Presentation Sequence (0070,x102) Set to the same UID value in each of the Collection UID presentation state instances indicating that the views are sequentially ordered. Presentation Sequence (0070,x103) Number indicating the ordering of the views in the Position Index stack. Y.3.3.3 Encoding Details: Crosscurve Animation method In this method, a single presentation state instance defines the initial slice. Crosscurve animation is defined using a straight-line curve whose length is the difference between the first and last slices in the stack and the step size indicates the spacing between slices. Y.3.3.3.2 Presentation Animation Module Recommendations Table Y.3.3-2 Presentation Animation Module Recommendations Attribute Name Tag Comment Presentation Animation Style (0070,xA01) Set to “CROSSCURVE” Recommended Animation (0070,xA03) This can be used by the viewing application to Rate automatically move the Planar MPR view along the curve through the volume. Animation Curve Sequence (0070,xA04) Specifies the curve as a number of 3D contour points Animation Step Size (0070,xA05) How far to move the Planar MPR view along the curve in one step. Y.3.4 Annotations in Volume Space (example: Trajectory Planning) Y.3.4.1 User Scenario The Planar MPR VPS SOP Class makes it easy for the receiving viewing application to enable the user to modify the initial view for viewing nearby anatomy. However, this requires that display relative annotations which have been defined in the Presentation State with 2D coordinates in the Graphic Annotation module need to be removed when the initial view gets manipulated. Otherwise there would be the risk that the annotations point to the wrong anatomy. To give the viewing application more control over when to show annotations, the Planar MPR VPS SOP Class allows to define annotations in volume space. As an example, during intervention trajectory planning one or more straight lines representing the trajectories of a device (e.g. needle) to be introduced during further treatment (e.g. cementoplasty, tumor are drawn by the user on a planar MPR view. ablation…) …
