K Rendered Volume Response Module

The Rendered Volume Response Module provides the user agent with a representation of the parameters applied by the origin server to generate the volumetric rendering.

The user agent may use this information to:

inform the operator of the actual parameter values used, including both values specified in the request and values determined by the origin server (e.g., populate the user interface with parameters to aid in the interpretation of rendered content),
serve as the basis for subsequent requests (e.g., to iteratively modify parameters to obtain a desired rendering outcome), or
provide insight into the choices made by the origin server to select defaults and/or address errors when producing the rendering.

K.1 Response Message Body

Table K.1-1 defines the Attributes that are returned in a Rendered MPR Volume Resource or a Rendered 3D Volume Resource response message body.

Note

These represent Query Parameters that may be specified by the user agent in Rendered MPR Volume Resources or Rendered 3D Volume Resources. See Section 8.3.5.3.
Anatomic orientation parameters (see Section 8.3.5.3.4) are converted to camera orientation parameters to facilitate fine grain adjustments in a subsequent request.
