DSA的參考例句
1.Because of the had definition of images in using DSA machine, the X-ray detector was used to check the DSA output dose so as to solve the image quality problems. 在機器使用過程中發現圖像清晰度不好，利用X射線機質量檢測儀檢測該機器的輸出劑量是否準確，為解決圖像質量問題提供依據。
2.Because of the complexity and non_linearity of the X_ray imaging process, the common DSA technique cannot completely remove other tissues image which lapped over the vessels. 由於X線成像過程的複雜性和非線性，普通的減影方法並不能完全消除與血管重疊的其它組織的影像。
3.CONCLUSIONS: As long as the CTA scan is of adequate quality and shows the aneurysm clearly, we consider that an additional DSA provides little useful information for surgery. 結論︰只要CTA掃瞄具有高質量圖像，能清楚地顯示動脈瘤，我們認為補充的DSA能為手術提供少許有用信息；
