also please explain why the file limit is 4GB and not more. is there any way to bypass this?
The Pixel Data (7fe0,0010) Data Element has a Length Field of 32-bit, so the maximum size of uncompressed pixel data is (usually) limited to about 4.2 GB.
Only recently, CP-2083 introduced a new Transfer Syntax that encapsulates the uncompressed pixel data (similar to compressed pixel data) and, therefore, allows for encoding more than 4.2 GB of pixel in uncompressed format.
Please note, however, that the DCMTK does not yet support this new Transfer Syntax (see DCMTK issue #1000).
