Hi Ivan,
Have you tried connecting a RegionOfInterestImageFilter
after the ImageFileReader ?
Several months ago we implemented some streaming functionalities
in the readers to allow for reading only the regions of the image
that have been requested.
I'm not sure if this was tested on multi-frame DICOM images,
but it is probably worth giving it a shot.
Please let us know what you find,
Thanks
Luis
