A.5 Nuclear medicine image information object definition

A.5.1 NM Image IOD Description

The Nuclear Medicine (NM) Image Information Object Definition (IOD) specifies an image that has been created by a nuclear medicine imaging device. This includes data created by external detection devices that create images of the distribution of administered radioactive materials in the body. Depending on the specific radio pharmaceutical administered and the particular imaging procedure performed, problems involving changes in metabolism, function, or physiology can be investigated and various regional pathologies can be studied.

A.5.2 NM 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 NM Image IOD. The Modality LUT IE is not a component of the NM Image IOD.

A.5.3 NM Image IOD Module Table (Retired)

Section A.5.3 was defined in a previous version of the DICOM Standard. The Section is now retired.
