研究目的:

ASIR-V迭代重建技术能够很好的改善图像噪声,为了获得相同的图像质量,考虑结合低剂量联合能谱和ASIR-V迭代重建技术进一步降低缺血性脑卒中CT扫描的辐射剂量。  

Objectives of Study:

ASIR-V iterative reconstruction technology can improve the image noise very well. In order to obtain the same image quality, consider combining low-dose combined energy spectrum and ASIR-V iterative reconstruction technology to further reduce the radiation dose of CT scan of ischemic stroke.
