Abstract

Subsecond multi-slice spiral CT has now been recognized with its great potential in cardiac imaging, in particularly for the coronary calcification detection (CCD). Different reconstruction algorithms have been developed in order to optimize the temporal resolution and to improve the measurement accuracy. These algorithms typically incorporate retrospectively gated reconstructions based on a synchronized electrocardiography (ECG) recording. However, these algorithms consist of different approaches in choosing spatial filters, setting ECG delays, and employing the reconstruction geometry (direct fan-beam vs. parallel rebining). These differences are likely to contribute to the intrascanner and interscanner variability in the coronary calcium measurements. This paper investigates in detail about the quantitative effect on calcium detection among different approaches.
