Tikamaona zinthu ndi maso athu, pali njira zosiyanasiyana zimene ‘timadzionera’..Nthawi zina, tingasankhe kuyang’ana kutsogolo monga mmene timawerengera pakhoma.Kapena tingayang'ane cham'mwamba tikamasanthula nyanja.Mofananamo, pali njira zambiri zosiyana zofufuza za ultrasound "zingayang'ane" zinthu.Njirazi zimatchedwa "modes" ndipo izi zidzafotokozedwa pansipa.Mitunduyi imatchedwa ndi zilembo ndipo imatha kumveka yosokoneza kwambiri.Komabe, tikambirana aliyense motsatana, ndipo pamapeto pake, mudzamvetsetsa zoyambira zawo.
A Mode
A-mode ndiyo njira yosavuta kwambiri yowonera ma ultrasound ndipo sagwiritsidwa ntchito pafupipafupi.
Chithunzicho chikuwonetsedwa pazenera mu gawo limodzi.Mafunde a ultrasound omwe amatuluka mu kafukufukuyu amayenda munjira yopapatiza ngati pensulo yowongoka.Transducer imodzi imasanthula thupi.Pogwiritsa ntchito mwayi wa X ndi Y, zomwe zasonkhanitsidwa zimakonzedwa pazenera ngati ntchito yakuzama.A-mode, kapena matalikidwe, ndi abwino kuyeza mtunda.A-mode ultrasound angagwiritsidwenso ntchito kupeza cysts kapena zotupa.
BMode
B-Mode, yomwe imadziwikanso kuti 2D mode, imapereka chiwonetsero cha mbali ziwiri.Chifaniziro chowala kwambiri, chimakhala champhamvu kwambiri komanso chokhazikika (chomwe ndi kubwereza kwa mafunde a phokoso omwe transducer amatulutsa).Monga pafupifupi zithunzi zina zonse za ultrasound, malo a chithunzicho amadalira pa ngodya yomwe transducer yaikidwa.
C-Mode imagwira ntchito mofanana ndi B-Mode, ngakhale kuti sinapangidwe mokwanira.Pogwiritsa ntchito deta ndi kuzama kwa A-Mode, transducer imasunthira ku B-Mode (kapena 2D mode) ndikuyang'ana dera lonselo mozama lomwe linagwiritsidwa ntchito pazithunzi ziwiri.
M mode:
M amaimira mayendedwe.Mu m-mode kutsatizana kofulumira kwa ma scan a B-mode omwe zithunzi zake zimatsatana motsatizana pazenera zimathandiza madokotala kuwona ndi kuyeza kusuntha kosiyanasiyana, pomwe malire a ziwalo zomwe zimapanga zowunikira zimasuntha molingana ndi kafukufukuyo.
Doppler mode:
Njirayi imagwiritsa ntchito mphamvu ya Doppler poyezera komanso kuwona kuthamanga kwa magazi.Doppler sonography imagwira ntchito yofunika kwambiri pazamankhwala.Sonography imatha kupitilizidwa ndi miyeso ya Doppler, yomwe imagwiritsa ntchito mphamvu ya Doppler kuti iwunikire ngati zida (magazi wamba) zikuyenda kapena kutali ndi kafukufukuyo, komanso kuthamanga kwake.Powerengera kusinthasintha kwafupipafupi kwa voliyumu inayake yachitsanzo, mwachitsanzo, jet ya magazi ikuyenda pa valve ya mtima, liwiro lake ndi mayendedwe ake amatha kutsimikiziridwa ndikuwoneka.Izi ndizothandiza makamaka pamaphunziro amtima (sonography of the vasculature system and heart) ndipo ndizofunikira m'malo ambiri monga kudziwa reverse blood flow mu chiwindi vasculature mu portal hypertension.Zambiri za Doppler zimawonetsedwa pogwiritsa ntchito Doppler yowoneka bwino, kapena ngati chithunzi pogwiritsa ntchito mtundu wa Doppler (Doppler yolunjika) kapena Doppler yamphamvu (yopanda mbali).Kusintha kwa Doppler uku kumagwera m'mawu omveka ndipo nthawi zambiri amawonetsedwa momveka pogwiritsa ntchito olankhula stereo: izi zimatulutsa kamvekedwe kosiyana kwambiri, ngakhale kapangidwe, kamvekedwe.
