Cov duab kho mob ib txwm siv los kuaj xyuas, saib xyuas lossis kho qee yam kab mob, tau tawm tsam ntev kom tau txais cov duab meej ntawm cov neeg mob tawv nqaij, cov kws tshaj lij hais.
Cov kws tshawb fawb tau tshaj tawm tias lawv tau tshawb pom ib txoj hauv kev los txhim kho cov duab kho mob, tso cai rau cov kws kho mob saib xyuas sab hauv lub cev, tsis hais cov xim ntawm daim tawv nqaij.
Qhov kev tshawb pom tshiab tshaj plaws tau tshaj tawm nyob rau lub Kaum Hlis qhov teeb meem ntawm phau ntawv xov xwm Photoacoustics. Ib pawg ntawm cov kws tshawb fawb tau ua qhov kev ntsuam xyuas ntawm lub hauv pliaj ntawm 18 tus neeg tuaj yeem pab dawb, suav nrog cov tib neeg uas muaj cov xim tawv nqaij. Lawv qhov kev tshawb pom tau qhia txog kev sib raug zoo ntawm qib ntawm kev sib tsoo, kev cuam tshuam ntawm cov teeb liab photoacoustic cuam tshuam rau qhov pom tseeb ntawm kev duab, thiab qhov tsaus ntuj ntawm daim tawv nqaij.
"Daim tawv nqaij tseem ceeb ua haujlwm raws li lub suab xa tawm, tab sis nws tsis xa tib hom suab tsom pom hauv ultrasound. Hloov chaw, lub suab tau nthuav dav thoob plaws thiab ua rau muaj kev ntxhov siab ntau," Bell hais. "Yog li ntawd, qhov tawg ntawm lub suab vim kev nqus melanin ua teeb meem ntau ntxiv thaum melanin concentration nce."
Hloov cov txheej txheem
Kev tshawb fawb, ua nrog kev koom tes nrog cov kws tshawb fawb Brazilian uas muaj kev paub dhau los nrog ib qho ntawm Bell's algorithms, qhia tias lub teeb liab-rau- suab nrov piv, ib qho kev ntsuas kev tshawb fawb rau kev sib piv cov teeb liab lub zog rau cov suab nrov tom qab, tau txhim kho thoob plaws txhua lub suab nrov thaum cov kws tshawb fawb siv ib txoj hauv kev hu ua "short-lag spatial coherence beamaging." Cov txheej txheem no, pib tsim los rau kev kuaj xyuas ultrasound, muaj peev xwm hloov tau rau kev siv hauv photoacoustic imaging.
Txoj kev sib txuas ob qho tib si lub teeb thiab ultrasound thev naus laus zis los tsim cov kev kho mob tshiab, raws li tau piav qhia los ntawm Theo Pavan, uas cuam tshuam nrog lub tuam tsev physics ntawm University of São Paulo hauv Brazil. Raws li Pavan, lawv cov kev tshawb fawb tau lees paub tias cov txheej txheem tshiab no tsis tshua muaj kev cuam tshuam los ntawm cov xim ntawm cov tawv nqaij, ua rau cov duab zoo dua piv rau cov qauv siv dav siv hauv thaj chaw.
Cov kws tshawb fawb tau sau tseg tias lawv txoj kev tshawb fawb yog thawj zaug los ua lub hom phiaj kev soj ntsuam ntawm cov tawv nqaij thiab muab ob qho tib si zoo thiab muaj pov thawj qhia tias daim tawv nqaij photoacoustic teeb liab thiab clutter artifacts yog amplified raws li cov epidermal melanin cov ntsiab lus nce.
