Q: Converting DICOM images to Analyze or Raw format
Images downloaded from the Data Registry will most likely be in the DICOM
format. If you wish to save these images in the Analyze (AVW) format or
in Raw format (no header info.) do the following: There are two ways for
you to save images from the Registry (which are in DICOM) format to disk
space in the Analyze (AVW) format or Raw format.
You can load a study directly into MEDx by using the "Open from Registry"
option under the Image menu in the MEDx folder. After the study is loaded
into MEDx, you can view a desired volume and use the Save Image As option
to save the volume in the AVW format. The Save Image As option is found
under the Image menu. Be sure to go into 3D mode from the Toolbox so that
you do not save one slice from the volume.
If you already have saved the DICOM files to afs space, there is a script
that you can use to convert images in a series from DICOM format to AVW
format. The script is called f_c and resides in the following directory:
/afs/alw.nih.gov/od/MRIPS/bin You should run this script from the sub-file
directory containing the images to be converted. There will be an option
for you to place an Analyze header on the image if you choose to.
