B.33 Render a Study as an MPR

This example illustrates a request to render a study as an MPR, returned as a 30fps MPEG4 video animating an Oblique orientation (specified using viewpoint parameters). The request also specifies a window width of 400 and center of 40 and a rendering method of average intensity projection. The user agent specifies that the rendered instances should consist of the multi-phase cardiac acquisition frames for the R-R interval between 140 and 260 milliseconds.

Note

See Section C.2.2.2 in PS3.4 for Attribute Matching.

The origin server will need to identify the relevant instances in the study (based on the presence of Cardiac R-R Interval Specified (0018,9070) with matching values). Since an animation step size was not specified, and a temporal range is specified (for the Cardiac R-R interval), the origin server understands that a temporal animation of multiple series each containing a single phase is requested. Since MPR slab thickness is not specified, the server renders a thin MPR, meaning a minimally thick slab of unspecified thickness.
