Danho 1:Zviridzwa zvezviridzwa
Rudzi Rwenhema: Ruvara rwakajeka (ruvara rwenhema) runogona kunatsiridza mutsauko nekusimudzira mutsauko wakapfava wakaoma-kune-kuona.Nechepfungwa, ziso remunhu rinongokwanisa kuona nhamba shoma yegrey mazinga, asi rinogona kuona huwandu hukuru hwemazinga emavara akasiyana.Naizvozvo, kushandura ruvara kunogona kuwedzera kuzivikanwa kwezvimiro zvinyoro zvinyoro.Pseudo-ruvara haichinji iyo yakaratidzwa ultrasound ruzivo, asi inongovandudza maonero eruzivo.
2D mufananidzo kugadzirisa
Chinangwa chekugadzirisa iyo-maviri-dimensional mufananidzo ndeyekusiyanisa myocardial tishu uye yemwoyo dziva reropa kusvika pamwero mukuru uchichengetedza yakakwirira furemu chiyero.Iyo yakakwirira iyo furemu chiyero, inotsvedzerera iyo mufananidzo kuratidza uye neruzivo rwakawanda rwaunogona kuwana.
Parameters inokanganisa furemu rate
Kudzika: Kudzika mufananidzo furemu mwero wemufananidzo.Iyo yakakura kudzika, iyo inotora nguva yakareba kuti chiratidzo chidzoke kune probe, uye kudzika kweiyo furemu rate.
Upamhi: Kukura kwehupamhi hwemufananidzo, iyo sparser yemunharaunda sampling line density, uye yakaderera chiyero chefuremu.Image zoom (zoom): Iyo zoom function yenzvimbo inofarira ndeyekukosha kukuru pakuongororwa kwezvimiro zvidiki uye zvimiro zvinofamba nekukurumidza, senge morphology yemavharuvhu.
Line density: Iyo yakanyanya scan mutsara weimwe neimwe furemu yemufananidzo ndiyo density yemutsara.
Maviri-dimensional mufananidzo optimization nzira
Harmonic imaging (harmonics): Nekuda kwekupindira kwakasimba kweparutivi-lobe yendima yakakosha yekurira uye kukanganiswa kusingaite kweparutivi-lobe kwenzvimbo inonzwika yeharmonic, zita remufananidzo unogadzirwa nekushandisa ruzivo rwemuviri wemunhu rwakatakurwa nerechipiri. harmonic mu echo (reflection kana kuparadzira) For ultrasound harmonic imaging.
Multi-domain composite imaging (XBeam): Kugadziriswa kwemifananidzo inoumbwa mune frequency domain uye spatial domain inogona kubvisa zvinokonzeresa mhedzisiro yekuderedzwa kwekugadzirisa kwenzvimbo kunokonzerwa neiyo image discretization uye mufananidzo attenuation, uye kugadzirisa kushaikwa kwekugadziriswa kwenzvimbo yemufananidzo wekutanga. .Wana mufananidzo wakajeka.
Step2: Kugadziriswa kwemavara, simba uye yakakwirira-resolution simba Doppler
Nekuti mifananidzo yemhando yepamusoro inonyanya kuratidza
1. Saizi yemufananidzo iri pakati nepakati
2. Mufananidzo wacho une chiedza chakakodzera uye mumvuri
3. Kusiyanisa kwakanaka kwemufananidzo uye kugadziriswa kwepamusoro
4. Kufanana kwemufananidzo wakanaka
5. Wedzera kunzwisisika kwemavara uye kuratidza kuderera-kuyerera kweropa
6. Deredza kuyerera kwemavara uye bvisa aliasing
7. Wedzera furemu chiyero (tora high-speed blood flow signals)
8. Wedzera kunzwisiswa kwePW&CW
Main menu settings
Gain control: Kana iyo color gain setting yakadzikira, zvichanetsa kuratidza masaini emavara.Kana marongero akanyanya kukwirisa, ruvara rwekuyerera uye aliasing zvichaitika.
Kusefa kwemadziro: Kunobvisa ruzha rwunokonzerwa netsinga yeropa kana kufamba kwemadziro emwoyo.Kana sefa yemudhuri yakadzikira zvakanyanya, mavara anobuda ropa.Kana kuseta kwesefa yemudhuri kwakakwira zvakanyanya uye nhanho yekumhanya ikagadziriswa yakakurisa, zvinokonzeresa kushata kwekuyerera kweropa.Kuti uratidze kuderera-kumhanya kweropa, nhanho yekumhanya inofanira kuderedzwa zvakakodzera kuti ienderane nekuonekwa kwekuyerera kweropa, kuitira kuti kubuda kweropa kwemavara kunogona kuratidzwa zvakakwana.
