Saving Volume Image Data



When saving an image either as a direct copy of an original dataset or a transformed version of a dataset, rview prompts for a file name:

save im vol


Currently rview can save an image volume in one of two file formats: Mayo Analyze format or UMDS GIPL (Guys image processing lab) format. The type is basically determined by the extension of the
file name (.hdr) forces analyze format to be used, while .gipl forces GIPL format to be used). Please note: both formats are saved in little endian (SUN) byte order to remain compatible with the original sun version of analyze. Both image formats store the data using 16 bit signed format for voxel values.
Analyze format is saved with a header file and a data file (you supply only the header file name and the voxel data is saved in a corresponding '.img' file) for example entering 'fred.hdr' creates two files:

fred.hdr
fred.img

The newest version of rview (>8.140) can save analyze format in 8-bit also: this is selected by simply including the term '8bit' at the end of the main part of the file name (before the extension) for example:

fred_8bit.hdr.
