Nigute ushobora kunoza amashusho ya Ultrasound (2)

Nkuko twese tubizi ko kumvikana kwishusho ya ultrasound bigena niba isuzuma ryacu ari ukuri, Usibye imikorere yimashini, mubyukuri dufite ubundi buryo bwo kunoza neza ishusho.

Usibye ibyo twavuze mu ngingo ibanziriza iyi, ibintu bikurikira bizagira ingaruka kumashusho ya ultrasound.

1. Icyemezo

Hariho imyanzuro itatu yingenzi ya ultrasound: gukemura umwanya, gukemura igihe, no gukemura itandukaniro.

Resolution Igisubizo

Umwanya uhoraho nubushobozi bwa ultrasound gutandukanya ingingo ebyiri mubwimbitse bwihariye, bigabanijwe muburyo bwa axial hamwe no gukemura kuruhande.

Imyifatire ya Axial nubushobozi bwo gutandukanya ingingo ebyiri mucyerekezo kibangikanye na ultrasound beam (longitudinal), kandi iringaniza na transducer inshuro.

Imyitozo ya axial ya high-frequency probe ni ndende, ariko mugihe kimwe, kwiyegeranya kwijwi ryamajwi muri tissue nabyo ni binini, bizavamo igisubizo kinini cyo hejuru cyimiterere yimiterere idahwitse, mugihe icyerekezo cya axial cyimbitse imiterere ni mike cyane, ndashaka rero kunoza Axial reaction yuburyo bwimbitse, haba mukuzana transducers yumurongo mwinshi hafi yintego (urugero, transesophageal echocardiography) cyangwa muguhindura transducers nkeya.Niyo mpanvu birasabwa gukoresha progaramu yumurongo mwinshi kuri ultrasound ya tissue superficial na probe nkeya kuri ultrasound yimbitse.

Gukemura kuruhande nubushobozi bwo gutandukanya ingingo ebyiri perpendicular yerekeza kumurongo wa ultrasonic beam (horizontal).Usibye kuba ugereranije ninshuro ziperereza, bifitanye isano rya bugufi no gushiraho icyerekezo.Ubugari bwibiti bya ultrasonic nicyo kigufi cyane mu gice cyibandwaho, bityo impande zombi zikaba nziza kuri kwibanda.Hejuru turashobora kubona ko inshuro hamwe nibitekerezo bya probe bifitanye isano rya bugufi no gukemura umwanya wa ultrasound.1

Igishushanyo 1

Resolution Gukemura by'agateganyo

Gukemura by'agateganyo, bizwi kandi nk'ikigero cy'ikadiri, bivuga umubare w'amakadiri ku isegonda yo gufata amashusho.Ultrasound yandura muburyo bwa pulses, kandi impyisi ikurikira irashobora kwanduzwa gusa nyuma yimpanuka zabanjirije kugaruka kuri ultrasound.

Igihe cyo gukemura gifitanye isano nuburebure n'umubare w'ibyerekezo.Nubujyakuzimu nubunini bwibanze, niko hasi ya pulse yisubiramo inshuro nyinshi nigipimo cyikigero.Buhoro buhoro amashusho, amakuru make yafashwe mugihe gito.Mubisanzwe iyo igipimo kiri munsi ya 24 frame / s, ishusho iranyeganyega.

Mugihe cyo gukora anesthesia yubuvuzi, iyo urushinge rwihuta cyangwa ibiyobyabwenge byatewe vuba, igipimo gito cyo hasi kizatera amashusho atagaragara, bityo gukemura byigihe gito ningirakamaro cyane muburyo bwo kubona urushinge mugihe cyo gutobora.

Gukemura itandukaniro bivuga itandukaniro ritoya ryikigereranyo igikoresho gishobora gutandukanya.Urwego rudasanzwe rufitanye isano rya bugufi no gukemura, uko urwego rugenda rwiyongera, niko rutandukanya itandukaniro, ishusho yoroshye, kandi nubushobozi bwo kumenya ibice bibiri cyangwa ibintu bisa (Ishusho 2).

Igishushanyo 2

Inshuro

Inshuro ihwanye neza nuburyo bwo gutandukanya umwanya kandi bigereranywa no kwinjira muri ultrasound (Ishusho 3).Umuvuduko mwinshi, uburebure buke, kwiyegereza kwinshi, kwinjirira nabi, hamwe no gukemura neza.

Igishushanyo 3

Mubikorwa byubuvuzi, intego yibikorwa byinshi birasa nkaho bitagaragara, bityo rero umurongo munini wumurongo wumurongo urashobora guhuza ibyifuzo byabaganga bya buri munsi, ariko mugihe uhuye nabarwayi bafite umubyibuho ukabije cyangwa intego zikomeye (nka lumbar plexus), umurongo muto wa convex array iperereza naryo ni ngombwa.

Ibyinshi mubikorwa bya ultrasonic bigezweho ni Broadband, niyo shingiro ryo kumenya tekinoroji yo guhinduranya.Guhindura inshuro bisobanura ko inshuro zakazi ziperereza zishobora guhinduka mugihe ukoresheje iperereza rimwe.Niba intego iri hejuru, hitamo inshuro nyinshi;niba intego ari ndende, hitamo inshuro nke.

Dufashe urugero rwa ultrases ya Sonosite, guhinduka kwayo inshuro 3 bifite uburyo 3, aribwo Res (imyanzuro, izatanga igisubizo cyiza), Gen (rusange, izatanga impirimbanyi nziza hagati yo gukemura no kwinjira), Ikaramu (penetration, izatanga kwinjira neza ).Kubwibyo, mubikorwa nyirizina, bigomba guhinduka ukurikije ubujyakuzimu bw'ahantu hagenewe.
