A.71 Legacy Converted Enhanced MR Image IOD

A.71.1 Legacy Converted Enhanced MR Image IOD Description

The Legacy Converted Enhanced Magnetic Resonance (MR) Image Information Object Definition (IOD) specifies an image that has been converted from images originally created by a magnetic resonance imaging device.

A.71.2 Legacy Converted Enhanced MR Image IOD Entity-Relationship Model

The E-R Model in Section A.1.2 depicts those components of the DICOM Information Model that directly reference the Legacy Converted Enhanced MR Image IOD.

A.71.3.1 Legacy Converted Enhanced MR Image IOD Content Constraints

The General Image Module, Overlay Plane Module, VOI LUT Module, Supplemental Palette Color Lookup Table Module and Graphic Annotation Module shall not be used in a Standard Extended SOP Class of the Legacy Converted Enhanced MR Image.

Note

In order to annotate images, whether during acquisition or subsequently, SOP Instances of the Grayscale Softcopy Presentation State Storage or the Structured Report Storage SOP Classes that reference the image SOP Instance, may be used.

No standard mechanism is provided for inclusion of annotations within the image SOP Instance itself, and implementers are discouraged from using private extensions to circumvent this restriction.

Grayscale Softcopy Presentation State Storage Instances that are generated during conversion shall be referenced from the Image SOP Instance by using the Referenced Grayscale Presentation State Sequence in the Enhanced MR Image Module. See Section C.8.15.2.

Note

The Curve Module has been retired from DICOM. It is still not permitted to be present. See PS3.3-2004.
