Dear Choi,<br>for voxelised phantom you must first convert your phantom to uint16 (eg: with matlab) and then convert it to interfile format (eg: with Xmedcon). then according to GATE voxel_phantom example change it's header file to correct format. secondly if you use voxelised source, displace the whole voxel_source to 1/2 of each dimension .<br>
at the end make sure that world dimension is larger than all shapes or phantoms that used.<br><br>hope this help you<br><br><br><div class="gmail_quote">2009/10/28 Yu-Na Choi <span dir="ltr"><<a href="mailto:choyyuna@yonsei.ac.kr">choyyuna@yonsei.ac.kr</a>></span><br>
