Hi Beth,

I had no try the 16 bit TIFF support of Mathematica. 
But I assume it is not implemented. I can offer you
only my PNG bitmap package that *has* the feature to
import and export 16 bit PNG images. So if your original
program can write 16 bit PNG you  should donnload the
MathPNG package from

http://www.mpae.gwdg.de/~kuska/mcpng.html

and transform the PNGBitmap[] object to a normal matrix.

Hope that helps
  Jens
