Detailed Description

mitkAnalyzeImageReader -

mitkAnalyzeImageReader

Analyze image file sets consist of at least 2 files:

• an image file ([basename].img or [basename].img.gz or [basename].img.Z) This contains the binary represenation of the raw voxel values. If the file is uncompressed, it should be of of size (sizeof(storagetype)*NX*NY*NZ(*NT). The format of the image file is very simple; containing usually uncompressed voxel data for the images in one of the several possible voxel formats:
  • 1 bit packed binary (slices begin on byte boundaries)
  • 8 bit (unsigned char) gray scale unless .lkup file present
  • 16 bit signed short
  • 32 bit signed integers or float
  • 24 bit RGB, 8 bits per channel
• a header file ([basename].hdr) This a 348 byte file 99.99% of all images that contains a binary represenation of the C-struct defined in this file. The analyze 7.5 header structure may, however, be extended beyond this minimal defintion to encompase site specific information, and would have more than 348 bytes. Given that the ability to extend the header has rarely been used, this implementation of the Analyze 7.5 file will only read the first 348 bytes into the structure defined in this file, and all informaiton beyond the 348 bytes will be ignored.
