Table C.8-100c. Functional MR Macro Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Functional MR Sequence | (0018,9621) | 1 | Identifies the Functional parameters of this frame. Only a single Item shall be included in this Sequence.
>Settling Phase Frame | (0018,9624) | 1C | Identifies if the frame is part of a Functional MR settling phase. All frames with the same combination of Stack ID (0020,9056) and Temporal Position Index (0020,9128) shall have the same value. Enumerated Values: YES NO Required if Functional Settling Phase Frames Present (0018,9622) is YES.
>Functional Sync Pulse | (0018,9623) | 1 | The date and time of the Functional Sync Pulse for this frame. See Section C.8.13.5.15.1

###### C.8.13.5.15.1 Functional Sync Pulse

Functional Studies require synchronization between the Acquisition Modality and external devices to coordinate paradigm presentation by an external system with image acquisition. It is required that the Acquisition Time Synchronized (0018,1800) shall be "Y".

The Functional Sync Pulse (0018,9623) is the date-time stamp of the pulse at the start of the acquired volume(s) in the SOP Instance. All frames with the same combination of Stack ID (0020,9056) and Temporal Position Index (0020,9128) share the same time stamp.
