Docket #: S07-004
MRI - A Fast Method for Designing Time-Optimal Gradient Waveforms for Arbitrary k-Space Trajectories
A method for magnetic resonance imaging (MRI) is provided. A scanning path is specified. Gradient amplitude is determined as a function of arc-length along the scanning path in k-space. A time optimal gradient waveform for scanning the scanning path is calculated from the gradient amplitude. The scanning path is scanned using the time optimal gradient waveform.
Applications
- optimized for each scan plane geometry, on the fly in real time applications.
