Dear Gate users,<br>
<br>
I have a question about dose calculation method in GATE.<br>
I would like to know how can GATE calculate and saves the dose in any
voxel of voxelised phantom? which files are associated for dose
calculation and save in GATE?<br>
on the other hand, if GATE saves energy deposited in any photon
interaction (Photoelectric or Compton) thus why all of the energy
deposited in a simple voxel phantom is larger than emitted energy?<br>(example:
for 20 MBq of 140keV point source in the sphere with radius of 24.6 cm
filled with water for 1 second simulation, absorbed dose is 1.0283 cGy
(equals to 0.64 Joule)but the emitted energy was about 1e-6 joule)<br clear="all">
can any one knows what is it's reason? <br><br>I think there is a bug in dose calculation of GATE in the voxel phantom...................? is it true idea?<br>is there any one uses GATE for Dosimetry applications?<br>
would any one please send me a complete macro for dose calculation?<br><br>my macro for dose calculation is in the attachment.<br clear="all"><br>-- <br>Ali Asghar Parach,Ph.D. student in Medical Physics,Tarbiat Modares University,Tehran,Iran<br>
