Dear Gate users,<br>hi,<br>I have some questions about GATE :<br><br>1-When i run voxelised phantom for dosimetry application the gate runs well, but at first it gives warning as below:<br><span style="color: rgb(51, 102, 255);">Time set to (s) 1.000e+00</span><br style="color: rgb(51, 102, 255);">

what means this warning? and how can debug it?<br><br>2- I simulate a voxelised source and phantom for dosimetry application, when i read the output file(dose file) there were seen dose in vacuum outside the phantom.(see attachment for 1MBq photons).<br>
in high activity level this problem is considerable.<br>note that:I followed GATE4.0.0 users manual for activity range and phantom range description. all of the macros associate with imaging (only) such as camera, digitizer, ... were deactivated.<br>
can anyone help me to solve this problem?<br><br>3- in gate results, energy emitted from one organ is less than energy absorbed in other organ, what is my problem.<br>for example:<br>in voxel phantom with 128*128*243 dimension with 4*4*4 mm^3 each voxel,<br>
Activity in kidney=500 M.Bq for 100 Kev photons for 1second<br>all of the energy emitted from kidney is about 0.16 e-5 Joule but energy absorbed in the same kidney is 0.10433 Joule.<br>is my problem about simulation parameters or energy calculation methods?<br>
