Listmode SPECT would suggest that you rotate your camera quite fast and continuously which is unusual practice.<br>

I think that no software can do that.<br>

Not much to do to allow listmode SPECT reconstruction in CASToR though. The computation of the sensitivity image has to be implemented. Then, the only limitation would be that you have to use preset angle positions for the camera, as opposed to continuous.<br>

<p>Dear Dev,</p>
<p>I am using SIMIND to generate list mode data for SPECT. Is there any support for reconstruction using list mode? Are you planning on releasing it soon? If not can you suggest any other software to do so. Thank You. </p>
