Sonography. Yintoni na kwaye yintoni na sisiseko indlela zophando

Xa ugqirha ibhekisa isigulane ultrasound, imibuzo emininzi kakhulu ayikho ngokuqhelekileyo kuvuka. Kodwa ukuba ukuqeshwa wasebenzisa igama elithi "ultrasound" umangalisayo, imibuzo ukuthululwa ezifana nee-ertyisi. Ngoko ke, kuyimfuneko ukuba ukuqonda, sonography - ntoni na? Kwaye kwezinye iimeko, isigulane banikwa umsebenzi ofanayo.

Association

Izayamaniso isigulane yokuqala ezinxulumene ukulala, kodwa ultrasound ayinanto yakwenza naloo nto. Ultrasound kunye sonography - amagama ahlukeneyo inkqubo efanayo. Kuba uphando efanayo ngamanye amaxesha basebenzisa igama sonography. Ngokusekelwe kule, sinako bafikelele kwisigqibo elula: ultrasound, ultrasound, ultrasound - ntoni na? Le ultrasound uvelisa uvavanyo yemida morphological kunye olusebenzayo Amalungu nezihlunu zabantu.

Yintoni na indlela

Ultrasound indlela esekelwe iimpawu kwamaza cuke ngomzimba ephosiweyo. In bonke abaphilileyo amabhunga ukuba yenziwa nezihlunu loxinano ezahlukeneyo kunye ukuxhathisa. Nale ultrasound lubonakala, refracted, saa okanye ithathe. Ngenxa yoko, umfanekiso kwisixhobo eso siwamkelayo kwenzeka. Loo nto eneneni ukurekhodwa lwemiqondiso echo ultrasound kubonakala ukusuka izinto.

izixhobo Medical for ultrasound (sonography) kusebenzisa kangaphi MHz 1.5 ukuya 29. Le pitch siphezulu ubonakala yi ngendlebe yomntu, 20 kHz. Umfanekiso okubangelwa - hayi nje aya zangaphakathi ilungu okanye ithambo inxalenye-x-reyi, kwaye mapping kwezakhiwo zangaphakathi.

Inkcazelo emfutshane bomashini ultrasound

Ukuqhuba isaveyi usebenzisa umatshini ultrasound zonyango. Sonography - ntoni na? Ingaba zonke iingcinga ayafana? Zeziphi izinto ayimiqulu? Eyona nto intle isixhobo ultrasound izixhobo aqonde physics. ukuqonda ukuba yintoni umphumo piezoelectric, owaziyo ubude Iingoma kunye ezitsho. isigulane Ordinary ngokwaneleyo ukwazi ukuba icebo ibandakanya ezi zinto zilandelayo:

• a generator kwamaza cuke, ngamanye ukubetha generator esikhupha umlilo kwaye ngaxeshanye ofumana imiyalezo kubonakala;
• cuke sensor-transdyusora, nto leyo likwaneklinkhi kukho inani elikhulu transducers pezokristallicheskih kwi woluvo kukho lens ugxininisa evumela ukuba unikel 'ingqalelo kubunzulu oyifunayo.

Iindidi transdyusorov (isivamvo)

Icandelo lokuqala izakwenziwa izixhobo ze-elektroniki. Ukuhlolisisa isivamvo semekhenikhal lwenziwa yi intshukumo element unyulu (ukujikeleza okanye sinyikimisa). The main ethile - imifanekiso unesisombululo esisezantsi, ukungcangcazela kunye nomsebenzi nengxolo. Modern ultrasound sonography wabalahla imodeli eziphelelwe lixesha, wakhetha ukusebenzisa uguqulelo electronic.

abenzi boluvo ezombane izixhobo mihla. imifanekiso Scan zavezwa elektroniki. Lo mfanekiso ucacile ngakumbi kwaye iphelele. Ingxolo nokungcangcazela xa usebenzisa ongekho izixhobo.

