Supplement 231: Variable Modality LUT Softcopy Presentation State

This supplement defines a new Presentation State service-object pair (SOP) Class for both grayscale and pseudo-colour. This new SOP class differs from existing SOP classes in that it allows the Modality LUT to be controlled for each image or frame. This is intended for modalities in which the dynamic range varies between images or frames, resulting in each referenced image having a different Modality LUT.
