<p>Good afternoon</p>
<p> </p>
<p>New to GATE and want to simulate SPECT. Using vGATE.</p>
<p> </p>
<p>I ran through the SPECT in the user contribution file. The simulation run and I can open the root file.</p>
<p> </p>
<p>My question – if this is a SPECT scan, can the simulation results be constructed such that a cylinder is visualized, much like after a cylinder is scanned using a real gamma camera?</p>
<p> </p>
<p>Thank you,</p>
<p> </p>
