Selecting a Transducer

Transducers

8 Transducers
The transducer that you select is the most important factor in image quality. Optimal imaging
cannot be obtained without the correct transducer. The system is optimized for use based on
your transducer selection.
The system limits patient contact temperature to 43 degrees Celsius, and acoustic output
values to their respective U.S. Food and Drug Administration limits. A power-protection circuit
protects against over-current conditions. If the power monitor protection circuit senses an
over-current condition, then the drive voltage to the transducer is shut off immediately,
preventing overheating of the transducer surface and limiting acoustic output. Validation of the
power protection circuit is done under normal system operation.
Non-TEE transducers are rated minimum IPX7 in accordance with IEC 60529. Transesophageal
transducers are rated minimum IPX1 (control area) and IPX7 (endoscope area) in accordance
with IEC 60529.
WARNING
All TEE transducers are designed to be defibrillator safe in accordance with IEC 60601-1.
Nevertheless, always remove the transducer from the patient before defibrillation.
WARNING
To limit potential harm when scanning neonatal, pediatric, and medicated patients, minimize
the time spent imaging at temperatures above 41°C (106°F).
Selecting a Transducer
When the system is turned on, the system initializes the last active transducer. If that
transducer is not connected, the system initializes the transducer that is connected to the
leftmost connector, unless you have defined another transducer as the default transducer. If
