Great talk and discussion today on prospective motion detection/correction methods: https://youtu.be/9_BH3NJcRzs

Some interesting technical/methodological questions/debate:

Should motion be measured in every neuroimaging acquisition, as a best practice/QC protocol?

That would provide us a way to have an objective known estimate of motion that happened, as opposed to relying on unreliable human memory

We also touched upon on the recurring debate on how do we define or rely on SNR in the motion detection applications?
And that there might potentially be a role for dynamic phantoms to validate the motion correction or motion detection methods, as it can provide a known ground truth in terms of the amount of motion that happened (as opposed to making a [likely inaccurate] assumption of simple rigid motion for human head)
