I have a total of 48 hours experience with GATE, but learning fast! I have done other Monte Carlo imaging simulations, but not with GATE. I have NCAT digital phantom configurations of myocardial perfusion distributions for F-18, N-13 and Rb-82 tracer distributions, and corresponding anatomy (attenuation coefficient maps). I am wondering if anyone has previously generated ‘high-count/low-noise’ sinograms of these types of object distributions, for any of the radionuclides that they would be willing to share. Uniform uptake (normal) or disease configurations would both be acceptable. At this phase of my project, I am not particular about the type of scanner etc. - any of the standard models that are available in the current GATE distribution would be acceptable. <o:p></o:p><o:p> </o:p>All appropriate credit for contributions of the sinograms or any additional effort that resulted would certainly be recognized academically in publications etc. I just thought that this was worth asking about before the effort to install and learn GATE. <o:p></o:p><o:p> </o:p>I hope that this is a sufficient description. I could provide more details as needed.<o:p></o:p><o:p> </o:p>Many thanks in advance,<o:p></o:p><o:p> </o:p>Jim <o:p></o:p><o:p> </o:p>S.
