9.5.2 Behavior

A success response shall contain the Target Resource in an Acceptable Rendered Media Type. See Section 8.7.4.

The Target Resource shall be rendered and returned as specified in the Query Parameters. Presentation State transformations are applied using the appropriate rendering pipeline specified in Section N.2 “Pixel Transformation Sequence” in PS3.4. Any Source Image Region parameters are applied after any Presentation State parameters. Any Viewport parameters are applied after any Source Image Region.

Even if the output of the image is defined in P-Values (grayscale values intended for display on a device calibrated to the DICOM Grayscale Standard Display Function PS3.14), or contains an ICC profile, the grayscale or color space for the rendered image is not defined by this Standard.

However, if any of the following are true:

  • the Target Resource is not a multi-frame image or video,

  • the number of parameter values is not equal to one, or

  • the parameter value is not a positive integer less than or equal to the number of frames in the Instance

the origin server shall return a 400 (Bad Request) responseand may include a payload containing an appropriate error message.
