##### C.8.24.3.4 Transducer Description

The following elements together describe the type of transducer used to acquire the image. These are characteristics of the transducer itself rather than its specific use in the acquisition of this image. In other words, these attribute values are determined from the construction and design of the transducer and a given transducer generally has the same values of these attributes in every image it is used to create.

- Transducer Scan Pattern Code Sequence (0018,9809)

The shape of the acoustic scan field the transducer is capable of.

- Transducer Geometry Code Sequence (0018,980D)

The physical scan aperture from which acoustic pulses are emitted and received.

- Transducer Beam Steering Code Sequence (0018,980E)

The method used to steer acoustic beam.

- Transducer Application Code Sequence (0018,980F)

The placement on the subject for which the transducer is designed.

Each probe model has a unique set of values of these attributes. For example, these sample probes have the following characteristics, which are encoded in the attributes above:
