This node calculates the Euclidean distance transform of a binary mask. Each voxel value in the resulting image represents the euclidian distance to the closest edge voxel in the mask, i.e. the length of the line segment which connects that voxel to the nearest point on the perimeter of the mask. By default, the distance map is unsigned, but the filter can output signed distance maps by changing settings.
Type: Mask, List, Required, Single
Output image(s), containing the Euclidian distance transform of each mask.

Values: mm, Voxels
Signed Distance Map Boolean
Output a signed distance map, where inside and outside distances are of opposite sign.
Inside is Selection
Define if the inside of a mask should be positive of negative in a signed distance map.
Values: Negative, Positive
