摘要

具有快速旋转机架的现代多层螺旋CT系统特别适合于心脏容积成像。由于锥角，与2D技术相比，真正的3D反向投影算法提供了更好的图像质量。我们提出了一种真正的锥束重建算法，利用最大量的测量数据，结合回顾性心脏门控。结果呈现在患者数据集上，该数据集已使用16层CT系统获得。

Aperture weighted cardiac cone-beam reconstruction using retrospective ECG gating

Modern multislice CT systems with a fast rotating gantry are particularly suitable for cardiac volume imaging. Due to the cone angle, true 3D back-projection algorithms deliver superior image quality compared with 2D techniques. We propose a true cone-beam reconstruction algorithm making use of the maximum amount of the measured data in combination with retrospective cardiac gating. Results are presented on a patient data set, which has been acquired using a 16-slice CT system.
