Isixhobo sokuxilonga se-ultrasonic
Ngophuhliso oluqhubekayo lomfanekiso we-b-uhlobo lwe-ultrasound yomfanekiso womfanekiso wesibindi, isizukulwana sokuqala se-single-probe esicothayo somfanekiso we-B-uhlobo lwe-tomography sisetyenziswe kwiklinikhi.Isizukulwana sesibini sokuskena okukhawulezileyo koomatshini kunye nesantya esiphezulu-isantya sokwenyani se-multi-probe ye-electronic scanning ultrasonic tomography scanner yavela.Isizukulwana, ukusetyenzwa komfanekiso wekhompyuter njengeyona ndlela iphambili yokuzenzekela, iqondo eliphezulu lokulinganisa isizukulwana sesine sezixhobo ze-imaging ze-ultrasonic kwinqanaba lesicelo.Okwangoku, ukuxilongwa kwe-ultrasonic kuphuhla kwi-specialization kunye nobukrelekrele.
I-Ultrasonic tomography iphuhliswe ngokukhawuleza kwiminyaka yamuva nje, kwaye izixhobo eziphambili kakhulu zifakwa kwisicelo seklinikhi phantse minyaka yonke.Ngoko ke, kukho iintlobo ezininzi zezixhobo, kunye nezakhiwo ezahlukeneyo ngeenjongo ezahlukeneyo.Okwangoku, kunzima ukufumana isixhobo se-ultrasonic tomography esinokuchaza isakhiwo esipheleleyo sezi zixhobo ezahlukeneyo.Kweli phepha, sinokunika kuphela isingeniso esifutshane kolu hlobo lwezixhobo zokuxilonga ngokuthatha i-real-time B - mode ultrasonography njengomzekelo.
Umgaqo osisiseko we
Isixhobo sokuxilonga se-ultrasonic sohlobo lwe-B (esibizwa ngokuba yi-B-ultrasound) siphuhliswa ngesiseko se-A-ultrasound, kwaye umgaqo wayo wokusebenza ngokusisiseko ufana ne-ultrasound, kodwa kunye nokusetyenziswa kwe-teknoloji ye-imaging ye-pulse echo.Ke ngoko, ukubunjwa kwayo okusisiseko kukwaqulunqwe neprobe, isekethe yokuhambisa, ukufumana isekethe kunye nenkqubo yokubonisa.
Umahluko ngulo:
① Isiboniso se-amplitude modulation ye-B ultrasound sitshintshwa ibe kukuqaqambisa ukumodulisa umboniso we-A ultrasound;
② Ubunzulu bexesha lokuskena ubunzulu be-B-ultrasound bongezwa kwicala elithe nkqo kwisiboniso, kwaye inkqubo yokuskena isifundo nge-acoustic beam ihambelana nokuskena kokufuduka kwicala elithe tye lomboniso;
③ Kwikhonkco ngalinye le-echo signal processing kunye nokulungiswa komfanekiso, ininzi ye-B-ultrasound isebenzisa ikhompyutha ekhethekileyo yedijithali ukulawula ukugcinwa kunye nokulungiswa kwesignali yedijithali kunye nokusebenza kwenkqubo yokucinga yonke, ephucula kakhulu umgangatho womfanekiso.
Ubungakanani besicelo ekuxilongweni kweklinikhi
Uhlobo lwe-B-real-time imager lusetyenziselwa ukuxilongwa ngokusekelwe kwiimpawu zomfanekiso ophosakeleyo, ngokukodwa kubandakanywa i-morphology yomfanekiso, ukukhanya, isakhiwo sangaphakathi, i-echo yomda, i-echo jikelele, imeko yangasemva ye-viscera kunye nokusebenza kwezicubu ezijikelezayo, njl. kunyango lweklinikhi.
1. Ukufunyanwa kwi-obstetrics kunye ne-gynecology
Ingabonisa intloko yosana, umzimba wosana, indawo yomntwana, intliziyo yosana, iplacenta, ukukhulelwa kwe-ectopic, ukuzala umntwana ongasekhoyo, imole, i-anencephaly, ubunzima be-pelvic, njl. njl., inokuthelekelela inani leeveki zokumitha ngokobungakanani bentloko yosana.
2, inkcazo yamalungu angaphakathi omzimba womntu kunye nokufunyanwa kwesakhiwo sayo sangaphakathi
Njengesibindi, i-gallbladder, i-spleen, izintso, i-pancreas, isinyi kunye nezinye iimilo kunye nezakhiwo zangaphakathi;Ukwahlula ubume bobunzima, njengezifo ezingenayo zihlala zingenayo i-echo yomda okanye umphetho awukho igesi, ukuba ubunzima bune-membrane, i-echo yomda wayo kunye nomboniso ogudileyo;Iyakwazi ukubonisa amalungu ashukumisayo, afana nokushukuma kweevalvu zentliziyo.
3. Ukubonwa kwezicubu kumalungu angaphandle
Ukuhlola kunye nokulinganisa ukulungelelaniswa kwezakhiwo zangaphakathi ezifana namehlo, i-thyroid gland kunye nebele.
