<p>Hi Alessio,</p>
<p><br>
</p>
<p>thanks a lot!</p>
<p><br>
</p>
<p>We tried to create geometries with a CAD program to import more complex geometries and tested it with scoring in a box that is built inside Gate and with the same geometry built in the CAD program.
<br>
</p>
<p>When scoring edep we obtain a value of about 3000 MeV in the geometry built with Gate, when scoring in the CAD geometry we obtain a value of about 370 MeV. We imported the CAD geometries via a .stl file
<span>and the insert specification "tessellated</span>". We obtained the same behavior when scoring Edep in cylinders built in gate and with the help of a CAD programm.
<br>

<p>Kind regards</p>
<p>Leonie</p>

<span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US" lang="EN-US">thanks for your email. Concerning the first point you spotted could you be more precise? (for example what do you mean with “different results
with different order of magnitude”?). With respect to the second point, this is a known behavior of the dose actor. At the moment, it cannot handle correctly non-regular geometries as far as I know. I would recommend you to work with the edep and then post-process
the dose. <o:p></o:p></span></p>

<p><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black">we try to perform simulations of different detectors with Gate and have some problems when scoring dose and edep in different volumes, perhaps anyone can help us with these issues:<o:p></o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black">- When we score dose and edep in a gate constructed geometry and in the same CAD geometry we obtain different results with different orders of magnitude (even in rectangular geometries).<o:p></o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black"><o:p> </o:p></span></p>
<p><span style="font-family:"Calibri",sans-serif;color:black">- When we score dose and edep in non rectangular geometries we cannot recalculate the dose out of edep and it seems that the dose in Gate is calculated by a geometry surrounding the real geometry
but having rectangular corners, e.g. for a sphere of radius 0.5 cm the dose can be recalculated out of edep by a cube with side length 1 cm.
