Dear Experts,
I have Phillips 3T aquired magnitude and field map images in DICOM format, with the questions below:
1. To BET the magnitude image, what parameters do you recommend? The standard ones, leave the skull inplace, likely secondary to the lack of contrast between scalp and brain in this image type.
2. My Field Map image is in Hz, what is the best way to find the appropriate converstion factor to render it in rad/s units?
3. In using the dcmniigui to convert the original field map dicom images, I have tried various iterations to which Nifti type to convert to with the results:
- FSL 4D Nii: one big file with the magnitude and Field Map dumped in
- SPM 3D Nii: two separate files not recognized by fsl programs (.img)
- 4D Nii/hdr: one big file but recognized by at least BET so far.
Any recommendations?
Thanks in advance,
Varina
