### C.34.6 Equipment Specification Module

Table C.34.6-1 contains equipment characteristics for which a Protocol may be considered appropriate.

Table C.34.6-1. Equipment Specification Module Attributes

Attribute Name | Tag | Type | Attribute Description
--- | --- | --- | ---
Equipment Modality | (0008,0221) | 1 | Modality of the equipment to which the protocol is applicable. See Section C.7.3.1.1.1 for Defined Terms.
Model Specification Sequence | (0018,9912) | 3 | Equipment models/versions. See Section C.34.6.1. Zero or more Items shall be included in this Sequence.
>Manufacturer | (0008,0070) | 1 | Manufacturer of the equipment.
>Manufacturer's Related Model Group | (0008,0222) | 3 | Name of a group of related equipment models from the Manufacturer (0008,0070) to which the same protocol applies.
>Manufacturer's Model Name | (0008,1090) | 1C | Manufacturer's model name of the equipment. Required if Manufacturer's Related Model Group (0008,0222) is not present. May be present otherwise.
>Software Versions | (0018,1020) | 3 | Manufacturer's designation of software version of the equipment. See Section C.7.5.1.1.3.
>General Accessory Sequence | (300A,0420) | 3 | Accessories or options that further specify the model. One or more Items are permitted in this Sequence.
>>Accessory Code | (300A,00F9) | 1 | Machine readable identifier for the accessory. E.g., this may indicate accessory equipment such as cardiac gating equipment.
>Device Serial Number | (0018,1000) | 3 | Serial number of a specific device for which the Protocol is intended.

The Protocol details in other Modules may implicitly further constrain the appropriate equipment. For example, the specified hardware may not have the ability to perform acquisitions that satisfy the acquisition parameter constraints, to perform reconstructions that satisfy the reconstruction parameter constraints, or to produce images with the desired characteristics.

#### C.34.6.1 Model Specification Sequence

Each Item in the Sequence, contains multiple Attributes to be satisfied at once. It is only necessary to match one Item in the Sequence. The decision about whether an Item is a suitable match is up to the executing device. The intention is to provide values that would allow a scanner device to identify whether a Protocol is appropriate for it.

### Note

The values may not necessarily match exactly what the scanner would put into corresponding Attributes in Instances it creates.
