Rudzi Doppler VS Simba Doppler

 

Chii chinonzi Color Doppler?

 

Iyi mhando yeDoppler inoshandura masaisai enzwi kuita mavara akasiyana ekuratidzira kuratidza kumhanya uye mafambiro ekuyerera kweropa munguva chaiyo.

Inogona kushandiswa kufungidzira kuyerera kweropa kuburikidza netsinga dzako dzeropa nekukwenya mafungu e-high-frequency sound waves (ultrasound) kubva pakutenderera kwemasero matsvuku eropa.Yenguva dzose ultrasound inoshandisa masaisai enzwi kugadzira mifananidzo, asi haigone kuratidza kubuda kweropa.

Chii chinonzi Power Doppler?

Power Doppler yakavakirwa pakuonekwa kwekuyerera kweropa kunononoka, inobvisa frequency yekuchinja chiratidzo, uye inoshandisa iyo amplitude siginecha inoumbwa neyakapararira simba remasero matsvuku eropa kuratidza kugoverwa kwetsinga diki dzeropa zvakanyanya.

Ndeupi Musiyano pakati peColor Doppler uye Power Doppler?

Colour Doppler inoshandura kuyerwa kwekuyerera kweropa kuita akatevedzana emavara kubatsira kuratidza kumhanya uye nzira yekuyerera kweropa nemudziyo.

Power Doppler inotonyanya kunzwisiswa kupfuura ruvara Doppler pakuona kuyerera kweropa, kunyangwe isingapi ruzivo nezve gwara rekuyerera kweropa.
