Does anyone have a good solution to automatically figuring out the threshold to obtain a skull mask for head CT images? The histogram from imtool shows me that the best threshold range would probably be between two peaks which isn't too helpful.

You could pre-map your input image to have the intensity range expected by your code using imadjust,
J = imadjust(I,[low_in high_in],[low_out high_out])You forgot to attach re.dcm.
Get rid of the histogram equalization call - that never helps. It's totally unnecessary.
