// Code developed by:

// S. Agostinelli, F. Foppiano, S. Garelli and M. Tropeano

// Brachytherapy simulates the dose deposition in a cubic (30*cm)

// water phantom for a Ir-192 MicroSelectron High Dose Rate
|
|
// brachytherapy source.
|
|
//
|
|
// Simplified gamma generation is used.
|
|
// Source axis is oriented along Z axis.
|
|
// Voxel data on the X-Z plane is output to ASCII file
|
|
// "Brachy.out".
