A.46 Real World Value Mapping IOD

A.46.1 Real World Value Mapping IOD Description

The Real World Value Mapping Information Object Definition specifies a mapping of the stored pixel values of referenced images into some Real World value in defined units. This allows the capture of retrospectively determined mappings, e.g., for values that cannot be determined at the time of image acquisition and encoding.

Note

A particular use case is mapping of PET pixel values to counts, concentration, or standardized uptake values (SUVs) normalized by one of several factors.
