I’m looking for tools/libraries which enable the simulation of artifacts in MRI acquisitions. Anyone familiar with something of the sort? Maybe @effigies@oesteban@satra@neurolabusc ?
Any relevant resources would be greatly appreciated.
indeed possum can help. there is some work that both francisco’s group at nimh and doug’s group at mgh were doing in the last few years on this topic. i don’t think either are on neurostars. also, i saw a nice presentation of a simulator from a group in netherlands during ismrm last year. you may want to check the abstracts.
Thank you! These are great leads.
I have to admit that I find POSSUM’s legacy installation status somewhat worrying, but it certainly seems like a strong choice.
Also, @raamana, thanks for also mentioning BrainWeb. I wasn’t familiar, and it is a very interesting project.
you’re welcome. i had been wanting to spend more time in that direction but was unable to, so I am happy to be learning more about and contributing to what you and others in this space would achieve.
A deeper understanding of k-space can often help one understand artifacts. Many simulators exist, and ‘extreme’ values of various parameters sometimes give insights: https://kspace-explorer.streamlit.app/
