FF.2.3.2 Description of Display Components

FF.2.3.2.1 Classification Component Components

There are two classification component types currently defined for conversion from scalar input data to RGBA. The defined components are:

  • One Input -> RGBA: This component accepts reconstructed data from one input in the Volumetric Presentation State Input Sequence (0070,1201) and generates an RGB and an Alpha output. This classification component would be specified in an item of the Presentation State Classification Component Sequence (0070,1801):

    One Input -> RGBA Component

    Figure FF.2-3. One Input -> RGBA Component


  • Two Inputs -> RGBA: This component accepts reconstructed data from two inputs in the Volumetric Presentation State Input Sequence (0070,1201) and generates an RGB and an Alpha output. This component is used in the case where a two-dimensional color mapping needs to be performed. This classification component would be specified in an item of the Presentation State Classification Component Sequence (0070,1801):

    Two Inputs ->RGBA Component

    Note

    An example for the use of this component is to combine Ultrasound Flow Velocity and Ultrasound Flow Variance to produce a color range from red-blue based on flow velocity and adding a yellow-green tinge based on flow variance)
