Foreword

This draft Supplement to the DICOM Standard was developed according to NEMA Procedures. This 

Supplement to the Standard is developed in liaison with other standardization organizations including CEN 

TC251 in Europe, MEDIS-DC and JIRA in Japan, with review also by other organizations including IEEE, 

HL7 and ANSI in the USA. 

The DICOM Standard is structured as a multi-part document using the guidelines established in the 

following document: 

- ISO/IEC Directives, 1989 Part 3 : Drafting and Presentation of International Standards. 

This document is a Supplement to the DICOM Standard. It is an extension to PS 3.3, 3.6 and 3.11 of the 

published DICOM Standard which consists of the following parts: 

PS 3.1 - Introduction and Overview 

PS 3.2 - Conformance 

PS 3.3 - Information Object Definitions 

PS 3.4 - Service Class Specifications 

PS 3.5 - Data Structures and Encoding 

PS 3.6 - Data Dictionary 

PS 3.7 - Message Exchange 

PS 3.8 - Network Communication Support for Message Exchange 

PS 3.9 - Point-to-Point Communication Support for Message Exchange 

PS 3.10 Media Storage and File Format for Data Interchange 

PS 3.11 Media Storage Application Profiles 

PS 3.12 Media Formats and Physical Media for Data Interchange 

PS 3.13 Print Management Point-to-Point Communication Support 

PS 3.14 Gray-scale Display Function Standard 

These parts are related but independent documents.

Scope and Field of Application 

This Supplement to the DICOM Standard specifies changes to the DICOM Image Information Object 

Definition (IOD) for Ultrasound (US) and Ultrasound Multi-frame (USMF) Images. It specifies the new 

modules necessary to identify images acquired as part of an ultrasound acquisition protocol. 

Since this document proposes changes to existing Parts of DICOM the reader should have a working 

understanding of the Standard. 

This proposed Supplement includes a number of Addenda to existing Parts of DICOM: 

1. PS 3.3 Addenda (Extension to Annex A and Annex C) 

2. PS 3.6 Addenda (Extension to Section 6) 

3. PS 3.11 Addenda (Extension to Annex C)

Part 3: Information Object Definitions

3.X Ultrasound 

The following definitions are commonly used in the specification of the Ultrasound IOD’s. 

3.X.1 Acquisition Protocol 

An Acquisition Protocol is a Procedure Type that defines the particular ultrasound images that will be 

acquired. 

Note: These can be well known or locale specific. 

3.X.2 Staged Protocol 

A Staged Protocol is an Acquisition Protocol that is repeated at more than one specific instance of time. 

Note: These instances commonly occur due to simple events. The introduction of contrast media, drugs or stress 

to the patient are typical events. 

Item: Add to PS 3.3 Table A.1-1 

A.1.4 Overview of the Composite IOD Module Content 

Table A.1-1 provides an overview of the Modules used throughout the Composite IODs. This table is for 

informative purposes only. It is based on the IOD definitions found in the remaining sections of Annex A 

which are normative.

A.6.4.1 Mutually Exclusive IEs 

The Image and Curve IEs are mutually exclusive. Each SOP Instance using this IOD shall contain exactly 

one of these IEs. 

A.6.5 US Image IOD Relationship to the DICOM Real-World Model 

Ultrasound images that make use of the US Series & Protocol Modules have a more specific 

relationship to the DICOM Real-World Model than non-protocol images. An ultrasound acquisition 

protocol is considered one Requested Procedure and has one Procedure Plan. The Procedure 

Plan will have one or more Action Items. An ultrasound acquisition protocol will typically consist

of one Scheduled Procedure Step containing one or more Action Items. Assuming the acquisition 

protocol was successfully completed, this will result in one Modality Performed Procedure Step. 

Therefore, all images that are part of this particular instance of an ultrasound acquisition protocol 

will have the same Procedure Code Sequence (0032,1064). It is recommended that all the images 

that are part of this particular instance of an ultrasound acquisition protocol have the same 

Performed Procedure Step ID. In an environment with information system connectivity, the 

Procedure Code Sequence can be used to identify all the images that were acquired as part of that 

protocol. If no information system connectivity is available, then Performed Procedure Step ID 

may be used to identify all the images that were acquired as part of that protocol. 

It is recommended that each stage should map to a separate series.

A.7.5 US Multi-Frame Image IOD Relationship to the DICOM Real-World Model 

Ultrasound images that make use of the US Series & Protocol Modules have a more specific 

relationship to the DICOM Real-World Model than non-protocol images. An ultrasound acquisition 

protocol is considered one Requested Procedure and has one Procedure Plan. The Procedure 

Plan will have one or more Action Items. An ultrasound acquisition protocol will typically consist 

of one Scheduled Procedure Step containing one or more Action Items. Assuming the acquisition 

protocol was successfully completed, this will result in one Modality Performed Procedure Step. 

Therefore, all images that are part of this particular instance of an ultrasound acquisition protocol 

will have the same Procedure Code Sequence (0032,1064). It is recommended that all the images 

that are part of this particular instance of an ultrasound acquisition protocol have the same 

Performed Procedure Step ID. In an environment with information system connectivity, the 

Procedure Code Sequence can be used to identify all the images that were acquired as part of that 

protocol. If no information system connectivity is available, then Performed Procedure Step ID 

may be used to identify all the images that were acquired as part of that protocol. 

It is recommended that each stage should map to a separate series.
