Dear gate users,<br>I beg your pardon, i sent similar email several weeks ago but i did not receive any response for this problem. in summary i questioned tow things:<br><br><span style="color: rgb(51, 51, 255);">1-I used GATE for dosimetry application. When i start the simulation in
GATE4 it successfully completed with no error but there was seen
absorbed dose in Vacuum out of phantom (my phantom is a sphere with the
point source in it's center).</span><br style="color: rgb(51, 51, 255);"><br style="color: rgb(51, 51, 255);"><span style="color: rgb(51, 51, 255);">2- when i calculate the total energy deposition in phantom (from the absorbed dose*m) the total deposited energy in phantom is higher than energy emitted from the point source in phantom center.</span><br>
note:<br>-i use voxelised phantom and source.<br>- i translate the point source to real center of phantom (according to gate user's guide).<br><br>help me to find out the reason of those cases in GATE.<br clear="all">
