ASPIRE / MCPC-3D-S for MATLAB

MRI phase combination algorithm for combining channels of array-coils

ASPIRE requires 2 * TE1 = TE2

Other versions

• compiled MCPC-3D-S (no MATLAB required)
• MCPC-3D-S written in julia

Patent

There is a patent on ASPIRE and a license is required for commercial use. However, it is not a medical product, which means that the method may not be used for diagnosis in humans.

For scientific purposes no licence is required and the method can be applied free of charge.

Installation

Clone the repository with git or download as ZIP file.

Configuration

Set the data location and parameters in aspire_custom.m
Uncombined magnitude and phase images are required as NIfTI files.
The dimensions of the input NIfTI files have to be [x, y, z, echo, channel].

Run ASPIRE

Start aspire_custom.m

Additional Requirements

For the slice_by_slice option (low memory usage), fslmerge is required.

Advanced

Experimental stuff is shared in the folder kFiles
