Registration between skull and skull-stripped image

1

Hi.
I am working on anonimized mri images which as been skull stripped , but, in order to do source reconstruction, I’d need to reconstruct the skull. For this purpose I have some template images, which have not been betted. I am wondering if in Mrtrix3 it is possible to do the following steps:

  1. bet the template image in order to select just the skull and remove the brain inside
  2. register the skull-stripped image and this template skull
    thanks,
    Rosella

Both of these steps are best performed using other packages:

  1. bet is an FSL tool, there is no real equivalent in MRtrix3.
  2. For registration, I would recommend you use the ANTs tools, or FSL’s FLIRT tool.

thank you. DO you think ANT’s is also able to register one image inside another?
thanks

For the registration part, I would register your skull-stripped images to the original template (not just the skull) and apply the estimated transformation to the template skull. Should work… :crossed_fingers:

So , you mean to register a skull-stripped brain to a non-skull stripped template with ANTs, and then use this transformation to just register the skull-stripped brain to the skull?
thank you very much
