<br></div><div style="color:rgb(0,0,0);font-family:Tahoma;font-size:13px">I am trying to create a realistic PET image using a phantom image (w/ various activities in different parts of anatomy). <span style="font-size:10pt">So the phantom can in principle emit photon-pair at each voxel location......so if each voxel can emit photon(s), the phantom would behave like a voxelized source, then? </span></div>

<div>1. Can GATE read binary? Do I need to convert the image into another format?</div><div><br></div><div>2. How do I use insert the phantom in the written macro of a PET scanner? </div><div><br></div><div>Thanks!</div>
