Lub npe tag nrho ntawm DSA yog Digital Subtraction Angiography, uas yog cov thev naus laus zis thev naus laus zis raws li cov duab sib txuas.Los ntawm kev rho tawm ob lub thav duab ntawm tib lub cev ntawm tib neeg lub cev, qhov sib txawv yog tau, thiab cov pob txha thiab cov ntaub so ntswg raug tshem tawm.Cov hlab ntsha uas muaj tus neeg sawv cev zoo sib xws hauv ob lub thav duab yog pom hauv daim duab rho tawm, txhim kho qhov sib txawv.Raws li kev kho mob duab thev naus laus zis uas tau tshwm sim tom qab CT hauv xyoo 1980s, DSA yog qhov tseem ceeb hauv kev kuaj mob ntawm cov kab mob vascular thiab yog txoj hauv kev tshawb pom zoo tshaj plaws hauv kev kuaj mob thiab kho cov kab mob plawv thiab cerebrovascular.tus "gold standard".Cov khoom siv digital rho tawm angiography, tseem hu ua DSA cov cuab yeej, tsis yog tsuas yog cov cuab yeej tshuaj xyuas, tab sis kuj yog cov cuab yeej saib xyuas tsim nyog hauv kev siv cov kev phais phais.
DSA cov cuab yeej yog tsim los ntawm X-ray generating ntaus ntawv, digital imaging system, mechanical system, computer control system, image processing system thiab auxiliary system (high pressure injector).Cov cuab yeej loj loj DSA feem ntau siv cov khoom siv hluav taws xob tiaj tus ntsuas cov duab digital.
Lub Whale4343 series amorphous silicon ca vaj huam sib luag ntes thiab Shark4343 series IGZO tiaj vaj huam sib luag detectors ntawm nws tus kheej tsim thiab tsim los ntawm Haobo muaj cov yam ntxwv ntawm cov duab zoo, ceev tau tus nqi, loj dynamic ntau yam thiab ntau yam ntawm daim ntawv thov davhlau ya nyob twg, uas yuav siv tau rau siab rhiab heev. daim ntawv thov.Nws tseem tuaj yeem ua tau raws li qhov xav tau ntawm qhov loj dynamic ntau yam scenes, thiab yog dav siv nyob rau hauv digital fluoroscopic photography, digital gastrointestinal tshuab, dynamic DR, digital silhouette DSA thiab lwm yam kev thov scenarios.
