The ideal variable velocity scanning mode in cardiac computed tomographic imaging

摘要

In this article, a new kind of mode for ideal variable velocity scanning for computed tomography is proposed. First, smoothed transition model of variable velocity and the ideal scanning velocity are presented in multiple heart cycles scanning. Second, the mechanical property and the feasibility for variable velocity scanning are analyzed. Last, cardiac motion mode is designed, and the image is reconstructed by the computed tomography reconstruction algorithm to verify the variable velocity scanning model.
