"Webb21 mars 2024 · As you are actually only interested in the head, you likely can use simple thresholding, possibly try Otsu to define the head mask: mask = sitk.OtsuThreshold (image,0,1) and provide the mask as input to the bias field correction. Don’t forget to check that the mask actually segments the head. " - Simpleitk otsuthreshold