ayisuse cuke lwahlulwe lwaba yomgama, khaxa kunye necandelo uhlobo. Ngako oko, le basebenzisa iintlobo 3 cone:

1. Linear. Lisebenzisa rhoqo 5-15 MHz. Iziphumo ummandla umfanekiso uphando kunye nemifanekiso nokugqama, ixabiso ilungu ingqinelana nobubanzi woluvo, kodwa ubunzulu ukuskena angekho ngaphezulu kwe-11 cm. Kunzima ukunika woluvo zoqhagamshelwano uniform ububanzi ukufumana umfanekiso ekumgangatho ophezulu. Isetyenziswa ukuvavanya ndlala, ibele, amalungu naphakathi kunye izihlunu zomzimba.
2. Khaxa. 1,9-7,5 frequency MHz. Ukukrwaqula phezu ubude ezincinane ngaphezu woluvo line. Ukuqinisekisa tight uniform umfowunelwa esikhumbeni. Inika umfanekiso emxinwa, noko nembono ubukhulu, kodwa ubunzulu uhlolo-25 cm. Isetyenziswa iimviwo kwisisu kunye retroperitoneal, inkqubo enzala, amalungu ezinkulu (hip, umzekelo).
3. Sector. Lisebenzisa rhoqo 1.5-5 MHz. Image ezinkulu real. Inika ubuchule scan kubunzulu enkulu. Kakhulu ngokufuthi esetyenziselwa echocardiography.

Iintlobo ngeentlobo abenzi boluvo kusetyenziswa ukuhlola kwamathumbu amalungu, intliziyo, lengqula, isifuba, umqolo kunye namalungu. Ukongeza, kukho microsensors ukuze endoscopy kunye biopsy neenaliti.

Ukuhlolisisa abakhulelweyo

Eyona ndlela ilungileyo uviwo olupheleleyo abafazi abakhulelweyo kuthathwa ukuba sonography computer. izixhobo ezifana kuvumela ingqalelo kakhulu ukuba amalungu karhulumente naleyo yosana olungekazalwa, ekubeni ubukhulu chetyrehsantimetrovogo. Le saveyi ekhuseleke gqibi. Inceda kwiveki yesine yokukhulelwa uphulaphule nokubetha kwentliziyo, ukuchonga ukuphelisa nokoyikiswa kwesisu, sokukhulelwa ukucacisa, ukuchonga ukulibaziseka zophuhliso kunye nezinye ezinxaxhileyo.

Patency le tubes

Imfuneko ukuvavanya patency le tubes kwenzeka kwabasetyhini, abangakwaziyo kumitha ixesha elide. Sonography le tubes - indlela yokuhlola izizathu apho iqanda akakwazi ukuhlangabezana isidoda.

Okokuqala, ugqirha ihlola imo lweHo- zesibeleko, qiniseka ukuba umfazi akakhulelwanga kwaye akukho azikhuli, polyp kunye sites. Ngaphezu koko, umsele wesibeleko ilungiselelwayo saline kwaye zivavanywe kusetyenziswa sonography tubes. Xa le mibhobho ishukunyiswa ekugqithwa, ulwelo amanzi ezivela macala omabini amalungu esiswini. Ukuba engamanzi ayikho lingatshajiswanga, Wawuzalisa icandelo ityhubhu Imibhobho kunye isibeleko, oko ipipi ivaleke. Ultrasound unako ukugqiba ngokuchanileyo indawo kwe block.

Ukuba isigulane uyayiqonda intsingiselo elithi "ultrasound", yintoni na nokuba kutheni ugqirha wakho emiselweyo uviwo, kungavakali ukoyika, ukulungele ukuzalisekisa iimfuno eyimfuneko ugqirha kakuhle libhekisela nkqubo. Kulo kuxhomekeke kwizinto ezininzi. Ngokufuthi, endaweni zoviwo kunye nonyango izigulane bayoyika nisinga amaqhetseba kunye "abaphilisi", belahlekelwa lixesha ezixabisekileyo.
