Imaging Toolkit
Fast Imaging Library
This library of functions provides a number of algorithms to reconstruct accelerated MR data, including
- UNFOLD
- Parallel Imaging Methods
- SENSE, Variable Density SENSE, regularized SPACE RIP, and GRAPPA
as well as a number of associated MR image reconstruction algorithms, including
- Homodyne processing of partial-Fourier data
- Gradient field inhomogeneity correction (gradwarp)
- Nyquist Ghost correction
The complete package includes a reference manual (PDF and HTML), a binary library file, and demos in both C and Matlab (via MEX). To get started, follow the "Quick Start Guide" given in the manual.

Change Log:
- OF NOTE: changed name of 'COORD' struct to 'XCOORD', for Siemens ICE compatibility
- cleaned up win32 compiler warnings
- added Nyquist Ghost Elimination via Spatial and Temporal Encoding (GESTE) functions
- added display demo for showing images of .nd data in Windows
- fixed memory leak in find_tag (DICOM util)
- added fft manager init check to catch segfaults on uninitialized buffers
- split GRAPPA reconstruction code into two parts, so that GRAPPA reconstruction parameters can now be easily reused.
- fixed a bug in the project_mask function, so that it now works with rectangular matrices

Change Log:
- added functions to support phase alignment between images
- added functions to support virtual body coil estimation
- converted CWP SVD code to use double precision. Fixed bug that prevented economy-sized SVD.
- added code for fast left-singular-vector calcuation (lsv) useful for rank-1 estimation of matrices
- fixed malloc bug in correct_rampsamp function
- converted unfold_filter to use multiple threads
- additional C-code demos added
