[vtkusers] How to remove tissue for MIP?

I have successfuly implemented a MIP (max intensity projection) in my
program. I did it like in VolView - a simple ramp for the preset. Now I want
to add some threshold sliders to remove tissue from the MIP. For example I
wanna remove tissue of high values (bones) so I can see soft tissue
in the MIP which is usually covered by the bones. So I'm looking for a good
1. I could manipulate the preset ramp but that would not lead to a desired
2. I could also manipulate manually the original volume data before the
calculation of the MIP and decrease all voxels specified by the theshold.
But that would take a lot of memory and would be very slowly.
So does anybody know another alternative? Maybe I could use a special VTK
filter or something?
