CP-1740 WSI is missing Frame Type Status Final Text Date of Last Update 2018/03/27 Person Assigned David Clunie Submitter Name David Clunie Submission Date 2017/07/09 Correction Number CP-1740 Log Summary: WSI is missing Frame Type Name of Standard PS3.3, PS3.6 2018a Rationale for Correction: WSI has no functional group to specify FrameType and hence there is uncertainty over conditions that depend on it, e.g., Frame Content data time and duration attributes that are conditioned on originality. Add a modality-specific Frame Type functional group macro to be consistent with all the other enhanced multi-frame family IODs.

Whole Slide Microscopy Image Frame Type Macro Attributes
Attribute Name Tag Type Attribute Description
Whole Slide Microscopy Image Frame Type Sequence (0040,0710) 1 Identifies the characteristics of this Whole Slide Microscopy Image frame. Only a single Item shall be included in this Sequence.
>Frame Type (0008,9007) 1 Type of Frame. A multi-valued attribute analogous to Image Type (0008,0008). Enumerated Values and Defined Terms are the same as those for the four values of Image Type (0008,0008). See .
For reference, unchanged:
Frame Content Macro specifies the attributes of the Frame Content Functional Group Macro. This Functional Group Macro may only be part of the Per-frame Functional Groups Sequence (5200,9230) attribute.
Frame Content Macro Attributes
Attribute Name Tag Type Attribute Description
Frame Content Sequence (0020,9111) 1 Identifies general characteristics of this frame. Only a single Item shall be included in this Sequence.
>Frame Acquisition Number (0020,9156) 3 A number identifying the single continuous gathering of data over a period of time that resulted in this frame.
>Frame Reference DateTime (0018,9151) 1C The point in time that is most representative of when data was acquired for this frame. See Section C.7.6.16.2.2.1 and Section C.7.6.16.2.2.2 for further explanation. The synchronization of this time with an external clock is specified in the synchronization Module in Acquisition Time synchronized (0018,1800). Required if Frame Type (0008,9007) Value 1 of this frame is ORIGINAL and the SOP Class UID is not "1.2.840.10008.5.1.4.1.1.2.2" or "1.2.840.10008.5.1.4.1.1.4.4" or "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted). May be present otherwise.
>Frame Acquisition DateTime (0018,9074) 1C The date and time that the acquisition of data that resulted in this frame started. See Section C.7.6.16.2.2.1 for further explanation. Required if Frame Type (0008,9007) Value 1 of this frame is ORIGINAL and the SOP Class UID is not "1.2.840.10008.5.1.4.1.1.2.2" or "1.2.840.10008.5.1.4.1.1.4.4" or "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted). May be present otherwise.
>Frame Acquisition Duration (0018,9220) 1C The actual amount of time [in milliseconds] that was used to acquire data for this frame. See Section C.7.6.16.2.2.1 and Section C.7.6.16.2.2.3 for further explanation. Required if Frame Type (0008,9007) Value 1 of this frame is ORIGINAL and the SOP Class UID is not "1.2.840.10008.5.1.4.1.1.2.2" or "1.2.840.10008.5.1.4.1.1.4.4" or "1.2.840.10008.5.1.4.1.1.128.1" (Legacy Converted).
