Tlhahlobo ea bongaka ea ultrasound ke karolo ea bohlokoa ea sesebelisoa sa bongaka sa ultrasound.Molao-motheo oa eona o ka sehloohong ke ho sebelisa litšoaneleho tsa ho hasana le ho bonahatsa maqhubu a ultrasonic liseleng tsa motho ho fumana litšoantšo ka ho fetisetsa le ho amohela mesebetsi ea probe ho finyella tlhahlobo ea bongaka le phekolo.
Melao-motheo ea lipatlisiso tsa bongaka tsa ultrasound e ka aroloa ka lintlha tse latelang:
1. Phello ea Piezoelectric: Hangata lipatlisiso tsa ultrasound tsa bongaka li sebelisa lisebelisoa tsa piezoelectric, tse kang likristale tsa quartz, li-ceramics, joalo-joalo Ha li susumetsoa ke tšimo ea motlakase, lisebelisoa tsena li na le phello ea piezoelectric, ke hore, ho senyeha ha mechine.U sebelisa phello ena, thepa ea piezoelectric e ka sisinyeha ka ho tsosoa ha tšimo ea motlakase, kahoo e hlahisa maqhubu a ultrasonic.
2. Pulse wave emission: Medical ultrasound probe e hlahisa maqhubu a ultrasonic ka maqhubu a pulse.Ha thepa e thabisoa ke tšimo ea motlakase, e sisinyeha ka mochine, e hlahisa li-pulses tsa ultrasonic.Sebopeho sa pulse le maqhubu a vibrate li itšetlehile ka moralo oa probe le motlakase oa koloi.
3. Kamohelo ea maqhubu a Pulse: Ntle le ho fetisetsa maqhubu a ultrasonic, lisebelisoa tsa bongaka tsa ultrasound li boetse li sebelisoa ho amohela lipontšo tsa ultrasonic tse bonahatsang.Ha maqhubu a ultrasound a feta ka har'a lisele, a bonahatsoa ebe a hasana ho khutlela karolong e amohelang ea probe.Ntho e amohelang e fetola ho sisinyeha ha mochini hore e be lets'oao la tefo, ebe le fetoloa setšoantšo ka potoloho ea ts'ebetso ea matšoao.
4. Litšobotsi tsa mabala a molumo: Geometry le tlhophiso ea likarolo tsa ho fetisa le ho amohela tsa probe ea bongaka ea ultrasound e tla ama ka ho toba litšobotsi tsa molumo oa molumo.Lerata la molumo le bolela ho ajoa ha matla a matla a maqhubu a ultrasonic a hasang bohareng.Hangata li-probe tsa bongaka tsa ultrasound li sebelisa theknoloji e lebisang tlhokomelo ho ntlafatsa bokhoni ba ho tsepamisa mohopolo oa molumo oa molumo, ho fella ka litšoantšo tse hlakileng haholoanyane.
5. Phello ea Doppler: Lisebelisoa tsa bongaka tsa ultrasound li ka boela tsa sebelisa phello ea Doppler ho lekanya lebelo le tataiso ea maro.Ha maqhubu a ultrasonic a kopana le motsamao oa mokelikeli, phetoho ea maqhubu e etsahala, e lekanang le lebelo la mokelikeli.Ka ho lekanya boholo le tataiso ea li-frequency shifts, ho ka fumanoa tlhahisoleseling mabapi le motsamao oa mokelikeli.