Kev rov xav dua tshiab hauv kev kho mob
Cov kws tshawb fawb cov kev tshawb pom yuav muaj qhov cuam tshuam loj rau kev txhawb nqa kev ncaj ncees hauv kev kho mob ntawm qhov dav dav.Dr. Camara Jones, kws kho mob hauv tsev neeg, kws kho mob kis mob, thiab yav dhau los tus thawj tswj hwm ntawm American Public Health Association, uas tsis koom nrog hauv txoj kev tshawb no, tau hais txog kev tsis ncaj ncees hauv kev tshawb fawb thev naus laus zis hauv kev pom zoo ntawm cov khoom uas muaj txiaj ntsig zoo rau cov tib neeg nrog cov tawv nqaij sib zog. Nws tau taw qhia txog qhov tsis muaj caj ces rau kev sib txawv ntawm haiv neeg hauv tib neeg genome ua pov thawj los txhawb qhov kev lees paub no. Cov kev tshawb fawb ua ntej kuj tau txheeb xyuas cov tawv nqaij tsis zoo hauv kev kho mob thev naus laus zis, nrog kev tshawb pom qhia tias cov cuab yeej kho mob uas siv infrared sensing yuav tsis ua tau zoo ntawm cov tawv nqaij tsaus vim muaj peev xwm cuam tshuam nrog lub teeb pom kev.
Tswb qhia qhov kev cia siab tias nws txoj kev tshawb fawb tuaj yeem qhib qhov rooj rau kev tshem tawm kev tsis ncaj ncees hauv kev kho mob thiab txhawb lwm tus los tsim cov cuab yeej siv uas muaj txiaj ntsig rau txhua tus neeg, tsis hais lawv cov xim ntawm daim tawv nqaij.
"Kuv ntseeg tias muaj peev xwm qhia tau tias peb tuaj yeem tsim thiab tsim thev naus laus zis - uas tsis yog ua haujlwm rau ib pawg me me ntawm cov pej xeem tab sis ua haujlwm rau ntau haiv neeg. Qhov no yog kev tshoov siab rau tsis yog kuv pab pawg xwb, tab sis rau cov pab pawg thoob ntiaj teb pib xav txog qhov kev taw qhia no thaum tsim thev naus laus zis. Nws puas ua haujlwm rau cov pej xeem dav dua?" Tswb hais tias.

Raws li peb txhua tus paub, kev txhim kho ntawm kev kho mob kev lag luam yog sib cais los ntawm kev txhim kho cov khoom siv kho mob - tus neeg sawv cev sib txawv thiab lawv cov khoom siv txhawb nqa - uas tau siv dav hauv daim teb no. Nyob rau hauv Suav teb, uas yog nto moo rau nws kev lag luam kev lag luam, muaj ntau manufacturers nto moo nyob rau hauv tsev thiab txawv teb chaws rau zus tau tej cov khoom kho mob, xws liLnkMed. Txij li thaum nws tsim, LnkMed tau tsom mus rau thaj tsam ntawm cov neeg ua haujlwm siab sib txawv ntawm cov tshuaj txhaj tshuaj. LnkMed pawg engineering yog coj los ntawm Ph.D. nrog ntau tshaj kaum xyoo ntawm kev paub thiab tau koom nrog kev tshawb fawb thiab kev loj hlob. Nyob rau hauv nws kev taw qhia, lubCT ib lub taub hau injector,CT ob lub taub hau injector,MRI contrast tus neeg sawv cev injector, thiabAngiography high-pressure contrast agent injectoryog tsim los nrog cov yam ntxwv no: lub cev muaj zog thiab compact, yooj yim thiab ntse ua haujlwm interface, ua tiav kev ua haujlwm, muaj kev nyab xeeb siab, thiab tsim qauv ruaj khov. Peb kuj tseem tuaj yeem muab cov koob txhaj tshuaj thiab cov raj uas sib haum nrog cov npe nrov ntawm CT, MRI, DSA txhaj tshuaj Nrog lawv tus cwj pwm ncaj ncees thiab lub zog ua haujlwm, txhua tus neeg ua haujlwm ntawm LnkMed thov caw koj tuaj thiab tshawb nrhiav ntau lub lag luam ua ke.
