ct projection data的意思|示意

It is an effective way for improving quality of reconstructed images that projection data are optimized in the field of Computerized Tomography (ct).

在计算机层析技术(CT)中，优化投影数据是改善重建图象质量的有效途径。

Now the existing direct volume CT methods face two difficulties:first, how to get the projection data to reconstruct the 3D image exactly, including whether the scanning structure is practical;

目前直接体积CT主要存在两大困难：一是如何获得三维图像精确重建所需的投影数据，包括扫描方式的可实现性；
