SSFP simulation
Project description
SSFP
Simple steady-state free precession simulation. The goal is to provide a simple to use, pip-installable solution for simulating this wonderful pulse sequence.
In this package:
bSSFP: bssfp()
Installation
Should be as easy as:
pip install ssfp
Usage
See ssfp.examples for typical usage. You can run examples like:
python -m ssfp.examples.basic_bssfp
Balanced steady-state free precession can be called through bssfp(). This is an implementation of equations [1–2] in [1]. These equations are based on the Ernst-Anderson derivation [2] where off-resonance is assumed to be subtracted as opposed to added (as in the Freeman-Hill derivation [3]). Hoff actually gets Mx and My flipped in the paper, so we fix that here. We also assume that the field map will be provided given the Freeman-Hill convention.
from ssfp import bssfp
# Here's the simplest usage, see docstring for all the possible
# function arguments
sig = bssfp(T1, T2, TR, alpha)
