Daim Ntawv Thov Kev Kho Mob Ultrasound Probe

Peb txhua tus paub tias qhov ntsuas ntsuas ntsuas ultrasonic tsim qhov xwm txheej ultrasonic tsis (hloov nthwv dej) thiab tau txais kev cuam tshuam ultrasonic tsis (echo tsis) los ntawm kev sojntsuam.Nws yog ib qho tseem ceeb ntawm cov cuab yeej kuaj mob, ib yam li lub qhov muag ntawm B-ultrasound tshuab, thiab nws tseem txuas nrog tib neeg lub cev thiab cov khoom siv.nruab nrab.

Lub luag haujlwm ntawm kev sojntsuam ultrasound yog hloov hluav taws xob teeb liab mus rau hauv ultrasonic signals los yog vice versa.Kev sojntsuam tuaj yeem xa thiab tau txais ultrasound, thiab ua haujlwm electro-acoustic thiab teeb liab hloov dua siab tshiab.Nws tuaj yeem hloov cov teeb liab hluav taws xob xa los ntawm tus tswv tsev mus rau hauv lub siab zaus oscillating ultrasonic teeb liab, thiab tseem tuaj yeem hloov cov teeb liab ultrasonic rov qab los ntawm cov ntaub so ntswg thiab cov kab mob hauv lub cev mus rau cov teeb liab hluav taws xob.nyob rau hauv lub monitor ntawm tus tswv tsev computer.Ultrasonic sojntsuam yog tsim los ntawm kev siv txoj haujlwm no.Hauv cov ntsiab lus dav dav, nws hloov pauv cov teeb liab hluav taws xob tawm los ntawm ultrasound rau hauv lub suab nrov zaus thiab xa nws los ntawm tib neeg lub cev, thiab tom qab ntawd hloov cov teeb liab cuam tshuam rau hauv hluav taws xob teeb liab thiab qhia nws ntawm tus tswv tsev, ib yam li whale.Lub ultrasonic zaus emissions nyob rau hauv dej hiav txwv zoo li puav judging qhov deb ntawm cov khoom los ntawm lub reflection ntawm lub suab tsis thaum hmo ntuj.

Daim Ntawv Thov Kev Kho Mob Ultrasound Probe

Lub wafer hauv qhov kev sojntsuam tuaj yeem tsim elastic deformation nyob rau hauv lub zog ntawm lub xeev, yog li tsim ultrasonic suab tsis;ntawm qhov tsis sib xws, thaum ultrasonic suab tsis dhau los ntawm lub wafer, nws kuj tuaj yeem ua rau elastic deformation, uas ua rau muaj kev hloov pauv voltage, thiab thaum kawg dhau los ntawm Lub Rooj Tswjhwm Saib cov teeb liab ua cov txheej txheem hluav taws xob hloov pauv kom tiav cov duab pom ntawm cov khoom kuaj pom. .Cov txheej txheem no yog hu ua piezoelectric effect (zoo thiab thim rov qab piezoelectric effect).

Daim ntawv thov ntawm kev sojntsuam ultrasound hauv ntau lub tuam tsev:

Daim ntawv thov ntawm convex array sojntsuam (3.5MHz) hauv obstetrics thiab gynecology thiab hepatobiliary, pancreas, spleen thiab raum

Kab array sojntsuam (3.5MHz) rau kev siv cov hlab ntsha thiab cov kabmob me
