ultrasound imaging uye ruvara Doppler ultrasound imaging?
Anenge makore 20 apfuura, mamwe mapiyona akazvipira kutanga gadziriro dzokurovedza maultrasound dzokune dzimwe nyika, kunyanya dziya dzakabva kuUnited States, akawana mibvunzo yakawanda yebvunzo dzeultrasound yebasa rokuNorth America nenzira dzakasiyana-siyana.Mubvunzo mupfupi wemhinduro wakabvunzwa: Ndeupi musiyano pakati peCOLORULTRASONOGRAPHYuye COLOR DOPPLER ULTRASONOGRAPHY?
Ndeupi musiyano uripo pakati pemavara e ultrasound imaging uye ruvara Doppler ultrasound imaging?
Pakangopinda muChina ruvara rweDoppler ultrasound imaging, yakanzi "color ultrasound".Vanachiremba veChinese ultrasound vakagara vachienzanisa color ultrasound neruvara Doppler ultrasound, saka China yakaona dambudziko iri kekutanga.Vana chiremba vakaratidza kuvhiringika vakashaya kuti mubvunzo uyu waive wei.
Chaizvoizvo, uyu mubvunzo wakapfava.
Colour ultrasound inoreva kutaridza chiratidzo cheruzivo rwe echo panguva yekuongororwa kwe Ultrasound nemitemo yakakosha yekukodha, inova color ultrasound imaging.Aya chaiwo echo ruzivo anogona kuve echo intensity, Doppler frequency shift, kuoma ruzivo, microbubble ruzivo, nezvimwe.
saka.Ruvara Doppler kufungidzira ingori imwe chete yeakawanda mavara ekufungidzira modhi.Iyo inobvisa iyo Doppler frequency shift data kubva kune echo ruzivo uye inoiratidza muchimiro chemavara coding.
Pamusoro peiyo color Doppler imaging yatinoziva nayo, ngatitarisei mavara e ultrasound imaging modes.
Isu tinoziva kuti maviri-dimensional grey-scale ultrasound inoratidza kusimba kweiyo echo chiratidzo muchimiro chekupenya encoding.Kana tikaisa mavara-code pane imwe nzvimbo kana kupenya kwese, tinowana mufananidzo wakanyorwa-mavara.
Pamusoro: Nzvimbo chaiyo muchiratidzo che grayscale inoiswa muruvara rwepepuru (yakavhurika museve), uye ronda rine kupenya kunoenderana nepepuru (inoratidzwa nemuseve wakasimba).
Iyo nzira yekufungidzira iri pamusoro inoisa echo kusimba muruvara kana akasiyana mavara mazinga yaive yakakurumbira muChina kwenguva yakati mukutanga kwema1990.Yakanzi "2Dpseudo-ruvaraimaging" panguva iyoyo. Kunyange zvazvo mapepa akawanda akabudiswa panguva iyoyo, chaizvoizvo Iko kukosha kwekushandisa kwakanyanyisa. Panguva iyoyo, zvipatara zvakawanda zvakatoshandisa mufananidzo uyu kuti upfuure seruvara rweDoppler imaging kubhadharisa varwere "mari ye ultrasound". Kwaive kusanyara chaiko.
Muchokwadi, ese masaini emavara paruvara ultrasound imaging ndeye pseudo-mavara, uye aya masaini emavara akadhindwa kodhi uye akaiswa nesu.
Vazhinji vagadziri veultrasonic elastography, iyo ikozvino yakakurumbira zvikuru, inoratidzawo kuoma (kana elastic modulus) yetishu kana maronda mumhando yemavara-coded, saka ihwowo rudzi rwemavara e ultrasound.
Pamusoro: Shear wave elastography inoratidza elastic modulus yechironda mune ruvara chiyero coding.
Kana huwandu hushoma hwema microbubbles hunoputika, simba risingasviki rinogadzirwa richagadzirwa, iro rinowanzove risina kuwirirana zvakanaka ne echo intensity.Isu tinodaidza iyi nzira yekuburitsa ruzivo rusina-hukama rwekufungidzira kusiri-kukochekera imaging.Non-correlation imaging inonyanya kushandiswa kutaridza zvidiki-diki zvema microbubbles uye inobatsira zvakanyanya mu microbubble-targeted ultrasound research.Kazhinji, iyi isiri-yekubatanidza inoratidzwawo mune yemavara-coded fomu, saka zvakare iri ruvara rwekufungidzira.
Pamusoro: p-selectin microbubble-targeted imaging inoratidza kukwidziridzwa kweanterior wall mushure me ischemia, uye myocardial kusiyana-enhanced sonographic cardiac short-axis mifananidzo iri kuruboshwe anterior ichidzika ischemia-reperfusion mumakonzo.
(A) Myocardial kusiyana-enhanced ultrasound inoratidza anterior perfusion defect (museve) panguva yemyocardial ischemia.
(B) Mushure memaminitsi makumi mana nemashanu ekudzoreredza.Chikero cheruvara chinomiririra kusimba kwekufungidzira kusiri-kubatanidzwa kwemakrobubhu akatariswa.
Iko kuyerera kweropa vector imaging pazasi zvakare iri color ultrasound imaging mode
