Mefuta e meraro e atileng haholo ea li-probe (tseo hape li bitsoang ultrasonic transducers) ke linear, convex, le phased array.Qeto e haufi le lebala e ntle ebile e ka sebelisoa bakeng sa tlhahlobo ea methapo ea mali.Sebaka sa convex se loketse tlhahlobo e tebileng, e ka sebelisetsoang tlhahlobo ea mpa joalo-joalo.Sehlopha sa mekhahlelo se na le sebaka se senyenyane sa maoto le maqhubu a tlaase, a ka sebelisetsoang liteko tsa pelo, joalo-joalo.
Sensor ea mola
Likristale tsa piezoelectric li hlophisitsoe ka tatellano, sebopeho sa sefate se khutlonnetsepa, 'me qeto e haufi-ufi e ntle.
Taba ea bobeli, khafetsa le ts'ebeliso ea li-transducers tsa linear li ipapisitse le hore na sehlahisoa se sebelisoa bakeng sa litšoantšo tsa 2D kapa 3D.Li-transducer tsa linear tse sebelisetsoang ho nka litšoantšo tsa 2D li tsepamisitsoe ho 2.5Mhz - 12Mhz.
U ka sebelisa sensor ena bakeng sa lits'ebetso tse fapaneng tse kang: tlhahlobo ea vascular, venipuncture, vascular visualization, thoracic, thyroid, tendon, arthogenic, intraoperative, laparoscopic, imaging photoacoustic, ultrasound velocity change imaging.
Li-transducer tsa linear bakeng sa litšoantšo tsa 3D li na le maqhubu a bohareng a 7.5Mhz - 11Mhz.
U ka sebelisa converter ena: sefuba, qoqotho, vascular kopo carotid.
Sensor ea convex
Qeto ea setšoantšo sa convex e ea fokotseha ha botebo bo ntse bo eketseha, 'me khafetsa le ts'ebeliso ea eona e ipapisitse le hore na sehlahisoa se sebelisoa bakeng sa litšoantšo tsa 2D kapa 3D.
Ka mohlala, li-convex transducers bakeng sa litšoantšo tsa 2D li na le maqhubu a bohareng a 2.5MHz - 7.5MHz.U ka e sebelisa bakeng sa: litlhahlobo tsa mpa, litlhahlobo tsa transvaginal le transrectal, tlhahlobo ea litho.
Transducer ea convex bakeng sa litšoantšo tsa 3D e na le sebaka se pharaletseng sa pono le maqhubu a bohareng a 3.5MHz-6.5MHz.U ka e sebelisa bakeng sa litlhahlobo tsa mpa.
Sensor ea Phased Array
Transducer ena, e reheletsoeng ka tlhophiso ea likristale tsa piezoelectric, tse bitsoang phased array, ke kristale e sebelisoang haholo.Sebaka sa eona sa marang-rang se moqotetsane empa se atoloha ho latela makhetlo a kopo.Ho feta moo, sebopeho sa beam se batla se le kgutlotharo mme tharollo e haufi le lebala ha e ntle.
Re ka e sebelisa bakeng sa: litlhahlobo tsa pelo, ho kenyeletsoa litlhahlobo tsa transesophageal, litlhahlobo tsa mpa, litlhahlobo tsa boko.
