01 Chii chinonzi ultrasound kuongororwa?
Kutaura kuti chii chinonzi ultrasound, tinofanira kutanga tanzwisisa kuti ultrasound chii.Ultrasonic wave imhando yeizwi wave, inova ye mechanical wave.Masaisai eruzha ane mafambiro ari pamusoro pepamusoro pezvinonzwikwa nenzeve yemunhu (20,000 Hz, 20 KHZ) ari Ultrasound, ukuwo zvekurapa ultrasound frequencies zvinowanzobva pa2 kusvika 13 miriyoni Hz (2-13 MHZ).Iyo yekufungidzira musimboti wekuongororwa kwe ultrasound ndeiyi: Nekuda kwehuremu hwenhengo dzemunhu uye mutsauko mukumhanya kwekupararira kwemafungu eruzha, Ultrasound icharatidzwa mumadhigirii akasiyana, probe inogamuchira iyo ultrasound inoratidzwa nenhengo dzakasiyana uye inogadziriswa nekombuta. gadzira mifananidzo ye ultrasonic, nekudaro ichipa iyo ultrasonography yenhengo imwe neimwe yemuviri wemunhu, uye sonographer inoongorora idzi ultrasonography kuti iwane chinangwa chekuongororwa uye kurapwa kwezvirwere.
02 Ultrasound inokuvadza muviri wemunhu here?
Nhamba huru yezvidzidzo uye mashandisirwo anoshanda zvakaratidza kuti kuongororwa kweultrasound kwakachengeteka kumuviri wemunhu, uye hatifanirwe kunetseka nezvazvo.Kubva pakuongororwa kwemusimboti, Ultrasound ndiko kutapurirana kwemechanic vibration mukati, kana ichipararira mukati mebiological medium uye iyo irradiation dose inodarika imwe chikumbaridzo, inova nekushanda kana kurongeka kweiyo biological medium, inova biological effect. zve ultrasound.Zvinoenderana nemaitiro ayo echiito, inogona kukamurwa kuita: mechanical effect, thixotropic effect, thermal effect, acoustic flow effect, cavitation effect, nezvimwewo, uye mhedzisiro yayo yakashata inonyanya kuenderana nehukuru hwedosi uye kureba kwenguva yekuongorora. .Nekudaro, isu tinogona kuzorora kugutsikana kuti ikozvino ultrasonic diagnostic instrument fekitori iri mukunyatso kutevedzera neUnited States FDA neChina CFDA zviyero, iyo dose iri mukati meiyo yakachengeteka renji, chero bedzi zvine musoro kutonga kwenguva yekuongorora, ultrasound inspection haina. kukuvadza kumuviri wemunhu.Pamusoro pezvo, Royal College of Obstetricians and Gynecologists inokurudzira kuti kanenge mana prenatal ultrasounds inofanira kuitwa pakati pekuiswa uye kuberekwa, izvo zvakakwana kuratidza kuti ultrasounds inozivikanwa pasi rose seyakachengeteka uye inogona kuitwa nechivimbo chakakwana, kunyange mumwana.
03 Sei zvichidikanwa dzimwe nguva usati waongororwa "Mudumbu usina chinhu", "weti yakazara", "weti"?
Kungave “kutsanya”, “kubata weti”, kana “kuita weti”, kunzvenga dzimwe nhengo dziri mudumbu kuti dzivhiringe nhengo dzatinofanira kuongorora.
