[vtkusers] Memory problem

[Raúl Ferriz]

Hi all!

I have some memory problems with VTK. I'm trying to load very big DICOM 
series through gdcm and show Axial, Sagittal and Coronal images. Also I 
render a 3d visualization of the dicom. All work good until I try to 
load a very big DICOM, I have 2 Gb of ram, and another machine with 1,5 
Gb of ram. I have one dicom that load perfectly on first machine, but 
fails with an "Unable to allocate xxxx of 8 bytes" (sorry I don't 
remember the number, but this is not really very important). On the 
other machine this dicom works good, but when I unload and reload some 
other dicoms, evetually it fails with same error. I had concluded that 
on first machine fails after some memory fragmentation, because I'm sure 
that all not needed memory is freed. But on second machine (1.5Gb) there 
is not enough memory to allocate that Dicom fully on memory.

Is there a way to avoid this problem? Can streaming be the solution?
