Hi Congying, I've been a little separated from the coding on SIRF over the last few months, but I don't believe the MHKEM has been incorporated into SIRF. The development required would not be particularly huge (I think?). Although it would probably require some C++ level changes in SIRF to support the vector of anatomical images. However, it is all up and running in the STIR engine itself. I'd suggest you have a go with STIR first. Depending how familiar you are with STIR, I'd suggest first making sure you are able and comfortable to do a regular OSEM reconstruction. Once you're happy there, it is very simple to try [M]HKEM, see the example parameter file Daniel wrote here: https://github.com/UCL/STIR/blob/master/examples/samples/KOSMAPOSL_mhkem.par If you're not so familiar with STIR, the User Guide is best to start. (Kris - the version on sourceforge is old, is there an updated version? I've attached my most recently compiled version, which is a few weeks old just before 4.0) You could use some of the publicly available information from the private Short Course run at MIC in 2018: http://stir.sourceforge.net/MIC2018ShortCourse/main.htm https://github.com/UCL/STIR-exercises Converting your own data from the scanner can be a bit tricky, here's a starting point: https://github.com/SyneRBI/SIRF/wiki/PET-raw-data Cheers, Ash -- Ashley Gillman Postdoctoral Research Fellow | CSIRO AEHRC E [log in to unmask]<mailto:[log in to unmask]> | T +617 4753 8531 | M +61 404 085 204 From: SyneRBI Users list <[log in to unmask]> On Behalf Of Cy Chu Sent: Monday, 11 May 2020 8:19 PM To: [log in to unmask] Subject: About the MHKEM Dear SIRF Team, Recently, I have noticed that the HKEM method available in SIRF seems to be updated to MHKEM which could work with multiple anatomical priors simultaneously (https://github.com/UCL/STIR/pull/424/). I am wondering whether this MHKEM approach has become available in STIR or SIRF? If the new approach is available now, is it possible to find an example of using it? I really want to try this kernel-based method with our mMR PET data. Thank you very much.
