# BB Implant Template Query/Retrieve Service Classes

## BB.1 Overview

### BB.1.1 Scope

The Implant Template Query/Retrieve Service Classes define application-level classes-of-service that facilitate access to Implant Template and Implant Assembly Template composite objects.

### BB.1.2 Conventions

Key Attributes serve two purposes; they may be used as Matching Key Attributes or as Return Key Attributes. Matching Key Attributes may be used for matching (criteria to be used in the C-FIND request to determine whether an entity matches the query). Return Key Attributes may be used to specify desired return Attributes (what elements in addition to the Matching Key Attributes have to be returned in the C-FIND response).

### Note

Matching Keys are typically used in an SQL 'where' clause. Return Keys are typically used in an SQL 'select' clause to convey the Attribute values.

Matching Key Attributes may be of Type "required" (R) or "optional" (O). Return Key Attributes may be of Type 1, 1C, 2, 2C, 3 as defined in PS3.5.

### BB.1.3 Query/Retrieve Information Model

In order to serve as an SCP of the Implant Template Query/Retrieve Service Class, a DICOM AE possesses information about the Attributes of a number of Implant Template or Implant Assembly Template composite SOP Instances. The information is organized into an Information Model. The Information Models for the different SOP Classes specified in this Annex are defined in Section BB.6.

### BB.1.4 Service Definition

Two peer DICOM AEs implement a SOP Class of an Implant Template or Implant Assembly Template Query/Retrieve Service Class with one serving in the SCU role and one serving in the SCP role. SOP Classes of the Implant Template and Implant Assembly Template Query/Retrieve Service Classes are implemented using the DIMSE-C C-FIND, C-MOVE and C-GET services as defined in PS3.7.

An SCP of this SOP Class shall support Level-2 conformance as defined in Section B.4.1.

The semantics of the C-FIND service are the same as those defined in the Service Definition of the Basic Worklist Management Service Class.

The semantics of the C-MOVE service are the same as those defined in the Service Definition of the Query/Retrieve Service Class, with the exception that there is only one level of retrieval.

The semantics of the C-GET service are the same as those defined in the Service Definition of the Query/Retrieve Service Class, with the exception that there is only one level of retrieval.
