GG.6 Application Behavior for Standard SOP Classes

This section specifies SOP Class specific behaviors for conformant applications.

GG.6.1 Hanging Protocol SOP Class

GG.6.1.1 Instance Creator

An implementation that conforms to the Hanging Protocol Storage SOP Class as an SCU and is a SOP Instance creator shall state in its Conformance Statement:

  • The manner in which the values of the Hanging Protocol IOD Attributes are derived from displayed images, layouts, operator intervention or defaults.

  • Any Private Attributes that are used as the value of Selector Attribute (0072,0026) in the Image Set Selector Sequence, Filter Operations Sequence or Sorting Operations Sequence.

  • The optional Attributes that may be included in a Hanging Protocol SOP Instance.

GG.6.1.2 Display Application

An implementation that conforms to the Hanging Protocol Storage SOP Class as an SCP and interprets the contents of instances of the SOP Class to control the display of images, shall apply all mandatory Hanging Protocol and presentation intent Attributes to the sets of displayed images. Such an implementation shall state in its Conformance Statement:

  • The range of display environments that the application will support (e.g., number of screens, size of screens, overlapping image boxes).

  • The optional Attributes of the Hanging Protocol IOD that it is capable of interpreting and those that are not supported.

  • Description of application behavior when the value of Partial Data Display Handling (0072,0208) is ADAPT_LAYOUT or zero length.

  • Description of application behavior when the display environment of the Hanging Protocol Instance differs from the display environment of the application, with respect to preserving layout versus spatial resolution.

  • The Image Storage SOP Classes for which the Hanging Protocol Storage SOP Class is supported for display control.
