qhov tsim nyog dynamic ntau yam xaiv yuav tsum tsis tsuas yog xyuas kom meej cov zaub uas tsis tshua muaj thiab tsis muaj zog ncha teeb liab nyob rau hauv lub qhov txhab, tab sis kuj xyuas kom meej qhov tseem ceeb ntawm qhov chaw ntawm qhov txhab thiab muaj zog ncha.Qhov dav dav dav dav uas yuav tsum muaj rau kev kuaj mob plab plab yog 50 ~ 55dB.Txawm li cas los xij, txhawm rau ua tib zoo saib thiab saib xyuas cov ntaub so ntswg ntawm cov kab mob pathological, cov kab mob loj loj tuaj yeem raug xaiv thiab cov duab sib piv tuaj yeem raug txo kom txhawb cov ntaub ntawv kuaj mob pom hauv cov duab acoustic.
4. Kev hloov kho ntawm lub teeb pom kev muaj nuj nqi
Kev soj ntsuam tib neeg cov ntaub so ntswg nrog tsom acoustic beam tuaj yeem txhim kho qhov kev daws teeb meem ntawm ultrasound ntawm cov qauv zoo ntawm qhov chaw tsom (qhov txhab), thiab txo cov tiam ntawm ultrasonic artifacts, yog li txhim kho cov duab zoo.Tam sim no, ultrasonic tsom tsuas yog txais kev sib xyaw ua ke ntawm lub sijhawm tiag tiag dynamic electron tsom, hloov pauv aperture, acoustic lens thiab concave siv lead ua thev naus laus zis, kom qhov kev xav thiab txais tos ntawm ultrasonic tuaj yeem ua tiav ntau yam ntawm kev tsom mus rau qhov ze, nruab nrab thiab deb. teb.Rau qhov ntsuas ntsuas ultrasonic nrog kev ua haujlwm ntawm segmentalized tsom kev xaiv, qhov tob ntawm kev tsom tuaj yeem hloov kho los ntawm cov kws kho mob txhua lub sijhawm thaum lub sijhawm ua haujlwm.
