Great talk and discussion today on prospective motion detection/correction methods:
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)
