DCMTK

Description

Status: A large part of ''DcmItem::checkAndUpdateVR()'' implemented
See http://forum.dcmtk.org/viewtopic.php?p=4984

The rule in DICOM part 5 section 8.3 is that WaveformData, when read in implicit VR
shall be converted to OB iff WaveformBitsAllocated==8 and OW otherwise.
We currently always convert to OB, which is wrong.

==== Comments (MO?) ====

This is about writing data in Explicit VR, which will be either arranged in RAM or read into Implicit VR.

This could also concern LUT Data (general checks, to what extent other tags that can have other VRs are affected)

List of "polymorphous attributes" from DICOM 2009 that can take on various data types:
