The CARMA DBP: MRI-based study and treatment of atrial fibrillation

Pilot Studies on a Registration & Segmentation Pipeline & Workflow

  • Overall processing steps are (order tentative)
    • coarse registration MRA>cMRI
    • ROI definition (manual box ROI or automated via atlas)
    • N4 bias field correction for the MRI (surface coils): requires definition of ROI, unlikely to be successful on entire image
    • refined registration intra subject MRA->cMRI
    • segmentation of LA from MRA -> inner wall
    • segmentation of LA wall
    • segmentation of enhancement within LA wall: intensity statistics
    • registration follow-up -> baseline
