(dura_img=None, pvcsf_img=None, arteries_img=None, save_data=False, overwrite=False, output_dir=None, file_name=None)[source]¶ Filter stacking
A small utility to combine multiple priors derived from filtering of the CSF partial voluming, arteries, and/or remaining dura mater. The filter priors (in [0,1]) are arranged in a specific way (in increments of 2) that is expected by the Filters contrast type in MGDM
Parameters: - dura_img (niimg, optional) – Prior for the location of remaining dura mater after skull stripping. At least one prior image is required
- pvcsf_img (niimg, optional) – Prior for the location of CSF partial voluming (mostly in sulcal regions). At least one prior image is required
- arteries_img (niimg, optional) – Prior for the location of arteries, visible e.g. in MP2RAGE images. At least one prior image is required
- save_data (bool) – Save output data to file (default is False)
- overwrite (bool) – Overwrite existing results (default is False)
- output_dir (str, optional) – Path to desired output directory, will be created if it doesn’t exist
- file_name (str, optional) – Desired base name for output files with file extension (suffixes will be added)
Returns: Dictionary collecting outputs under the following keys (suffix in brackets)
- result (niimg): Combined image, where only the strongest priors are kept (_bfs-img)
Return type: Notes
