Gulu la zamankhwala la ultrasound probes

Akupanga kafukufuku (akupanga kafukufuku) ndi mbali yofunika kwambiri ya akupanga diagnostic chida.Sizingangosintha zizindikiro zamagetsi kukhala zizindikiro za ultrasound, komanso kusintha zizindikiro za ultrasound kukhala zizindikiro zamagetsi, ndiko kuti, zimakhala ndi ntchito ziwiri za ultrasound kufalitsa ndi kulandira.

Gulu la zamankhwala la ultrasound probes

Kapangidwe ndi mtundu wa kafukufuku wa ultrasound, komanso momwe zimakhalira pamayendedwe osangalatsa akunja, ntchito ndi malingaliro, zimakhala ndi ubale wabwino ndi mawonekedwe a mtengo wa ultrasound womwe umatulutsa, komanso kukhala ndi ubale wabwino ndi magwiridwe antchito, ntchito, ndi khalidwe la ultrasound diagnostic zida.The transducer element zakuthupi zilibe ubale wochepa ndi mawonekedwe a mtengo wa ultrasound;komabe, mphamvu ya piezoelectric, kuthamanga kwa mawu, kumveka kwa mawu ndi khalidwe la kulingalira la kutulutsa kwake ndi kulandilidwa ndizogwirizana kwambiri.

Pulse echo probe:

Kafufuzidwe kamodzi: Nthawi zambiri imasankha zida zadothi za piezoelectric pansi pa disc yopyapyala ngati transducer.Ultrasound yoyang'ana nthawi zambiri imagwiritsa ntchito njira ziwiri: chowonda chozungulira chozungulira kapena choboola pakati choboola ndi mbale choyang'ana kwambiri ndi mandala athyathyathya a disc-chibwenzi.Amagwiritsidwa ntchito mu A-mtundu, M-mtundu, makina zimakupiza jambulani ndi zimachitika Doppler akupanga diagnostic zida.

Kufufuza kwamakina: Chiwerengero cha tchipisi tamagetsi tapanikizidwa ndi njira yosuntha imatha kugawidwa m'mitundu iwiri: transducer unit reciprocating swing scanning ndi multi-element transducer rotching switching scanning probe.Kutengera ndi mawonekedwe a ndege yojambulira, imatha kugawidwa m'magawo, mawonekedwe owonera ma radial ndi kafukufuku wamakona apandege.

Electronic probe: Imatengera kapangidwe kazinthu zambiri ndipo imagwiritsa ntchito mfundo yamagetsi kuti ipange sikani yamtengo.Malinga ndi kapangidwe kake ndi mfundo yogwirira ntchito, imatha kugawidwa m'mizere yofananira, ma convex array ndi probe yapang'onopang'ono.

Kafukufuku wa intraoperative: Amagwiritsidwa ntchito kuwonetsa mawonekedwe amkati ndi malo a zida zopangira opaleshoni panthawi ya opaleshoni.Ndi kafukufuku wapamwamba kwambiri wokhala ndi pafupipafupi pafupifupi 7MHz.Zili ndi makhalidwe ang'onoang'ono komanso kusamvana kwakukulu.Ili ndi mitundu itatu: mtundu wa sikani wamakina, mtundu wa convex array ndi mtundu wowongolera waya.

Puncture probe: Imadutsa m'mitsempha yofananira, kupewa mpweya wa m'mapapo, mpweya wa m'mimba ndi minofu ya mafupa kuti ifike pafupi ndi minofu yakuya kuti iwunikidwe, ndikuwongolera kuzindikirika ndikusintha.Pakali pano pali ma probes a transrectal,

Transurethral probe, transvaginal probe, transesophageal probe, gastroscopic probe ndi laparoscopic probe.Ma probes awa ndi makina, oyendetsedwa ndi mawaya kapena mtundu wa convex;kukhala ndi ngodya zosiyanasiyana zooneka ngati fan;mtundu wa ndege imodzi ndi mitundu yambiri ya ndege.Ma frequency ndi okwera, nthawi zambiri pafupifupi 6MHz.M'zaka zaposachedwa, ma transvascular probe okhala ndi m'mimba mwake osakwana 2mm ndi ma frequency pamwamba pa 30MHz adapangidwanso.

Intracavitary probe: Imadutsa m'mitsempha yofanana ya thupi, kupeŵa mpweya wa m'mapapo, mpweya wa m'mimba ndi mafupa a mafupa kuti ayandikire pafupi ndi minyewa yakuya kuti awonedwe, kuwongolera kuzindikira ndi kuthetsa.Pakalipano, pali ma probes, transrectal probes, transvaginal probes, transesophageal probes, gastroscopic probes ndi laparoscopic probes.Ma probes awa ndi makina, oyendetsedwa ndi mawaya kapena mtundu wa convex;kukhala ndi ngodya zosiyanasiyana zooneka ngati fan;mtundu wa ndege imodzi ndi mitundu yambiri ya ndege.Ma frequency ndi okwera, nthawi zambiri pafupifupi 6MHz.M'zaka zaposachedwa, ma transvascular probe okhala ndi m'mimba mwake osakwana 2mm ndi ma frequency pamwamba pa 30MHz adapangidwanso.

Kufufuza kwa Doppler

Amagwiritsa ntchito kwambiri mphamvu ya Doppler kuyeza magawo akuyenda kwa magazi, komanso kuzindikira matenda amtima, komanso angagwiritsidwe ntchito powunika mwana wosabadwayo.Amagawidwa m'magulu atatu awa:

1. Kufufuza kosalekeza kwa Doppler: Zambiri mwa ma transmitter ndi tchipisi olandila zimapatulidwa.Pofuna kupanga kafukufuku wopitilira wa Doppler kukhala ndi chidwi chachikulu, nthawi zambiri palibe chipika choyamwa chomwe chimawonjezeredwa.Malinga ndi ntchito zosiyanasiyana, njira yolekanitsira chip yopatsira ndi cholandilira cha kafukufuku wopitilira wa Doppler ndizosiyana.

2. Pulse wave Doppler probe: Kapangidwe kake kamakhala kofanana ndi pulse echo probe, pogwiritsa ntchito chowotcha chopindika chimodzi, chokhala ndi wosanjikiza wofananira ndi chipika choyamwa.

3. Kufufuza kooneka ngati maula: Kapangidwe kake kamakhala ndi chipangizo chimodzi chokha chopatsirana, ndi tchipisi zisanu ndi chimodzi zolandirira mochizungulira, zokonzedwa mumpangidwe wa duwa la maula, zomwe zimagwiritsidwa ntchito poyang'ana mwana wosabadwayo ndikupeza kugunda kwa mtima wa fetal.
