## 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 a CT image acquistion Procedure Protocol. A CT Performed Procedure Protocol IOD encodes the details of a procedure that has been performed, and a CT Defined Procedure Protocol IOD specifies details of a procedure that may be used for one or more Procedure Protocols to be peformed 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.
