## A.82 Procedure Protocol Information Object Definitions

Procedure Protocol Information Object Definitions (IODs) encode the details of procedure protocols.

Separate IODs are defined for different types of Procedure Protocol, such as an image acquisition Procedure Protocol. A Performed Procedure Protocol IOD encodes the details of a procedure that has been performed, and a Defined Procedure Protocol IOD specifies details of a procedure that may be used for one or more Procedure Protocols to be performed in the future.

### A.82.1 CT Performed Procedure Protocol IOD

#### A.82.1.1 CT Performed Procedure Protocol IOD Description

The CT Performed Procedure Protocol IOD describes acquisition and reconstruction protocol parameter values used during a specific performed CT procedure.

#### A.82.1.2 CT Performed Procedure Protocol IOD Entity-Relationship Model

This IOD uses the E-R Model in Section A.1.2, with only the Procedure Protocol IE below the Series IE.
