1 Definition
A Data Type including a collection of Basic Ultrasound Objects.
A Ultrasound Object can have a hierarchical structure where Ultrasound Objects contain Basic Ultrasound Objects and Ultrasound Objects.
2 Functional Requirements
A Ultrasound Object may include:
- ID of a Virtual Space (M-Instance) where it is or intended to be located.
- ID of the Ultrasound Object.
- Space-Time information of the Ultrasound Object.
- Basic Ultrasound Object and Ultrasound Objects included in the Ultrasound Objects.
Note that.
- A Ultrasound Object that does not include Sub-Scenes and only one Basic Ultrasound Object is a Basic Ultrasound Object.
- The Space-Time information of a Basic Ultrasound Object and Ultrasound Object included in a Ultrasound Object may be superseded by the Space-Time information of the Ultrasound Object containing them.

5 Conformance Testing
A Data instance conforms with Ultrasound Object (OSD-USO) if:
- The Data validates against the Ultrasound Object JSON Schema.
- All Data in the Ultrasound Object JSON Schema:
- Have the specified type.
- Validate against their JSON Schemas.
- Conform with their Data Qualifiers.
