<div class="">Dear Mr. Pietrzyk,<div class=""><br class=""></div><div class="">I would like to ask something about GATE. I am working on my Research task/master thesis and I am using GATE for simulation of radioterapeutic plans. I would like to know, how is number of monitor units (MU) converted to number particles according to stopping power in air. So if you can explain how does the GATE calculate this number. In Gate Users Guide I only found this: "<span style="font-family:Times;font-size:13pt;background-color:transparent" class="">In the "plan description file", each single spot is characterized by its position at treatment isocenter and also by its weight (intensity). By default, the weight
corresponds to the number of Monitor Units (MU) delivered and is converted into a number of particles according to the proton stopping power in air."</span></div><div class=""><br class=""></div><div class="">Thanks in advance,</div><div class="">Kateřina Poráková</div></div></div></blockquote></div><br class=""></body></html>
