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
Example contrast MRI with thresholded MRA as color overlay
