Many interventional procedures aim at changing soft tissue perfusion or blood flow. One problem at present is that soft tissue perfusion and its changes cannot be assessed in an interventional suite because cone‐beam computed tomography is too slow (it takes 4–10 s per volume scan). In order to address the problem, we propose a novel method called IPEN for Intra‐operative four‐dimensional soft tissue PErfusion using a standard x‐ray system with No gantry rotation.

使用没有机架旋转的标准X射线系统进行的基于三维感兴趣区域的术中三维软组织灌注成像：用于概念验证的模拟研究

许多介入程序旨在改变软组织灌注或血流。当前的一个问题是，由于锥束计算机断层扫描速度太慢（每次体积扫描需要4到10 s），因此无法在干预套件中评估软组织的灌注及其变化。为了解决这个问题，我们提出了一种称为IPEN新颖方法，用于我NTRA手术四维软组织PE使用与标准x射线系统rfusion Ñ ö机架旋转。
