Xa sijonga izinto ngamehlo ethu, kukho iindlela ezahlukahlukeneyo ‘esijonga’ ngazo..Maxa wambi, sisenokukhetha ukujonga phambili kuphela njengaxa sifunda isaziso eludongeni.Okanye sinokujonga ngokuthe tye xa sihlola ulwandle.Ngendlela efanayo, kukho iindlela ezininzi ezahlukeneyo i-ultrasound probe “enokujonga” ngayo izinto.Ezi ndlela zibizwa ngokuba "iindlela" kwaye ezi ziya kuchazwa ngezantsi.Iimowudi zithiywe ngoonobumba kwaye zinokuvakala zibhidekisa kakhulu.Nangona kunjalo, siya kuxoxa ngamnye ngokulandelelana kwaye uya kuthi, ekugqibeleni, uqonde iziseko zazo.

A Imowudi

I-A-mode yeyona ndlela ilula yomfanekiso we-ultrasound kwaye ayisetyenziswa rhoqo.

Umfanekiso uboniswa kwiscreen kumlinganiselo omnye.Iliza le-ultrasound eliphuma kwiprobe lihamba ngendlela emxinwa efana nepensile ethe tye.Itransducer enye ihlola umzimba.Usebenzisa ufikelelo lwe-X kunye no-Y, ulwazi oluqokelelweyo lucwangciswe kwiscreen njengomsebenzi wobunzulu.Imowudi ye-A, okanye i-amplitude mode, ilungele ukulinganisa imigama.I-A-mode ultrasound ingasetyenziselwa ukufumanisa ama-cysts okanye amathumba.

BImowudi

Imowudi ye-B, ekwaziwa njengemowudi ye-2D, ibonisa umboniso omacala mabini.Ukukhanya komfanekiso, ngakumbi kwaye kugxininise i-echo (okuyi-reverberation yamaza omsindo akhutshwa yi-transducer).Phantse njengayo yonke eminye imifanekiso ye-ultrasound, indawo omi kuyo umfanekiso ixhomekeke kwi-engile apho i-transducer ibekwe khona.

I-C-Mode isebenza ngokufanayo ne-B-Mode, nangona ayizange iphuhliswe ngokupheleleyo.Ukusebenzisa idatha kunye noluhlu lobunzulu ukusuka kwi-A-Mode, i-transducer ihambe iye kwi-B-Mode (okanye i-2D mode) kwaye iphonononge yonke ingingqi kubunzulu obusetyenziswe ekuqaleni kwimifanekiso emacala amabini.

Imowudi ye-M:

U-M umele intshukumo.Kwimowudi ye-m ulandelelwano olukhawulezayo lwe-B-mowudi yokuskena imifanekiso yayo ilandelana ngokulandelelana kwisikrini yenza oogqirha babone kwaye balinganise uluhlu lwentshukumo, njengoko imida yamalungu evelisa ukubonakaliswa ihamba ngokumalunga ne-probe.

Imowudi yeDoppler:

Le ndlela isebenzisa isiphumo seDoppler ekulinganiseni nasekuboneni ukuhamba kwegazi.I-doppler sonography idlala indima ebalulekileyo kwiyeza.I-Sonography inokuphuculwa kunye nemilinganiselo ye-Doppler, esebenzisa i-Doppler effect ukuvavanya ukuba izakhiwo (igazi eliqhelekileyo) zihamba zisiya okanye zikude kwi-probe, kunye nesantya esihambelanayo.Ngokubala ukutshintshwa okuphindaphindiweyo komthamo othile wesampulu, umzekelo, i-jet yegazi ehamba phezu kwevalve yentliziyo, isantya kunye nesalathiso sinokumiselwa kwaye sibonwe.Oku kubaluleke kakhulu kwizifundo ze-cardiovascular (i-sonography ye-vasculature system kunye nentliziyo) kwaye ibalulekile kwiindawo ezininzi ezifana nokumisela ukujikeleza kwegazi kwi-vasculature yesibindi kwi-portal hypertension.Ulwazi lwe-Doppler luboniswa ngokwemizobo kusetyenziswa i-Doppler ebonakalayo, okanye njengomfanekiso usebenzisa i-Doppler yombala (i-Doppler yolwalathiso) okanye i-Doppler yamandla (i-Doppler engaqondiyo).Olu tshintsho lwe-Doppler luwela kuluhlu oluvakalayo kwaye luhlala luvezwa ngokuvakalayo kusetyenziswa izithethi ze-stereo: oku kuvelisa isandi esahluke kakhulu, nangona sisenziwe, sibetha.
