<p class="MsoNormal">I am simulating a proton pencil beam and I am trying to score the depth-dose curve in a cylindrical geometry. When I attach the dose actor to the cylindrical geometry, it appears that the dose is being calculated in a box as opposed to
a cylinder. I ran the same simulation but scoring dose in a cuboid geometry whose X and Y lengths were the same as the diameter (for the same depth resolution) of the cylindrical volume and I get the exact same curve. How would I define the dose actor in order
to score dose in the cylinder?<o:p></o:p></p>
