hi gaters,<div>I designed two multi-pinhole patterns, and I want to simulate two patterns at one simulation.</div><div>So I estimate two SPECT (SPECThead and SPECThead2)facing each other, but my output projection always get only one projection from SPECThead. SPECThead2 doesn't output anything. Can GATE simulate different system at same time?</div>