Kune kumwe kuongororwa kwenhengo, senge chiropa, bile, pancreas, spleen, itsvo tsinga, midziyo yemudumbu, nezvimwewo, dumbu risina chinhu rinodiwa usati waongororwa.Nokuti muviri wemunhu mushure mekudya, chirwere chemudumbu chichabudisa gasi, uye ultrasound "inotya" gasi.Kana ultrasound inosangana negasi, nekuda kwekusiyana kukuru mukufambiswa kwegasi uye matishu evanhu, yakawanda ye ultrasound inoratidzwa, saka nhengo dziri shure kwegesi haigoni kuratidzwa.Zvisinei, nhengo dzakawanda mudumbu dziri pedyo kana kuseri kwegastrointestinal turakiti, saka dumbu risina chinhu rinodiwa kuti udzivise kukanganisa kwegasi mudumbu remuviri pamhando yemufananidzo.Kune rumwe rutivi, mushure mekudya, iyo bile iri mu gallbladder ichabudiswa kuti ibatsire kugaya, gallbladder ichaderera, uye kunyange haigoni kuonekwa zvakajeka, uye chimiro uye kuchinja kusina kujairika mairi zvichave zvisingaoneki.Saka, pamberi pekuongororwa kwechiropa, bile, pancreas, spleen, mudumbu mitsipa mikuru yeropa, itsvo midziyo, vakuru vanofanira kutsanya kweanopfuura maawa masere, uye vana vanofanira kutsanya kweinenge maawa mana.
Paunenge uchiita ultrasound bvunzo dzeurinary system uye gynecology (transabdominal), zvinodikanwa kuzadza dundira (kubata weti) kuitira kuratidza nhengo dzakakodzera zvakajeka.Izvi zvinodaro nekuti kune ura pamberi pedundira, pane kazhinji kukanganiswa kwegasi, kana tikabata weti kuti izadze dundira, zvinongoerekana zvasundira ura "kure", unogona kuita kuti dundira riratidze zvakajeka.Panguva imwecheteyo, bladder mune yakazara mamiriro anogona kuratidza zvakajeka dundira uye dundira maronda emadziro.Zvakafanana nebhegi.Kana yapeputswa, hatione zviri mukati, asi kana tikaivhura, tinoona.Dzimwe nhengo, dzakadai seprostate, chibereko, uye appendices, zvinoda dundira rakazara sehwindo rakajeka kuti riongorore zviri nani.Nokudaro, nokuda kwezvinhu izvi zvekuongorora zvinoda kubata weti, kazhinji inwa mvura yakachena uye usaita weti 1-2 maawa asati aongororwa, uye wozotarisa kana pane chinangwa chiri pachena chekuita weti.
Iyo gynecological ultrasound yatataura pamusoro ndeye ultrasound bvunzo kuburikidza nemadziro edumbu, uye zvinodikanwa kubata weti isati yaongororwa.Panguva imwecheteyo, kune imwe gynecologic ultrasound kuongorora, kureva, transvaginal gynecologic ultrasound (inowanzozivikanwa se "Yin ultrasound"), inoda weti isati yaongororwa.Izvi zvinodaro nekuti transvaginal ultrasound iprobe yakaiswa mukati memukadzi wemukadzi, ichiratidza chibereko uye maapendages maviri kumusoro, uye dundira iri pazasi pepamberi peiyo uterine appendages, kana yangozara kumusoro, inosundira chibereko uye maviri. maappendages kumashure, achivaita kure neprobe yedu, zvichikonzera mibairo isina kunaka yekufungidzira.Mukuwedzera, transvaginal ultrasound inowanzoda kudzvinyirirwa kuongororwa, ichaitawo kuti dundira, kana dundira rakazara panguva ino, murwere achava nekusagadzikana kwakajeka, zvinogona kukonzera kupotsa kuongororwa.
04 Sei zvinhu zvinonamira?
Paunenge uchiita ongororo ye ultrasound, mvura inoonekera yakashandiswa nachiremba ndeye coupling agent, inova mvura-based polymer gel kugadzirira, iyo inogona kuita kuti probe uye muviri wedu wevanhu ubatane zvisina musono, kudzivirira mhepo kubva pakukanganisa kufambiswa kwemafungu e ultrasonic, uye kuvandudza zvakanyanya kunaka kweiyo ultrasonic imaging.Uyezve, ine mamwe maitiro ekuzora, zvichiita kuti probe iwedzere kutsvedzerera pamusoro pemuviri wemurwere, izvo zvinogona kuchengetedza simba rachiremba uye zvakanyanya kuderedza kusagadzikana kwemurwere.Mvura iyi haina chepfu, haina kunaka, haina hasha, haiwanzokonzerese kusawirirana, uye nyore kuchenesa, kuoma nekukurumidza, tarisa nepepa rakapfava tauro kana tauro rinogona kupukutwa, kana kucheneswa nemvura.
