Log Summary: Rename and Extension of Cardiac Trigger Macro

Type of Modification

Clarification / Addition / Correction



Name of Standard

PS 3.3 - 2004 + Supplement 83



Rationale for Correction:

This change proposal proposes registration of respiratory triggers for respiratory and cardiac/respiratory examination for the Enhanced MR, Spectroscopy, CT multi-frame IOD and Enhanced XA/XRF.

To fulfill the requirements the next extensions and changes are proposed:

1. Extension of the Cardiac Trigger Functional Group.

2. Introduction of a new Functional group for Respiratory Triggers.
