Dzina lonse la DSA ndi Digital Subtraction Angiography, lomwe ndi ukadaulo wochotsa digito kutengera zithunzi zotsatizana.Pochotsa mafelemu awiri azithunzi za gawo lomwelo la thupi la munthu, gawo losiyana limapezeka, ndipo mafupa ndi minofu yofewa imachotsedwa.Mitsempha yamagazi yodzazidwa ndi chosiyanitsa mu mafelemu awiriwa ikuwonetsedwa pachithunzi chochotsa, kukulitsa kusiyanitsa.Monga luso lojambula zithunzi zachipatala lomwe linatuluka pambuyo pa CT m'zaka za m'ma 1980, DSA ndi yofunika kwambiri pakuzindikiritsa matenda a mitsempha ya mitsempha ndipo ndiyo njira yodziwika bwino yodziwira matenda ndi chithandizo cha matenda a mtima ndi cerebrovascular."Gold standard".Digital subtraction angiography system, yomwe imadziwikanso kuti zida za DSA, sikuti ndi zida zowunikira zokha, komanso zida zowunikira zofunikira pakukhazikitsa opaleshoni yolowera.
Zipangizo za DSA zimapangidwa makamaka ndi zida zopangira X-ray, makina ojambulira digito, makina amakina, makina owongolera makompyuta, makina opangira zithunzi ndi makina othandizira (injector yothamanga kwambiri).Zida zazikulu za DSA nthawi zambiri zimagwiritsa ntchito makina ojambulira a digito.
Whale4343 mndandanda wa amorphous silicon flat panel detectors ndi Shark4343 mndandanda wa IGZO flat panel detectors paokha opangidwa ndi Haobo ali ndi mawonekedwe apamwamba kwambiri azithunzi, kutsika kwachangu, mitundu yayikulu yosinthika ndi mitundu ingapo yamapulogalamu, omwe angagwiritsidwe ntchito kukhudzika kwakukulu. mapulogalamu.Itha kukwaniritsanso zosowa zamawonekedwe akuluakulu osiyanasiyana, ndipo imagwiritsidwa ntchito kwambiri pazithunzi za digito za fluoroscopic, makina am'mimba a digito, DR yamphamvu, silhouette ya digito DSA ndi zochitika zina zogwiritsira ntchito.
