Spectral-Spatial RF Pulse Design for MRI and MRSI MATLAB Package Originally Written by: Adam B. Kerr and Peder E. Z. Larson
======================
This package includes Matlab functions to design spectral-spatial RF pulses (also known as spatial-spectral RF pulses) for application to magnetic resonance spectroscopy and imaging. See the "examples/" folder for sample code and pulse designs.
Examples include excitation and refocusing pulses, as well as pulses for hyperpolarized carbon-13 MRI.

Requirements:
- Signal Processing Toolbox (MathWorks)
- Optimization Toolbox (MathWorks)
- rf_tools package : This is included in the package, and also available for download at http://rsl.stanford.edu/research/software.html
