Hello,
I'm currently looking to segment some CT data with the Dragonfly software. However, the reconstructed data I received is in the .vol file format, which I cannot import/open with all the segmentation programs I use. I am now looking for a program to slice up the .vol files into .TIFF files and start my segmentation from there. Does anyone know a way to convert .vol files like that? Or is anyone aware of freeware to segment .vol files?
Most likely, the .vol file is just a binary array. For correctly interpreting it, you would need some meta-information, e.g. dimensions in x, y, z, the voxel-size, the data-type (e.g. 16bit-unsigned-int, 32bit-float, ...), and the "endianess", i.e. "little endian" or "big endian".
The CT reconstruction-software should provide a separate file containing that information, or even a wrapper for direct import.
In many applications you can import the .vol-file as "raw" image, where you have to specify the necessary meta-information.
For conversion from raw to TIFF you could, for instance, use Fiji/ImageJ.
I'd also try it in Fiji/ImageJ too as suggested.
Is the data from a microCT/ultrasound scanner or something? You should also be able to export in DICOM
I know a while back (maybe 2-3 years) it was perhaps being implemented into 3DSlicer as an extension, although I'm not sure if that was successful or not.
One example is here: https://discourse.slicer.org/t/vol-files-not-getting-loaded/8483
