I guess he was asking for code to read the kspace raw data. If so, that is
not fun at all since there are many kinds of different labels in the rawdata
header. After reading the data, he will need to do gridding for rampup
sampling and then phase correction, and FFT. But just a quick clue. For
fMRI, it's not that hard to read the ksp data. The basic organization is:
each volume contains several slices; each slice contains 3 reference lines
ky lines with altered directions (means left to right for odd lines and
right to left for even lines); each line contains a header and the complex
values of 2*kx points (so it's actually 4 x kx double floating point data).

Why don't you use DICOM import function of SPM5?

It works for me and we have the same MR-system.

I guess you get them as DICOMS? If so try MRIConvert from the University
of Oregon to convert them to Analyze/SPM-readable format.

Hope this helps,
