Kev faib tawm thiab siv cov txuj ci ntawm kev sojntsuam ultrasound
Kev sojntsuam yog qhov tseem ceeb tshaj plaws ntawm B-ultrasound tshuab. Ultrasound sojntsuam tuaj yeem raug cais los ntawm ntau yam sib txawv hauv qab no
1. Raws li kev kuaj mob ib feem, muaj ophthalmic probes, lub plawv probes, plab probes, cranial probes, intracavitary probes, thiab lwm yam.;
2. Muab faib los ntawm txoj kev thov, muaj cov tshuaj tiv thaiv kabmob kheesxaws, kev sojntsuam intracorporeal, thiab kev sojntsuam biopsy;
3. Raws li tus naj npawb ntawm cov khoom vibration siv nyob rau hauv lub transducer nyob rau hauv lub sojntsuam, muaj ib chav tsev probes thiab multi-element probes;
Hauv cov txheej txheem tshuaj xyuas ultrasonic, kev sib kis thiab kev txais tos ntawm ultrasonic tsis tau pom los ntawm kev sojntsuam. Kev ua tau zoo ntawm kev sojntsuam ncaj qha cuam tshuam rau cov yam ntxwv ntawm ultrasound thiab cov duab ntawm ultrasound. Feem ntau siv ultrasound probes muaj xws li phased array probes, convex array probes thiab linear array probes.
(1) Phaseed array sojntsuam muaj qhov chaw me me ntawm qhov chaw sojntsuam, uas ua rau nws yooj yim rau scan tag nrho lub plawv los ntawm qhov chaw intercostal. Feem ntau, qhov zaus qis dua, thiab qhov zaus ntawm cov menyuam yaus theem array sojntsuam yog siab dua me ntsis. Feem ntau yog siv rau lub plawv scan, intracranial hlab ntsha scan thiab lub ntsws ultrasound scan, thiab lwm yam.
(2) Lub convex array sojntsuam muaj thaj tsam loj, uas yog ib qho yooj yim los soj ntsuam ntau yam kabmob thiab qhov chaw hauv plab kab noj hniav. Feem ntau, qhov zaus yog tsawg. Lub convex array sojntsuam rau cov menyuam yaus yog siab dua me ntsis, tab sis qhov chaw ntawm qhov kev sojntsuam yog me dua. Feem ntau yog siv rau kev kuaj mob plab thiab plab hauv plab, FAST scans, pleural effusion scans, thiab kuaj lub ntsws ultrasound.
(3) Linear array probe Qhov kev sojntsuam nto qhov chaw sib txawv, muaj qhov loj thiab me. Feem ntau, qhov zaus kuj yog siab heev, yog li cov kev ntsuam xyuas tseem ceeb yog musculoskeletal, cov hlab ntsha, cov khoom nruab nrog cev thiab cov ntaub so ntswg thiab lwm qhov chaw. Nrog rau kev siv ntau ntawm ultrasound hauv kev kho mob, tshwj xeeb tshaj yog kev siv plaub-dimensional ultrasound, 4D probes tau dhau los ua neeg nyiam.
Cov txheej txheem ntawm B-ultrasound sojntsuam
Rau cov neeg pib tshiab, vim li cas vim li cas ultrasound nyuaj yog qhov tseem ceeb hauv kev siv cov tshuaj ntsuam xyuas. Piv txwv li, tuav qhov kev sojntsuam ntev ntev ua rau mob ntawm lub dab teg thiab caj npab; daim duab tsis meej; lub resulting duab ploj tam sim ntawd thiab hais txog.
1. Tilt, txoj hauj lwm ntawm cov hlab ntsha thaiv kev sojntsuam ntawm ib sab ntawm lub thoracic qaum. Nyob rau lub sijhawm no, yog tias tus Tsov tus tw ntawm qhov kev sojntsuam muaj kev ntxhov siab me ntsis, daim duab ultrasound yuav tsis pom cov ribbed transverse ligament seem ntawm qhov chaw paravertebral, tab sis qhov ntev axis ntawm cov tav. Yog li ntawd, thaum scanning ntau theem, peb yuav tsum paub siv cov txheej txheem ntawm qaij.
2. Tig: Tig, txoj hauj lwm ntawm cov hlab ntsha thaiv kev sojntsuam ntawm ib sab ntawm tus txha caj qaum. Lub sijhawm no, qhov kev sojntsuam qhia qhov ntev-axis saib ntawm cov txheej txheem transverse ntawm ribbed transverse txheej txheem ligament. Yog hais tias qhov kev sojntsuam yog tig 90 degrees nyob rau lub sijhawm no, ob peb qhov luv-axis views ntawm cov txheej txheem transverse lossis tav tuaj yeem pom. Yog li ntawd, thaum luam theej duab, yog tias koj xav hloov ntawm qhov ntev axis thiab luv axis (xws li lub axis ntev ntawm cov hlab ntsha, lub axis luv), los yog thaum koj xav tau cov ces kaum sib txawv (xws li lub apical 2-chamber. saib, apical ntev axis saib) Hloov), koj tuaj yeem tig qhov kev sojntsuam.
3. Align: pob taws ntiv taw, kuj yog txoj hauj lwm ntawm cov hlab ntsha thaiv kev sojntsuam ntawm ib sab ntawm tus txha caj qaum. Qhov kev sojntsuam txav tawm mus rau qhov sib npaug ntawm cov tav los qhia qhov ntev-axis saib ntawm cov tav deb ntawm lub vertebral disc. Yog li ntawd, yog tias koj xav taug qab cov hlab ntsha, cov hlab ntsha, cov hlab ntsha, cov hlab ntsha lossis cov leeg thaum lub sijhawm kuaj ultrasound (tam sim no muaj cov cuab yeej zoo dua li LogiQView, uas tuaj yeem siv Align sojntsuam txhawm rau txhawm rau txhawm rau txhawm rau loj dua lossis ntev dua kom tau txais cov duab tiav), Koj tuaj yeem ua qhov Align soj ntsuam txav.
4. Xovxwm: Xovxwm, kuaj mob plab plab. Yog tias daim duab ultrasound tsis zoo vim yog daim ntawv thov lotus tsawg, koj tuaj yeem nias qhov kev sojntsuam kom qhov kev sojntsuam tiv tauj ntawm daim tawv nqaij kom zoo dua, kom lub ultrasound tuaj yeem hla tau zoo thiab tau txais cov duab zoo dua. Kev siv thev naus laus zis, elastography yog tam sim no muaj, thiab qhov softness thiab hardness ntawm cov huab hwm coj tuaj yeem nkag siab tau los ntawm nias qhov kev sojntsuam tsis tu ncua.
Thaum siv ib qho kev sojntsuam ultrasound, nws muaj lwm qhov tseem ceeb heev, uas yog, txawm tias qhov scan nyob qhov twg, tus neeg teb xov tooj yuav tsum muaj qhov fulcrum ntawm tus neeg mob' daim tawv nqaij kom ntseeg tau tias thaum muaj cov duab zoo tshwm, nws yuav tsis yooj yim khawb.
