<div><div id="yiv1855322533"><div dir="ltr">Dear all,<div><br></div><div>I would like to simulate a multi-energy SPECT scanner using a source with built-in energy distribution, arbitrary point-wise spectrum (Arb), using the following command: </div><div><br></div><div>/gate/source/[NAME]/gps/energytype Arb <br></div><div><br></div><div>
Although there is another way to define using "UserSpectrum", there is no instruction on how to define the energy points and the corresponding weights using the "Arb". Any help would be highly appreciated. </div><div><br></div><div>Hojjat </div></div>
