ʻO ka inoa piha o DSA ʻo Digital Subtraction Angiography, kahi ʻenehana unuhi kikohoʻe e pili ana i nā kiʻi kaʻina.Ma ka unuhi ʻana i ʻelua papa o nā kiʻi o ka ʻāpana like o ke kino kanaka, loaʻa ka ʻāpana ʻokoʻa, a hoʻopau ʻia ka iwi a me nā ʻiʻo palupalu.Hōʻike ʻia nā kīʻaha koko i hoʻopiha ʻia me ka mea hoʻohālikelike i loko o nā papa ʻelua i ke kiʻi unuhi, e hoʻonui ana i ka ʻokoʻa.Ma ke ʻano he ʻenehana kiʻi lāʻau lapaʻau i puka mai ma hope o CT i ka 1980s, he mea koʻikoʻi ka DSA i ka hōʻoia ʻana o nā maʻi vascular a ʻo ia ke ala ʻike maikaʻi loa i ka ʻike interventional a me ka mālama ʻana i nā maʻi cardiovascular a me ka cerebrovascular.ka "pae gula".ʻO ka ʻōnaehana angiography hōʻemi kikohoʻe, ʻike ʻia hoʻi ʻo DSA lako, ʻaʻole ia he mea nānā wale nō, akā he mea pono no ka nānā ʻana i ka hoʻokō ʻana i ke ʻoki interventional.
ʻO nā lako DSA ka mea nui i haku ʻia me ka X-ray generating device, digital imaging system, mechanical system, computer control system, image processing system and auxiliary system (high pressure injector).Hoʻohana maʻamau nā lako DSA nui-nui i ka ʻōnaehana kiʻi kiʻi kiʻi palahalaha-panel detector.
ʻO ka Whale4343 series amorphous silicon flat panel detectors a me Shark4343 series IGZO flat panel detectors i hoʻomohala kūʻokoʻa a hoʻolālā ʻia e Haobo i nā hiʻohiʻona o ke kiʻi kiʻi kiʻekiʻe, ka wikiwiki o ka loaʻa ʻana, ka laulā nui a me ka laulā o nā noi terminal, hiki ke hoʻopili ʻia i ka ʻike kiʻekiʻe. nā noi.Hiki iā ia ke hoʻokō i nā pono o nā hiʻohiʻona nui dynamic, a hoʻohana nui ʻia i nā kiʻi fluoroscopic kiʻi kiʻi, mīkini gastrointestinal digital, DR dynamic, digital silhouette DSA a me nā hiʻohiʻona noiʻi ʻē aʻe.
