Toolbox: Gradient Waveform design.


Download: toolbox_gradient_waveform_design.zip
Tooblox relative to the paper A projection algorithm for gradient waveforms design in Magnetic Resonance Imaging (pdf). Given any input trajectory, our code returns an admissible curve and the gradient to traverse it that fulfills the MRI constraints (maximal intensity and slew rate). It is possible to add affine constraints, such as initial and final k-space position, gradient moment nulling, etc... Examples: Please report any bug or remark to: nicolas.chauffert@gmail.com.

CS-MRI simulator


(Cartesian framework)
Code relative to the paper: Variable density sampling with continuous trajectories. Application to MRI. (pdf)
This code (in Matlab) contains scripts to design continuous sampling schemes (e.g., based on Travelling Salesman Problem), and to perform reconstruction for MRI simulations.
