Ultrasound probes ndi gawo lalikulu la machitidwe a ultrasound.
Ntchito yake yofunikira kwambiri ndikukwaniritsa kutembenuka kwapakati pakati pa mphamvu yamagetsi ndi mphamvu yamayimbidwe, ndiko kuti, imatha kusintha mphamvu zonse zamagetsi kukhala mphamvu yamamvekedwe ndi mphamvu yamamvekedwe kukhala mphamvu yamagetsi.Chinthu chofunika kwambiri chomwe chimamaliza kusintha kumeneku ndi Piezoelectric crystal.Krustalo yemweyo amadulidwa ndendende mu chinthu chimodzi (Element) ndikukonzedwa kuti akhale mawonekedwe a geometric.
Chofufuzacho chikhoza kukhala ndi zinthu zochepa monga makumi komanso zikwi makumi amitundu yosiyanasiyana.Gulu lililonse lili ndi mayunitsi 1 mpaka 3.
Pofuna kusangalatsa zinthu zambiri kuti apange mafunde akupanga ndikutenga ma akupanga magetsi, mawaya ayenera kuwotcherera ku gulu lililonse lazinthu zingapo.
Ngati agwiritsidwa ntchito molakwika, ma solder amatha kuwonongeka mosavuta ndi couplant yolowera kapena kuthyoledwa ndi kugwedezeka kwakukulu.
Kuti atsogolere akupanga mtengo mu kafukufuku bwino, ndi lamayimbidwe Impedans (mlingo wa chotchinga kwa akupanga yoweyula) pa njira ya akukwiyitsa mtengo ayenera kusinthidwa kwa mlingo womwewo monga khungu la munthu - pamaso unyinji wa zinthu. , onjezani zigawo zingapo za zinthu zophatikizika.Chigawo ichi ndi chomwe timachitcha kuti chofanana.Cholinga cha izi ndikuwonetsetsa kuti mulingo wapamwamba kwambiri wa kujambula kwa ultrasound ndikuchotsa zinthu zakale zomwe zimayambitsidwa ndi kuchuluka kwa impedance.Tangowona kumene kuchokera mu chithunzi cha probe kuti gawo lakunja la kafukufukuyo lili ndi dzina lachilendo la Lens.Ngati mukuganiza za lens ya kamera, mukulondola!
Ngakhale si galasi, wosanjikiza uwu ndi wofanana ndi galasi lagalasi la mtengo wa ultrasound (womwe ukhoza kufananizidwa ndi mtengo) ndipo umagwiranso ntchito mofananamo-kuthandizira ultrasound mtengo kuyang'ana.The element ndi lens layer zimatsatiridwa kwambiri.Pasakhale fumbi kapena zonyansa.Osatchulanso za mpweya.Izi zikusonyeza kuti kafukufuku amene timagwira m'manja mwathu tsiku lonse ndi chinthu chofewa komanso chosakhwima!Chitani mofatsa.Zosanjikiza zofananira ndi ma lens ndizosiyana kwambiri ndi izi.Sikoyenera kungopeza zomata za rabala.Pomaliza, kuti kafukufukuyo agwire ntchito mokhazikika komanso kosatha, ayenera kusungidwa m'malo otsekedwa.Tulutsani mawaya ndikulumikiza ku socket.Monga momwe kafukufukuyu timagwirira m'manja mwathu ndikuzigwiritsa ntchito tsiku lililonse.
Chabwino, tsopano popeza tili ndi chidziwitso choyambirira cha kafukufukuyu, pogwiritsira ntchito tsiku ndi tsiku timayesa kupanga chizolowezi chabwino cha kumukonda.Tikufuna kuti ikhale ndi moyo wautali, wogwira mtima kwambiri, ndi zolephera zochepa.Mwachidule, tigwire ntchito.Ndiye, kodi tiyenera kulabadira chiyani tsiku lililonse?Gwirani mopepuka, osagunda, osagunda waya, osapinda, osasunthika Kuzizira ngati sikunagwiritsidwe ntchito M'malo oundana, wolandirayo amazimitsa voteji yayikulu kupita kuzinthu zingapo.Chipangizo cha kristalo sichimazunguliranso ndipo kafukufukuyo amasiya kugwira ntchito.Chizolowezichi chikhoza kuchedwetsa ukalamba wa kristalo unit ndikuwonjezera moyo wa kafukufuku.Maundani kafukufukuyo musanalowe m'malo mwake.Tsekani kafukufukuyo pang'onopang'ono osasiya couplant.Musagwiritse ntchito probe, pukutani couplant.Pewani kutayikira, zinthu za dzimbiri ndi ma solder.Chisamaliro chiyenera kutengedwa popha tizilombo Mankhwala monga mankhwala ophera tizilombo toyambitsa matenda ndi zoyeretsera zimatha kuyambitsa magalasi ndi kutsogoza ma sheafu a mphira kukalamba ndi kukhala osalimba.Mukamiza ndikupha tizilombo toyambitsa matenda, pewani kukhudzana pakati pa soketi ya probe ndi mankhwala ophera tizilombo.
