## A.6 Ultrasound Image IOD

### A.6.1 US Image IOD Description

The Ultrasound (US) Image Information Object Definition specifies an image that has been created by an ultrasound imaging device.

### A.6.2 US 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 US Image IOD. The Overlay IE, Modality LUT IE and VOI LUT IE are not components of the US Image IOD.

### A.6.3 US Image IOD Module Table (Retired)

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

### A.6.4 US Image IOD Module Table

### Note

1. For the purpose of conveying ultrasound protocol data management information it is recommended that the Performed Protocol Code Sequence (0040,0260) be assigned the code value(s) of the performed ultrasound protocol, if any. The Baseline Context Group for these code values is CID 12001 “Ultrasound Protocol Types”.

2. The US Frame of Reference Module was previously included in this IOD, but has been retired. See PS3.3-2003.

#### A.6.4.1 Mutually Exclusive IEs

### Note

A Curve IE was previously included in this IOD that was mutually exclusive with the Image IE, but has been retired. See PS3.3-2004.
