Zithunzi za Ultrasonic, zomwe zimadziwikanso kuti sonograms, zimapangidwa potumiza ma ultrasound mu minofu pogwiritsa ntchito kafukufuku. Mitsempha ya ultrasound imamveketsa minofu yokhala ndi mawonekedwe osiyanasiyana ndipo imajambulidwa ndikuwonetsedwa ngati chithunzi.

Mitundu yambiri ya zithunzi imatha kupangidwa. Chodziwika kwambiri ndi chithunzi cha B-mode (Kuwala), chomwe chimawonetsa kusakhazikika kwamtundu wamitundu iwiri. Mitundu ina imatha kuwonetsa kuyenda kwa magazi, kuyenda kwa minofu pakapita nthawi, komwe kuli magazi, kukhalapo kwa mamolekyu enaake, kuuma kwa minofu, kapena mawonekedwe a gawo la magawo atatu.

Poyerekeza ndi njira zina zazikulu zowonera zamankhwala, ultrasound ili ndi zabwino zingapo. Amapereka zithunzi munthawi yeniyeni ndipo amatha kunyamula ndipo amatha kubweretsedwa pafupi ndi bedi. Ndiwotsika mtengo kuposa njira zina zojambulira ndipo sigwiritsa ntchito cheza chowopsa cha ionizing. Zosokoneza zimaphatikizapo malire osiyanasiyana pamawonedwe ake, monga kufunikira kwa mgwirizano woleza mtima, kudalira thupi, zovuta kulingalira zojambula kumbuyo kwa fupa ndi mpweya kapena mpweya, komanso kufunikira kwa wogwiritsa ntchito waluso, yemwe nthawi zambiri amaphunzitsidwa.

Zigawo zina za ultrasound zokhudzana ndi GE zomwe titha kupereka:
