 * @class   vtkGESignaReader
 * @brief   read GE Signa ximg files
 *
 * vtkGESignaReader is a source object that reads some GE Signa ximg files It
 * does support reading in pixel spacing, slice spacing and it computes an
 * origin for the image in millimeters. It always produces greyscale unsigned
 * short data and it supports reading in rectangular, packed, compressed, and
 * packed&compressed. It does not read in slice orientation, or position
 * right now. To use it you just need to specify a filename or a file prefix
 * and pattern.
 *
 * This reader doesn't support reading from memory.
