[FieldTrip] Extra Noise

[Isaiah C. Smith]

Hello All,

I have been trying to get rid of the noise when I create the mesh for this image in the neck area and the areas above the scalp. The MR Images have nothing below the nose area and there seems to be no contrast change in the image backgrounds to cause this result. [cid:9CC3E462-A99E-4540-9D53-E4519F967028 at socal.rr.com] [cid:F80D2CB7-391E-4688-95CF-A18E4425E8C4 at socal.rr.com]

I am really stumped as to how to change this, These different results were gotten by changing the threshold and the mesh number slightly. However, each time I redo the process from the original images the chances of “horn” being in front or on top of the head seem to shift. In some cases, there are both. If anyone could help. It would be greatly appreciated. Is there some automated way to get rid of these extra vertices?

Isaiah
