Classification yezvokurapa ultrasound probes

Ultrasonic probe (ultrasonic probe) chinhu chakakosha chikamu cheiyo ultrasonic diagnostic chiridzwa.Haikwanise kungoshandura zviratidzo zvemagetsi kuita zviratidzo zve ultrasound, asiwo kushandura zviratidzo zve ultrasound kuva zviratidzo zvemagetsi, kureva kuti, ine mabasa maviri ekufambisa kwe ultrasound uye kugamuchira.

Classification yezvokurapa ultrasound probes

Chimiro uye rudzi rweiyo ultrasound probe, pamwe nemamiriro ekunze ekuwedzera pulse parameters, basa uye yekutarisa maitiro, ane hukama hukuru nechimiro cheiyo ultrasound beam iyo inoburitsa, uye zvakare vane hukama hukuru nekuita, basa, uye kunaka kweiyo ultrasound diagnostic apparatus.Iyo transducer element zvinhu ine hukama hudiki nechimiro cheiyo ultrasound beam;zvisinei, iyo piezoelectric kunyatsoita, kurira kwenzwi, kusimba kwenzwi uye yekufungidzira kunaka kwekubuda kwayo uye kugamuchirwa kune hukama.

Pulse echo probe:

Single probe: Kazhinji inosarudza piezoelectric ceramics pasi kuita flat thin disc se transducer.Ultrasound inotarisa kazhinji inotora nzira mbiri: ganda rakatetepa rakatenderera kana mbiya-yakaita transducer inoshanda yakatarisa uye flat thin disc sound-dating lens inotarisa.Inowanzo shandiswa muA-mhando, M-mhando, mechanical fan scan uye pulse Doppler ultrasonic diagnostic equipment.

Mechanical probe: Huwandu hweakatsikirirwa emagetsi machipisi uye mafambiro ekufamba anogona kukamurwa kuita mhando mbiri: unit transducer inodzokorodza swing scanning uye multi-element transducer inotenderera switching scanning probe.Zvinoenderana nehunhu hweiyo scan musiyano ndege, inogona kukamurwa kuita chikamu scan, panoramic radial scan uye rectangular ndege linear scan probe.

Electronic probe: Inotora chimiro che-multi-element uye inoshandisa musimboti wemagetsi kuita ruzha rwekuvheneka.Zvinoenderana nechimiro uye musimboti wekushanda, inogona kukamurwa kuita mutsara array, convex array uye phased array probe.

Intraoperative probe: Inoshandiswa kuratidza chimiro chemukati uye chinzvimbo chemidziyo yekuvhiya panguva yekushanda.Iyo yakakwira-frequency probe ine frequency inosvika 7MHz.Iine maitiro ehukuru hudiki uye kugadziriswa kwepamusoro.Iyo ine marudzi matatu: mechanical scanning type, convex array type uye wire control type.

Puncture probe: Iyo inopfuura nepakati inoenderana nemuviri mhango, ichidzivirira gasi remapapu, gasi remudumbu uye bhonzo tishu kuti iswedere pedyo nematishu yakadzika kuti iongororwe, ichivandudza kuonekwa uye kugadzirisa.Parizvino pane transrectal probes,

Transurethral probe, transvaginal probe, transesophageal probe, gastroscopic probe uye laparoscopic probe.Aya maprobe ndeemakanika, waya-inodzorwa kana convex array mhando;vane makona akasiyana-akaita fan;imwe-ndege mhando uye akawanda-ndege mhando.Iyo frequency yakanyanya kukwirira, kazhinji kutenderera 6MHz.Mumakore achangopfuura, transvascular probes ane dhayamita isingasviki 2mm uye frequency pamusoro pe30MHz zvakare akagadzirwa.

Intracavitary probe: Inopfuura nepakati inoenderana nemuviri mhango, ichidzivirira gasi remapapu, gasi remudumbu uye mapfupa emapfupa kuti aswedere pedyo nematishu akadzika kuti aongororwe, achivandudza kuonekwa uye kugadzirisa.Parizvino, kune transrectal probes, transurethral probes, transvaginal probes, transesophageal probes, gastroscopic probes uye laparoscopic probes.Aya maprobe ndeemakanika, waya-inodzorwa kana convex array mhando;vane makona akasiyana-akaita fan;imwe-ndege mhando uye akawanda-ndege mhando.Iyo frequency yakanyanya kukwirira, kazhinji kutenderera 6MHz.Mumakore achangopfuura, transvascular probes ane dhayamita isingasviki 2mm uye frequency pamusoro pe30MHz zvakare akagadzirwa.

Doppler probe

Inonyanya kushandisa iyo Doppler mhedzisiro kuyera kuyerera kweropa paramita, pamwe nekuongororwa kwechirwere chemoyo, uye inogona zvakare kushandiswa pakuongorora kwe fetus.Zvikuru zvakakamurwa kuva marudzi matatu anotevera:

1. Inoenderera mberi wave Doppler probe: Mazhinji eanotumira uye anogamuchira machipisi akaparadzaniswa.Kuti uite iyo inoenderera wave Doppler probe ine yakanyanya kunzwa, kazhinji hapana chivharo chekunyura chinowedzerwa.Zvinoenderana nekushandiswa kwakasiyana, nzira yekuparadzanisa chip yekuparadzira uye yekugamuchira chip yeinoenderera mberi wave Doppler probe zvakare yakasiyana.

2. Pulse wave Doppler probe: Chimiro chacho chinowanzofanana nepulse echo probe, uchishandisa imwechete-pressure wafer, ine jira rinoenderana uye chivharo chekunyura.

3. Plum-shaped probe: Chimiro chayo chiri pakati nepane transmitting chip chimwe chete, uye matanhatu anotambira machipisi akaitenderedza, akarongwa muchimiro chepramu maruva, anoshandiswa kutarisa chibereko uye kuwana kurova kwemoyo we "fetus".
