Hi Leo: I have faced this problem before. Philips scanner's default output format is the PAR/REC format - but it also outputs in Dicom format. What I believe is the problem is that the images are oriented wrongly. Take a look at this in MRICRO and see how the images are oriented. You may need to reorient the images to be acceptable to FS.
hope this helps! Alan On Tue, Mar 15, 2011 at 4:01 PM, leonardo kay <leonardo....@gmail.com>wrote: > Hi All > > I'm new in freesurfer. I have a question regards Philips DICOM format.
