ULTRASOUND MULTIFRAME (US MF) INFORMATION OBJECT IMPLEMENTATION 5.1 INTRODUCTION This section specifies the use of the DICOM US Multi-frame Image IOD to represent the information included in US images produced by this implementation. Corresponding attributes are conveyed using the module construct. The contents of this section are: 5.2 - IOD Implementation 5.3 - IOD Entity-Relationship Model 5.4 - IOD Module Table 5.5 - IOD Module Definition 5.2 US MF IOD IMPLEMENTATION This section defines the implementation of US Multi-Frame image information object. 5.3 US MF ENTITY-RELATIONSHIP MODEL The Entity-Relationship diagram for the US MF Image interoperability schema is shown in Illustration 5.3-1. In this figure, the following diagrammatic convention is established to represent the information organization: · each entity is represented by a rectangular box · each relationship is represented by a diamond shaped box. · the fact that a relationship exists between two entities is depicted by lines connecting the corresponding entity boxes to the relationship boxes. The relationships are fully defined with the maximum number of possible entities in the relationship shown. In other words, the relationship between Series and Image can have up to n Images per Series, but the Patient to Study relationship has 1 Study for each Patient (a Patient can have more than one Study on the system, however each Study will contain all of the information pertaining to that Patient).

LOGIQ 7 GE HEALTHCARE DICOM CONFORMANCE STATEMENT DIRECTION 2316173-100REV 7.03 49 5.4 IOD MODULE TABLE Within an entity of the DICOM US Multi-Frame IOD, attributes are grouped into related set of attributes. A set of related attributes is termed a module. A module facilitates the understanding of the semantics concerning the attributes and how the attributes are related with each other. A module grouping does not infer any encoding of information into datasets. Table 5.4-1 identifies the defined modules within the entities, which comprise the DICOM US Multi- Frame IOD. Modules are identified by Module Name. See DICOM Part 3 for a complete definition of the entities, modules, and attributes.

The following modules are included to convey Enumerated Values, Defined Terms, and Optional Attributes supported. Type 1 & Type 2 Attributes are also included for completeness and to define what values they may take and where these values are obtained. It should be noted that they are the same ones as defined in the DICOM Standard Part 3 (Information Object Definitions).
