Dear All,
I have some (less than ideal) MRI structural images that I want to
co-register with PET data. When I display them in SPM2 it is reporting
the following:
Dimensions: 512x512x130 (correct)
Datatype: int16 (correct)
Intensity: Y=1X (correct)
Vox size: -0.449 x 0.449 x 1.39 (correct)
Origin: 1.8e+04 1.77e+04 1.72e+04 (strange)
Dir Cos: 1.000 0.000 0.000
0.000 0.540 -0.841
0.000 0.841 0.540
The images were acquired approximately coronally, so I re-orient by a
ptich rotation of approx -pi/2 before I did this display.
If I click on the image and get the crossharis to about were I would
like the origin to be the display window reports the crosshair position as:
mm: 7973.1 15786.8 -19443.1
vx: 253.2 309.1 60.0
It seems to me that SPM2 is not handling the voxel to world translation
correctly. Can anyone help?
Many thanks,
Mark
