I am using GATE/Geant4 for simulating photon beams interacting with matter. For 3D dose distributions, GATE outputs the data into an Analyze 7.5 format . I was wondering whether there exists a function in Mathematica that could read files in this format and display the data. For what is worth, Matlab has
analyze75read  for this purpose.
( This comment will soon be deleted: I don't have access at the moment to my Mathematica installation, but here is a file in case anyone would like to play with it: http://leaf.dragonflybsd.org/~beket/geant4/Config-gamma-Dose.hdr and http://leaf.dragonflybsd.org/~beket/geant4/Config-gamma-Dose.img ).
