Patinotarisa zvinhu nemaziso edu, pane nzira dzakasiyana-siyana dzati“notarisa” nadzo..Dzimwe nguva, tingasarudza kutarisa mberi chete sepatinoverenga chiziviso pamadziro.Kana kuti tingatarisa takatarirana tichitarisa gungwa.Nenzira yakafanana, kune nzira dzakawanda dzakasiyana-siyana iyo ultrasound probe inogona "kutarisa" zvinhu.Idzi nzira dzinonzi "modes" uye idzi dzichatsanangurwa pazasi.Iwo mamodhi akatumidzwa nemabhii uye anogona kunzwika kuvhiringa.Nekudaro, isu tichakurukura yega yega uye iwe, mukupedzisira, uchanzwisisa izvo zvekutanga.

A Mode

A-modhi ndiyo yakareruka fomu ye ultrasound imaging uye haiwanzo shandiswa.

Mufananidzo wacho unoratidzwa pahwindo mune imwe dhigirii.Iyo ultrasound wave inobuda muprobe inofamba nepenzura yakamanikana-yakafanana nzira yakatwasuka.Transducer imwe chete inoongorora muviri.Uchishandisa X uye Y kuwana, iyo yakaunganidzwa ruzivo inozorongwa pachiratidziro sebasa rekudzika.A-modhi, kana amplitude modhi, yakanakira kuyera madaro.A-mode ultrasound inogonawo kushandiswa kuwana cysts kana mapundu.

BMode

B-Mode, inozivikanwawo se2D modhi, inopa ratidziro yemativi maviri.Kujeka kwechifananidzo, kunowedzera zvakanyanya uye kunonangana echo (iyo inodzokororwa yemafungu anonzwika ayo transducer inoburitsa) ndeye.Senge mimwe mifananidzo yese yeultrasound, nzvimbo yemufananidzo inotsamira pakona iyo iyo transducer inoiswa.

C-Mode inoshanda zvakafanana neB-Mode, kunyangwe isina kugadzirwa kusvika pakukwanisa kwayo kuzere.Uchishandisa data uye huwandu hwehudzamu kubva kuA-Mode, transducer yobva yaenda kuB-Mode (kana 2D modhi) uye inoongorora dunhu rese pakadzika yaimboshandiswa mumifananidzo yemativi maviri.

M mode:

M anomirira kufamba.Mu-m-modhi kukurumidza kutevedzana kweB-mode scans ine mifananidzo inoteedzana munhevedzano pachiratidziro inoita kuti vanachiremba vaone uye kuyera huwandu hwekufamba, sezvo miganhu yenhengo inoburitsa maratidziro inofamba ichienderana neprobe.

Doppler mode:

Iyi modhi inoshandisa iyo Doppler mhedzisiro mukuyera uye kuona kuyerera kweropa.Doppler sonography inoita basa rakakosha mukurapa.Sonography inogona kukwidziridzwa nezviyero zveDoppler, izvo zvinoshandisa iyo Doppler mhedzisiro kuona kana zvimiro (chaicho ropa) zviri kufamba zvichienda kana kure kure nekuferefeta, uye nekumhanya kwayo.Nekuverenga mafambiro ekuchinja kweimwe sampuli vhoriyamu, semuenzaniso, jeti yeropa inoyerera pamusoro pevhavha yemoyo, kumhanya kwayo uye kwainotungamira inogona kutsanangurwa uye kuoneswa.Izvi zvinonyanya kukosha muzvidzidzo zvemwoyo (sonography yevasculature system nemoyo) uye inokosha munzvimbo dzakawanda dzakadai sekugadzirisa reverse blood flow in the chiropa vasculature in portal hypertension.Ruzivo rweDoppler runoratidzwa zvine graphical uchishandisa spectral Doppler, kana semufananidzo uchishandisa ruvara Doppler (directional Doppler) kana simba Doppler (isina-directional Doppler).Iyi shanduko yeDoppler inowira munzvimbo inonzwika uye inowanzoratidzwa zvinonzwika uchishandisa stereo speaker: izvi zvinoburitsa yakasarudzika, kunyangwe yekugadzira, pulsing ruzha.
