1      Definition

A Data Type including the arrangement of the Ultrasound Objects and the Ultrasound Sub-Scenes in a scene.

2      Functional Requirements

An Ultrasound Scene Geometry instance must include:

  1. The Ultrasound Scene Geometry Header
  2. The ID of the Ultrasound Scene Geometry.
  3. The ID and the Space-Time information of the Ultrasound Objects in the Ultrasound Scene.
  4. The ID and the Space-Time information of the Sub-Ultrasound Scenes in the Ultrasound Scene.

An Ultrasound Scene Geometry instance may include:

  1. The ID of a Virtual Space (M-Instance) to which it refers.
  2. The ID of a U-Environment to which it refers.
  3. The Space-Time information of this Ultrasound Scene Geometry instance.
  4. Information about this Ultrasound Scene Geometry.
  5. Descriptive Metadata.

5     Conformance Testing

A Data instance Conforms with Ultrasound Scene Geometry (OSD-USG) if:

  1. The Data validates against the Ultrasound Scene Geometry’s JSON Schema.
  2. All Data in the  Ultrasound Scene Geometry’s JSON Schema
    1. Have the specified type
    2. Validate against their JSON Schemas
    3. Conform with their Data Qualifiers.
