Igama eligcwele le-DSA i-Digital Subtraction Angiography, okuwubuchwepheshe bokukhipha obudijithali obusekelwe ezithombeni ezilandelanayo.Ngokukhipha amafreyimu amabili ezithombe zengxenye efanayo yomzimba womuntu, ingxenye ehlukile iyatholakala, futhi izakhiwo zethambo nezicubu ezithambile ziyaqedwa.Imithambo yegazi egcwele i-ejenti ehlukile kumafreyimu amabili ibonakala esithombeni esikhiphayo, okuthuthukisa ukugqama.Njengobuchwepheshe be-imaging yezokwelapha obuvela ngemva kwe-CT ku-1980s, i-DSA ibaluleke kakhulu ekuxilongweni komtholampilo kwezifo ze-vascular futhi iyindlela ephumelela kakhulu yokuthola ekuxilongweni kokungenelela kanye nokwelashwa kwezifo zenhliziyo kanye ne-cerebrovascular."izinga legolide".I-Digital subtraction angiography system, eyaziwa nangokuthi imishini ye-DSA, ayiyona nje into yokuhlola kuphela, kodwa futhi iyimishini yokuqapha edingekayo ekusetshenzisweni kokuhlinzwa kokungenelela.
Imishini ye-DSA ikakhulukazi yakhiwe idivayisi ekhiqiza i-X-ray, isistimu ye-imaging yedijithali, isistimu yemishini, isistimu yokulawula ikhompuyutha, uhlelo lokucubungula izithombe kanye nesistimu eyisizayo (i-high pressure injector).Imishini emikhulu ye-DSA ngokuvamile isebenzisa isistimu yokuthwebula yedijithali yesitholi sephaneli eyisicaba.
I-Whale4343 series amorphous silicon flat panel detectors kanye ne-Shark4343 series IGZO flat panel detectors ezithuthukiswe ngokuzimela futhi zaklanywa u-Haobo zinezici zekhwalithi ephezulu yesithombe, izinga lokutholwa ngokushesha, ububanzi obukhulu obuguqukayo kanye nohlu olubanzi lwezinhlelo zokusebenza zetheminali, ezingasetshenziswa ekuzweleni okuphezulu. izicelo.Ingakwazi futhi ukuhlangabezana nezidingo zezigcawu ezinkulu eziguqukayo, futhi isetshenziswa kabanzi ezithombeni zedijithali ze-fluoroscopic, umshini we-digital gastrointestinal, i-DR eguquguqukayo, i-digital silhouette DSA nezinye izimo zohlelo lokusebenza.