05 Chiremba, bvunzo yangu yanga isiri "color ultrasound" here?
Sei uchitarisa mifananidzo mu "dema nechena"
Chokutanga pane zvose, unofanirwa kunzwisisa kuti ruvara rwe ultrasound haisi ruvara rweTV mudzimba dzedu.Mukiriniki, color ultrasound inoreva ruvara rweDoppler ultrasound, iyo inoumbwa nekusimudza chiratidzo chekuyerera kweropa pamufananidzo wemativi maviri eB-ultrasound (B-mhando ultrasound) mushure mekukodha kwemavara.Pano, "ruvara" rinoratidza mamiriro ekuyerera kweropa, patinoshandura ruvara rweDoppler basa, chifananidzo chichaonekwa chitsvuku kana chebhuruu chekuyerera kweropa.Iri ibasa rakakosha mune yedu ultrasound yekuongorora maitiro, iyo inogona kuratidza kuyerera kweropa remitezo yedu yakajairika uye kuratidza kubuda kweropa kwenzvimbo yekukuvadza.Iwo maviri-dimensional mufananidzo we ultrasound anoshandisa akasiyana grey mwero kumiririra akasiyana echoes enhengo uye maronda, saka inotaridzika "dema uye chena".Semuenzaniso, mufananidzo uri pazasi, kuruboshwe mufananidzo wemativi maviri, unonyanya kuratidza chimiro chenyama yemunhu, inotaridzika "dema uye chena", asi kana yakasimudzwa pane yakatsvuka, yebhuruu ruvara rwekuyerera kweropa chiratidzo, inova iyo chaiyo ruvara. "ruvara ultrasound".
Kuruboshwe: "Dema uye chena" Ultrasound Kurudyi: "Muvara" ultrasound
06 Munhu wose anoziva kuti mwoyo inhengo inokosha zvikuru.
Saka chii chaunoda kuziva nezve cardiac ultrasound?
Cardiac echocardiography kuongorora kusingapindiki uchishandisa tekinoroji yeultrasound kuona zvine simba saizi, chimiro, chimiro, vharafu, hemodynamics uye kushanda kwemoyo kwemoyo.Iine zvakakosha kuongororwa kukosha kwekuzvarwa kwechirwere chemoyo uye chirwere chemoyo, chirwere chevalvular uye cardiomyopathy inobatwa nezvinhu zvakawanikwa.Vasati vaita ongororo iyi, vanhu vakuru havadi kuburitsa mudumbu, uye havadi mamwe magadzirirwo akakosha, teerera kumisa kushandiswa kwezvinodhaka zvinokanganisa kushanda kwemoyo (zvakadai sedigitalis, nezvimwewo), pfeka zvipfeko zvakasununguka kuti zvive nyore kuongorora.Kana vana vachiita cardiac ultrasound, nokuti kuchema kwevana kuchakanganisa zvakanyanya kuongororwa kwechiremba kwemwoyo weropa, vana vari pasi pemakore matatu vanowanzokurudzirwa kuti vanyaradze mushure mekuongororwa nerubatsiro rwevana chiremba.Kune vana vanopfuura makore matatu, sedation inogona kutsanangurwa maererano nemamiriro emwana.Kune vana vane kuchema kwakanyanya uye vasingakwanisi kushandira pamwe nekuongorora, zvinokurudzirwa kuti uite kuongorora mushure mekugadzirisa.Kune vana vakawanda vanobatira pamwe, unogona kufunga nezvekuongorora kwakananga kunoperekedzwa nevabereki.
