[Insight-users] extracting a subvolume from a larger volume

[shoosh moosh]

I don't want to resample the entire image. I want to crop out a certain subvolume from the whole image with this subvolume having a defined origin with respect to the original image, and defined dimensions that are actually smaller than the original image. The orientation of the smaller subvolume with respect to the original image is also a given.

Thanks

Hi,

Look at the ResampleImageFilter and remember to set the transform and interpolation method along with the output information such as size, spacing and origin.

Instead,the inputs would be the origin, the dimensions of the subvolume, and the subvolume orientation information.
