Hi all,

I want to register these two images. But the metal artifact is a bit heavy in the right one. (It’s because that patients had lead wire attached to their skin in order to mark the range of the breast.) Could I use any slicer module to reduce the artifact? Or are there any methods?

Hope for some suggestions. Thank a lot!

Crayon

Most registration algorithms can take optional image mask(s) as input to specify which regions of the image they can take into account for the registration. You can create a mask using Segment editor module where the additional wires are excluded. You may need to export your segment to a labelmap volume (right-click in Data module) to be able to use it as a mask in a registration module.
