Simple analytic variable density spiral design
DOI:10.1002/mrm.10493.png)
摘要
En 中文
Variable density spirals have been proposed in a variety of applications, including MR fluoroscopy, cardiac imaging, and MR spectroscopic imaging. In this work, a simple analytic solution for designing a flexible set of variable density spiral trajectory waveforms is presented. The method enables real-time waveform prescription on scanners with limited computational power. Both slew rate-limited and amplitude-limited regimes are incorporated in the design process., (C) 2003 Wiley-Liss, Inc.
