I have a matrix of a stack of images of a tumor, and I would like to come up with a way to create a rough 3D image of that tumor by taking one ROI in both the X and Y directions and three in the Z direction, for a total of five ROIs that together create a sort of blimp-like thing and interpolate the missing slices to form a simple 3D structure to allow us to have a look at the tumor. I've got the ROIs all worked out, now I'm just working on the actual 3D interpolation and display. Since I'm only using 5 ROIs I'm not expecting it to be totally accurate - really it's just for us to get an idea. I've experimented with the interp functions, as well as attempted to write my own, but thus far I've had no luck and I'm not sure I'm even approaching this from the right perspective. Any ideas are much appreciated. Thanks!
