  • Title: Simple analytic variable density spiral design.
    Author: Kim DH, Adalsteinsson E, Spielman DM.
    Journal: Magn Reson Med; 2003 Jul; 50(1):214-9. PubMed ID: 12815699.
    Abstract:
    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.
