Tekinoroji itsva yejekiseni re CT, MRIuyeAngiographymasisitimu anobatsira kuderedza dose uye anonyora otomatiki musiyano wakashandiswa pakunyora murwere.
Munguva pfupi yapfuura, zvipatara zvakawanda zvakabudirira kuderedza mitengo nekushandisa majekiseni ekudzivirira kusiyanisa mavara akagadzirwa netekinoroji yepamusoro mukuderedza marara ekuenzanisa mavara uye kuunganidza data otomatiki yemushonga unogamuchirwa nemurwere.
Kutanga, ngatitorei maminitsi akati wandei kuti tidzidze nezve contrast media.
Chii chinonzi contrast media?
Contrast media chinhu chinopinzwa mumuviri kuti chiwedzere musiyano uripo pakati penyama dzemuviri pamifananidzo. Contrast medium yakakodzera inofanira kuwana huwandu hwakawanda munyama pasina kukonzera migumisiro yakaipa.
Mhando dzeContrast Media
Iodine, chicherwa chinotorwa kubva muvhu, matombo nemunyu, chinowanzoshandiswa mumifananidzo yekuenzanisa (contrast media) paCT neX-ray. Michina yekuenzanisa (lodinated contrast media) ndiyo inonyanya kushandiswa, CT ichida huwandu hwakawanda. Michina yese yekuenzanisa inoshandiswa pari zvino yakagadzirwa kubva patriiodinated benzene ring. Kunyange zvazvo atomu yeiodine iri iyo inokonzera radiopacity yemichina yekuenzanisa (contrast media), iyo organic carrier ndiyo ine basa rezvimwe zvinhu zvayo, zvakaita se osmolality, tonicity, hydrophilicity, uye viscosity. Iyo organic carrier ndiyo ine basa remigumisiro yakawanda yakaipa uye yakagamuchirwa zvakanyanya nevaongorori. Vamwe varwere vanopindura kune michina midiki yekuenzanisa (contrast media), asi mizhinji yemigumisiro yakaipa inokonzerwa ne large osmotic load. Saka, mumakumi emakore apfuura vaongorori vakatarisa pakugadzira michina yekuenzanisa (contrast media) inoderedza osmotic load mushure mekushandisa michina yekuenzanisa (contrast agents).
Chii chinonzi contrast media injectors?
Majekiseni ekudzivirira kupatsanurana (contrast injectors) zvishandiso zvekurapa zvinoshandiswa pakupinza majekiseni ekudzivirira kupatsanurana mumuviri kuti zviwedzere kuonekwa kwematishu ekurapa. (Tora jekiseni reCT double head high pressure semuenzaniso, ona mufananidzo uri pazasi:)
Maitiro e tekinoroji nyowani mujekiseni rekumanikidza kwakanyanyainobatsira kuderedza kutambisa contrast media panguva yekubaiwa jekiseni?
1. Masisitimu eInjector eOtomatiki
Masisitimu ekuisa majekiseni otomatiki anogona kudzora huwandu hwemhando yemhando yemhando ye "contrast" inoshandiswa, izvo zvinopa mikana mitsva kumadhipatimendi e "radiology" ari kutsvaga kugadzirisa nekunyora mashandisirwo aanoitwa ne "contrast media". Nekufambira mberi kwetekinoroji,majekiseni ekumanikidza zvakanyanyazvakashanduka kubva pakushandisa majekiseni ari nyore emaoko kuenda kumasisitimu ega ega asingangotungamiriri chete huwandu hwemushonga wekuenzanisa unoshandiswa, asiwo anorerutsira kuunganidzwa kwedata otomatiki uye madosi akagadzirirwa murwere wega wega.
LnkMedyakagadzira majekiseni chaiwo ekudzivirira kukuvara kwemutsinga muComputed Tomography (CT) uye Magnetic Resonance Imaging (MRI) uye kune maitiro emukati metsinga mukurapa kwemwoyo nekunze. Mhando dzese idzi ina dzemajekiseni dzinobvumira jekiseni otomatiki. Kune mamwe mabasa e otomatiki akagadzirirwa kurerutsa mashandiro evashandi vehutano uye kuwedzera kuchengetedzeka, akadai sekuzadza otomatiki uye priming, kufambisa otomatiki uye kudzosera shure kana uchibatanidza uye kubvisa sirinji. Kunyatsojeka kwevhoriyamu kunogona kudzikira kusvika ku0.1mL, zvichiita kuti ive nedosi chaiyo yejekiseni repakati rekuenzanisa.
2. Majekiseni Asina Sirinji
Majekiseni esimba asina sirinji abuda semhinduro yekuderedza marara e contrast media. Sarudzo iyi inopa zvivakwa mukana wekushandisa contrast media zvinobudirira sezvinobvira. Muna Kurume 2014, Guerbet yakatanga FlowSens, sisitimu yayo yekuisa jekiseni isina sirinji ine injector yesoftbag uye zvinhu zvinoraswa zvinoenderana nayo, ichishandisa hydraulic, isina sirinji injector kuendesa contrast media；Majekiseni matsva eBracco e "smart" Empower syringless anokwanisa kushandisa donhwe rega rega re contrast rakaiswa musystem kuti rive nehupfumi hwakanyanya. Kusvika pari zvino, dhizaini yavo yakaratidza kuti majekiseni esimba asina sirinji aive nyore kushandisa uye anoshanda kupfuura dual-syringe power injector, uye marara akawanda pa CT imwe neimwe inowedzerwa contrast yakaonekwa kune yekupedzisira. Injector isina sirinji yakabvumirawo kuchengetedza mari inosvika $8 pamurwere kana tichifunga nezvemutengo wakaderera uye kushanda kuri nani kwemidziyo.
Semutengesi,LnkMedinoita kuti kuchengetedza mari yevatengi vayo kuve chinhu chinonyanya kukosha. Takazvipira kugadzira zvigadzirwa zvinoshanda, zvakachengeteka uye zvisingadhuri kuburikidza nehunyanzvi hwetekinoroji kuti tichengetedze mari yevatengi vedu.
