Guhindura ibikoresho byo gusuzuma ultrasonic

Gukemura ikibazo cya ultrasonic imaging igikoresho cyo gusuzuma

Kwerekana amashusho ya Ultrasonic byakoreshejwe cyane mugupima kubaga, umutima-mitsi, oncologiya, gastroenterology, amaso, ubuvuzi, kubyara nizindi ndwara.Mu myaka yashize, kuruhande rumwe, iterambere ryibikoresho byo gusuzuma ultrasonic yerekana amashusho bihora bisuzuma ivuriro ryibikorwa bishya, kurundi ruhande nkamashusho ya ultrasound mugupima uburambe no gusobanukirwa imikorere yibikoresho byerekana amashusho ya ultrasonic, abaganga nibikorwa mubwiza bwibikoresho byo kwisuzumisha ultrasonic kandi akenshi bigashyira ahagaragara ibyifuzo bitandukanye hamwe nibyifuzo, kugirango bidateza imbere gusa urwego rwo gusuzuma indwara ya ultrasonography byiyongera bidasubirwaho, Byongeye kandi, ikoreshwa ryamashusho ya ultrasonic ryarushijeho kwiyongera, kandi tekinoroji yo gusuzuma amashusho ya ultrasonic yatejwe imbere .

1. Gukurikirana ikibazo

Kugirango ubone ishusho nziza yo gusuzuma agaciro, ibintu bitandukanye birakenewe.Muri byo, gukemura ikibazo cya ultrasonic ibikoresho byo gusuzuma ni ngombwa cyane.Nyuma yo kwakira no kugenzura bimaze gukoreshwa, ishusho yambere irerekanwa kuri ecran.Reba niba ibara ryijimye ryuzuye mbere yo gukemura, hanyuma ushyire nyuma yo gutunganya muburyo bumwe.Itandukaniro na Lright ya monitor irashobora guhinduka nkuko ubyifuza.Kuramo monite kugirango ikorwe neza, niyo yaba ihagije bihagije amakuru atandukanye yo kwisuzumisha yatanzwe nuwakiriye, kandi biremewe niyerekwa rya muganga.Icyatsi kibisi gikoreshwa nkibisanzwe mugihe cyo gukemura, kugirango ibara ryo hasi cyane rigaragare neza mwirabura.Urwego rwohejuru rwinshi ni ibara ryera ryera ariko rirabagirana, hindura kurwego rwose rwimyenda yurwego rukize kandi rushobora kugaragara.

2. Gukemura ibibazo

Sensitivity bivuga ubushobozi bwigikoresho cyo gusuzuma ultrasound kugirango tumenye kandi twerekane intera igaragara.Igizwe ninyungu zose, hafi yo guhagarika umurima nindishyi za kure cyangwa inyungu zimbitse (DGC).Inyungu zose zikoreshwa muguhindura amplification ya voltage, ikigezweho cyangwa imbaraga zikimenyetso cyakiriwe cyibikoresho byo gusuzuma ultrasonic.Urwego rwinyungu zose zigira ingaruka muburyo bwo kwerekana ishusho, kandi gukemura ni ngombwa.Muri rusange, umwijima usanzwe ukuze watoranijwe nkicyitegererezo cyo guhindura, kandi ishusho nyayo yumwijima wiburyo irimo imitsi yo hagati ya hepatike hamwe nu mitsi wiburyo ya hepatike yerekanwa na subcostal oblique incision, kandi inyungu zose zirahinduka kuburyo echo yumwijima yumwijima parenchyma hagati yishusho (agace ka 4-7cm) ni hafi ishoboka kurwego rwimyenda igaragara hagati yikigereranyo.Inyungu zimbitse (DGC) zizwi kandi nkigihe cyo kwishyurwa igihe (TGC), guhindura igihe (STC).Mugihe intera yibyabaye ultrasonic yiyongera kandi ikagabanuka mubikorwa byo gukwirakwiza umubiri wumuntu, ikimenyetso cyegereye umurima muri rusange kirakomeye, mugihe ibimenyetso bya kure-bidakomeye.Kugirango ubone ishusho yuburebure bumwe, hafi yo guhagarika imirima hamwe nindishyi za kure zigomba gukorwa.Buri bwoko bwibikoresho bya ultrasonic muri rusange bifata ubwoko bubiri bwindishyi: ubwoko bwo kugenzura uturere (ubwoko bwo kugenzura imisozi) nubwoko bugenzura (ubwoko bugenzura intera).Intego yacyo ni ugukora echo yumurima hafi (tissue nto) hamwe numurima wa kure (tissue ndende) hafi yurwego rwimyenda yumurima wo hagati, ni ukuvuga kubona ishusho imwe kuva kumucyo kugeza kumurongo wijimye, kugirango byorohereze gusobanura no gusuzuma abaganga.

3. Guhindura urwego rugaragara

Ikirangantego (cyerekanwe muri DB) bivuga urutonde rwibimenyetso byo hasi cyane kugeza hejuru ya echo ishobora kwongerwaho na amplifier yibikoresho byo gusuzuma ultrasonic imaging.Ikimenyetso cya echo cyerekanwe kumashusho munsi yumunsi ntigaragara, kandi ikimenyetso cya echo hejuru yikirenga ntigikomeza.Kugeza ubu, urwego rugenda rwerekana ibimenyetso bikomeye kandi byo hasi cyane muri echo mugikoresho rusange cyo gusuzuma amashusho ya ultrasonic ni 60dB.ACUSONSEQUOIA ikoresha mudasobwa ultrasound imashini igera kuri 110dB.Intego yo guhindura urwego rugaragara ni kwagura byimazeyo ibimenyetso bya echo bifite agaciro gakomeye ko gusuzuma no guhagarika cyangwa gusiba ibimenyetso bidafite akamaro.Urwego rufite imbaraga rugomba guhinduka kubuntu ukurikije ibisabwa byo gusuzuma.

Guhitamo uburyo bukwiye bwo guhitamo ntibigomba gusa kwerekana ibimenyetso byerekana ibimenyetso bito kandi bidakomeye imbere muri lesion, ariko kandi byerekana ko bigaragara cyane kumupaka wibisebe hamwe na echo ikomeye.Urwego rusange rwingirakamaro rusabwa mugupima ultrasound yo munda ni 50 ~ 55dB.Nyamara, kugirango witondere kandi usesenguye kandi usesengure ibice byindwara ya pologologi, intera nini yingirakamaro irashobora gutoranywa kandi itandukaniro ryamashusho rishobora kugabanuka kugirango ukungahaze amakuru yo kwisuzumisha yerekanwe mumashusho acoustic.

4. Guhindura imikorere yibanda kumurongo

Gusikana ibice byabantu hamwe nibiti byibanze bya acoustic birashobora kunoza imikurire ya ultrasound kumiterere myiza yibice byibandwaho (lesion), kandi bikagabanya kubyara ibihangano bya ultrasonic, bityo bikazamura ubwiza bwibishusho.Kugeza ubu, kwibanda kuri ultrasonic bifata cyane cyane guhuza imbaraga-nyayo ya electron yibanda cyane, ihindagurika rya aperture, lens acoustic hamwe na tekinoroji ya kristu, kugirango gutekereza no kwakira ultrasonic bigere kumurongo wuzuye wibanze cyane hafi, hagati na kure imirima.Kubikoresho byo kwisuzumisha ultrasonic hamwe numurimo wo gutoranya ibice byibanze, ubujyakuzimu bwo kwibanda burashobora guhindurwa nabaganga igihe icyo aricyo cyose mugihe cyo kubaga.
