MRI PULSE SEQUENCE
DESIGN AND RECONSTRUCTION
If you publish results derived in part or whole from software obtained here, please acknowledge the MRI_UNBOUND website and the name of the code package that was used. If you publish results derived in part or whole from software obtained through one of the links, please acknowledge the linked site and author.
If you fix errors found in software from this site, or modify it in any substantial way that may be of benefit to others, please consider submitting those changes to this site by notifying the Project Manager. (ISMRM members only)
If you wish to submit your own software for pulse sequence design or image reconstruction, please contact the Project Manager. (ISMRM members only) Code can be in any language (C, Matlab, etc.) but it must be source code, not compiled (binary) code. It is understood that any submitted code may be freely used and distributed for research.
Code is bundled as a tar/zip file, whose name is the function, plus a unique 3-letter identifier (e.g. the author’s initials), and the date of submission (yymmm).
PULSE SEQUENCE DESIGN
Spiral Waveform Generation
- spiralgen_jgp_12oct is a support routine that numerically generates a single (variable density) spiral waveform, which may be rotated by the user for multi-shot spiral methods.
spiralgen_jgp_11apr (older version)
Sampling Density Calculation
sdc3_nrz_11aug.zip calculates the 3D sampling density weights
for an arbitrary set of sampling points - updated!
- grid3_dct_11aug.zip performs 3D gridding with an arbitrary coordinate set, data, and sampling density weights. The code is threaded, but can be altered slightly to run non-threaded if desired - updated!
- throughtimeRadialGrappa_nes_13oct.zip reconstructs undersampled radial data using through-time radial GRAPPA
