Abstract

This extension of our previous work on tomographic digital subtraction angiography (DSA) describes the theory of tomosynthetic DSA image reconstruction techniques. In addition to developing the resolution limits resulting from x-ray exposure length and image intensifier field curvature, we describe one method of image formation and show tomosynthetic DSA images of animal and human anatomy. Methods for improving the present technique are discussed.

摘要

我们先前关于断层数字减影血管造影（DSA）的工作扩展，描述了断层合成DSA图像重建技术的理论。除了研究因X射线曝光长度和图像增强器场曲率导致的分辨率限制外，我们还描述了一种图像形成方法，并展示了动物和人体解剖结构的断层合成DSA图像。文中还讨论了改进当前技术的方法。
