Maximum Intensity without FOR Loop [message #39404]

Hi there
a lot of posts talk about the necessity to avoid FOR loops ('if you
use for loops, make sure a lot of stuff is happening in there...').
However, I can't seem to find a better & working solution for the
following code fragment:

FOR i=0,x_resolution-1 DO BEGIN
FOR j=0,y_resolution-1 DO BEGIN
reformat_data[i,j,k]=MAX(data[i,j,lower_limit:upper_limit])
ENDFOR
ENDFOR

Background: data is a image stack (MRI 3D Data), we would like to find
the MIP (Maximum Intesity Projection) over a certain number of images.
The currrent solution is too slow, and a better solution highly
appreciated!
Algorithm-Freaks? Anyone?

Thanks for your help,
Stefan
