Chii chinonzi Doppler Imaging?

Kufungidzira maDoppler neUltrasound kugona kuongorora nekuyera kuyerera kweropa mutsinga dzakasiyana-siyana, tsinga dzeropa, netsinga dzeropa. Kazhinji zvinomiririrwa nemufananidzo unofamba uri pachikirini chesystem yeultrasound, munhu anogona kuona bvunzo yeDoppler kubva pakuyerera kweropa rine mavara anoonekwa pamufananidzo weultrasound. Doppler inogona kududzira mavara ari mumufananidzo zvichibva pakuyera kuyerera kweropa munzvimbo chaiyo iri kutorwa.

Kufungidzira maDoppler kwakasiyana nekufungidzira kweultrasound yechinyakare nenzira imwe chete huru: hakuratidzi chimiro chero chipi zvacho. Ultrasound yechinyakare inopa mifananidzo yezvimiro zvakasiyana-siyana, nhengo, uye tsinga kuti iongorore kukura, kuputika, matambudziko echimiro, nezvimwe zvirwere zvakawanda zvinogona kuitika. Kufungidzira maDoppler, kune rumwe rutivi, kunongoratidza mufananidzo wekuyerera kweropa chete.

Kufungidzira maDoppler neUltrasound inzira inozivikanwa pasi rose uye inoremekedzwa zvikuru nekuda kwekusapinda kwayo mumuviri uye kusashandisa maradioactive. Doppler haishandisi ma radiation kana maficha anopinza, asi inoshanda nenzira imwecheteyo semimwe michina yekufungidzira maultrasound; ichishandisa mafungu eruzha anoonekwa uye anoshandurwa kuita mavara, mifananidzo, uye mafambiro akasiyana-siyana.

Mabasa eDoppler Imaging:

Kufungidzira maDoppler kwakasiyana nekufungidzira kwemaultrasound nenzira yechinyakare nenzira imwe chete huru: hakuratidzi chimiro chero chipi zvacho. Ultrasound yechinyakare inopa mifananidzo yemaumbirwo akasiyana-siyana, nhengo, uye tsinga kuti iongorore kukura, kuputika, matambudziko emaumbirwo, nezvimwe zvirwere zvakawanda zvinogona kuitika.

Kufungidzira madoppler, kune rumwe rutivi, kunoshandiswa kuona kuyerera kweropa uye njodzi dzakasiyana-siyana dzinogona kuitika mutsinga, tsinga dzeropa, uye tsinga dzeropa. Kufungidzira madoppler kunowanzo shandiswa kuona mavharo eropa, kuona mavharuvhu asingashande zvakanaka mutsinga, kuona kana tsinga dzakavharika, kana kuona kuderera kwekufamba kweropa mumuviri wese. Zvese izvi zvinogona kutyisidzira hutano nehupenyu zvinogona kuonekwa uye kudzivirirwa neDoppler imaging.

Vanhu vanoshandisa Doppler imaging pamashandisirwo akasiyana: Semuenzaniso, cardiac Doppler, iyo inotarisa kuyerera kweropa kuenda nekubva pamwoyo, chinhu chakajairika uye chakakosha pakuongororwa kwechirwere chemwoyo.

Mamwe mashandisirwo akakurumbira eDoppler anosanganisira transcranial Doppler (kutevera kuyerera kweropa muuropi nemumusoro), vascular Doppler, uye general venous ne arterial Doppler.
