Ibara rya Doppler VS Imbaraga

 

Doppler y'amabara ni iki?

 

Ubu bwoko bwa Doppler buhindura amajwi mumajwi atandukanye kugirango yerekane kwerekana umuvuduko nicyerekezo cyamaraso mugihe nyacyo

Irashobora gukoreshwa mukugereranya amaraso atembera mumitsi yamaraso mugukubita amajwi menshi yumurongo mwinshi (ultrasound) kugirango utemberane mumaraso atukura.Ultrasound isanzwe ikoresha amajwi kugirango itange amashusho, ariko ntishobora kwerekana amaraso.

Imbaraga Doppler ni iki?

Power Doppler ishingiye ku kumenya ibimenyetso bitembera neza mu maraso, ikuraho ikimenyetso cyo guhinduranya inshuro, kandi ikoresha ibimenyetso bya amplitude byakozwe ningufu zitatanye zingirabuzimafatizo zitukura kugirango zerekane ikwirakwizwa ryimitsi mito mito.

Ni irihe tandukaniro riri hagati y'amabara Doppler na Doppler?

Ibara Doppler ihindura ibipimo byamaraso muburyo butandukanye kugirango ifashe kwerekana umuvuduko nicyerekezo cyamaraso atembera mumitsi.

Imbaraga Doppler niyo yunvikana kuruta amabara Doppler mugutahura amaraso, nubwo idatanga amakuru kubyerekeranye nicyerekezo cyamaraso.

 

Dawei Ibikoresho byo mu rwego rwo hejuru ultrasonica ibikoresho byo gusuzuma,DW-T8, ntabwo ifite amashusho ya Doppler gusa (PDI), ariko Amashusho Yerekana Amashanyarazi (DPDI).
