Ithuluzi lokuxilonga le-Ultrasonic
Ngokuthuthuka okuqhubekayo kwesithombe se-b-type ultrasound yesithombe sesampula sesibindi, isizukulwane sokuqala sesithombe se-single-probe slow-slow B sohlobo lwe-tomography sisetshenziswe ekusebenzeni komtholampilo.Isizukulwane sesibili sokuskena komshini okusheshayo kanye nesivinini esiphezulu – sesikhathi sangempela se-multi-probe electronic scanning ultrasonic tomography scanner sivele.Isizukulwane, ukucutshungulwa kwesithombe sekhompiyutha njenge-automation ehamba phambili, izinga eliphakeme lokulinganisa isizukulwane sesine semishini ye-imaging ye-ultrasonic esigabeni sokufaka isicelo.Njengamanje, ukuxilongwa kwe-ultrasonic kuyathuthuka ekuqeqesheni nasekuhlakanipheni.
I-Ultrasonic tomography ithuthuke ngokushesha kakhulu eminyakeni yamuva, futhi amathuluzi athuthuke kakhulu afakwa emtholampilo cishe njalo ngonyaka.Ngakho-ke, kunezinhlobo eziningi zamathuluzi, nezakhiwo ezahlukene ngezinhloso ezahlukene.Njengamanje, kunzima ukuthola ithuluzi le-ultrasonic tomography elingachaza ukwakheka okuphelele kwalezi zinsimbi ezihlukahlukene.Kuleli phepha, singanikeza kuphela isingeniso esifushane salolu hlobo lwemishini yokuxilonga ngokuthatha real - time B - mode ultrasonography njengesibonelo.
Umgomo oyisisekelo we
Ithuluzi lokuxilonga i-ultrasonic yohlobo lwe-B (okubhekiselwa kulo ngokuthi i-B-ultrasound) lakhiwa ngesisekelo se-A-ultrasound, futhi isimiso sayo sokusebenza ngokuyisisekelo sifana ne-a-ultrasound, kodwa futhi ukusetshenziswa kobuchwepheshe be-imaging ye-pulse echo.Ngakho-ke, ukwakheka kwayo okuyisisekelo nakho kuhlanganiswe ne-probe, isifunda sokudlulisa, ukuthola isifunda kanye nesistimu yokubonisa.
Umehluko uthi:
① Isibonisi sokuguquguquka kwe-amplitude ye-ultrasound engu-B sishintshelwa ekubonisweni kokuguqulwa kokukhanya kwe-A ultrasound;
② Ukuskena kwesisekelo sesikhathi sokujula kwe-B-ultrasound kwengezwa ohlangothini oluqondile lwesibonisi, futhi inqubo yokuskena isihloko nge-acoustic beam ihambisana nokuskena kokugudluka endaweni evundlile yesibonisi;
③ Kuso sonke isixhumanisi sokucutshungulwa kwesignali ye-echo nokucutshungulwa kwesithombe, iningi le-B-ultrasound isebenzisa ikhompuyutha ekhethekile yedijithali ukulawula ukugcinwa nokucutshungulwa kwesignali yedijithali kanye nokusebenza kwalo lonke uhlelo lokucabanga, oluthuthukisa kakhulu ikhwalithi yesithombe.
Ububanzi besicelo ekuxilongweni komtholampilo
Isithombe sesikhathi sangempela sohlobo lwe-B sisetshenziselwa ukuxilongwa okusekelwe kuzici zesithombe esiyiphutha, ikakhulukazi okuhlanganisa ukumila kwesithombe, ukukhanya, isakhiwo sangaphakathi, i-echo yomngcele, i-echo iyonke, isimo sangemuva se-viscera nokusebenza kwezicubu ezizungezile, njll. Sisetshenziswa kakhulu emithini yomtholampilo.
1. Ukutholwa kwezokubelethisa kanye ne-gynecology
Ingabonisa ikhanda le-fetus, umzimba we-fetus, ukuma kwe-fetus, inhliziyo ye-fetus, i-placenta, ukukhulelwa kwe-ectopic, ukubeletha, imvukuzane, i-anencephaly, isisindo se-pelvic, njll., futhi ingalinganisa inani lamaviki okukhulelwa ngokobukhulu bekhanda lengane.
2, uhlaka lwezitho zangaphakathi zomzimba womuntu kanye nokutholwa kwesakhiwo sawo sangaphakathi
Njengesibindi, inyongo, ubende, izinso, amanyikwe, esinyeni nezinye izimo kanye nezakhiwo zangaphakathi;Hlukanisa ubunjalo besisindo, njengezifo ezingenayo ngokuvamile azinayo i-echo emngceleni noma unqenqema akuyona igesi, uma isisindo sine-membrane, i-echo yomngcele wayo kanye nesibonisi esibushelelezi;Ingakhombisa futhi izitho eziguqukayo, njengokuhamba kwamavalvu enhliziyo.
3. Ukutholwa kwezicubu ezithweni ezingaphandle
Ukuhlola nokulinganisa ukuqondanisa kwezakhiwo zangaphakathi ezifana namehlo, indlala yegilo kanye nebele.
