Medial Axis Data

  This file is comprised of a header, medial axis coordinates, and medial axis burn numbers. The binary header is comprised of the following:

• nx (integer) horizontal dimension of data set
• ny (integer) vertical dimension of data set
• nvox (integer) number of voxels in medial axis

The medial axis coordinates follow next and are binary integers. The burn number is stored as a one dimensional sequence of binary unsigned characters. Each slice is stored in a separate file.
