Hello all,
I met a problem in converting dicom to analyze.
The voxel size in my experiment is 3.125*3.125*6mm. I am using SPM2 to to
this conversion. After that, the M variable in *.mat is like
M =
3.1250 0 0 -103.1250
0 2.8766 -2.3444 -95.9544
0 1.2210 5.5230 -76.7248
0 0 0 1.0000,
and vox in *.hdr is like
vox =
3.1250 3.1250 6.0000.
In my understanding, the M(1,1)=M(2,2)=3.125 and M(3,3)=6 should be the
case. Otherwise, the voxels will be overlapped. Ex. vox1 in image [1 1 1]
will be [-100.0000 -95.4222 -69.9808] in mm and vox2 in image [1 1 2]
will be [-100.0000 -97.7666 -64.4577]. The problem is -69.9808+6 not
equal -64.4577.
Thanks.