Sub menyu marongero
Mepu yemavara: Imwe neimwe yeari pamusoro pemavara mepu kuratidza modhi ine sarudzo kubva pasi kusvika kumusoro, uchishandisa mavara akasiyana kuratidza akasiyana ekuyerera kweropa.
Kakawanda: Pane zvitatu zvingasarudzwa: kumusoro, pakati uye pasi.Pamafandemutande epamusoro, kumhanya kunokwanisa kuyerwa kwakadzikira uye kudzika hakuna kudzika.Pamafafitera akaderera, kumhanya kunokwanisa kuyerwa kwakakwira uye kudzika kwakadzika.Iyo yepakati frequency pane imwe nzvimbo pakati.
Ropa rinoyerera (flowresolution): Pane zvingasarudzwa zviviri: kumusoro uye pasi.Imwe neimwe sarudzo ine sarudzo dzinoverengeka kubva pasi kusvika kumusoro.Kana kuyerera kweropa kukadzikira, mapikseli eruvara achange akakura.Kana yaiswa kumusoro, mapikisi emavara madiki.
Speed scale (chiyero): Pane kHz, cm/sec, uye m/sec sarudzo.Kazhinji sarudza cm/sec.Chiyero: Dzora masaini emavara akaiswa pamusoro peiyo-maviri-dimensional ultrasound mufananidzo kuitira kuti mavara masaini anongoratidzwa mukati memadziro etsinga pasina kupera.Iro sarudzo yemhando ndeye 1 ~ 225.
Kutsvedza: Inopfavisa mavara kuita kuti chifananidzo chitaridzike chakapfava.Shandisa sarudzo mbiri, RISE uye FALL, kuti uwane chiyero.Imwe neimwe sarudzo ine sarudzo dzinoverengeka kubva pasi kusvika kumusoro.
Line density: Kana mutsetse wemutsara ukawedzera, chiyero chechimiro chinodzikira, asi ruzivo rwuri muvara Doppler runowedzera, uye miganhu pakati pemoyo dziva reropa, ventricular madziro, uye interventricular septum inova yakajeka.Paunenge uchiseta, unofanirwa kuenzanisa hukama pakati pemutsara density uye frequency, uye edza kuwana yakakwira mutsara density pane inogamuchirwa furemu chiyero.
Artifact kudzvanywa: Kazhinji inosarudzwa kuti isavepo.
Rudzi rwekutanga: Fambisa zero mutsara weruvara Doppler kumusoro uye pasi kuti ubvise kana kuderedza kukanganiswa kwemavara kuitira kuti ruvara rweDoppler runyatso kuratidza mamiriro ekuyerera kweropa.
Mutsara sefa: Kuti uwane chiyero pakati pe lateral resolution uye ruzha rwemufananidzo, unogona kusarudza nhamba yema lateral mafirita, ane sarudzo dzakasiyana kubva pasi kusvika kumusoro.\
Routine Ultrasound Kugadziriswa---2D, CDFI, PW, nezvimwe.
1.2D Kugadziriswa
1.1 2D inogara ichigadzirisa zvemukati
1.2
2D Zvisiri zvinogara zvichigadziriswa zvemukati
Kudzika:
Shandisa ma-low-frequency probes kana maronda emutezo akakura
Basa rekusimudzira mufananidzo (kuverenga nekunyora kukura) rinoratidza zvimiro zvidiki uye inovandudza kuyerwa kwechiyero.
Basa rekusimudzira mufananidzo (kuverenga nekunyora kukura) rinoratidza zvimiro zvidiki uye inovandudza kuyerwa kwechiyero.
Chiedza chemufananidzo uye mumvuri wakakodzera kuwana GAIN---inogadzirisa amplitude yekuratidzira yeese masaini anogamuchirwa, inokanganisa kupenya kweiyo ultrasound kuratidza.
Yakanyanya hypoechoic maronda anowedzera kuwanda kwese kudzivirira kusazivikanwa se cystic maronda
Kudzika kuwana muripo DGC inogadzirisa kunyura uye kudzoreredza maitiro emafungu e ultrasonic kana achipararira mumuviri wemunhu, ayo anoburitsa maungira akasimba mumunda wepedyo uye maungira asina simba mumunda uri kure.Rongedza zvakakodzera iyo DGC kudzvanyirira munda uri padyo uye kutsiva iyo iri kure munda, kuti iyo echo yemufananidzo iite Uniform.
