Class RealWorldValueTransform


  • public class RealWorldValueTransform
    extends java.lang.Object

    A transformation constructed from a DICOM attribute list that extracts those attributes which describe how stored pixel values are translated into real world values (e.g., Hounsfield Units, cm/s).

    Looks first for a per-frame functional group RealWorldValueMappingSequence then looks in the shared functional groups, then the top level of the dataset, as well as trying to find the Rescale Slope and Intercept values in the top level of the dataset.

    Note that multiple transformations (for each frame) may be present and are supported.

    Does not currently support a LUT in the Modality LUT Sequence, only linear rescale values.
