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 41 degrees Celsius for all
transducers, and limits acoustic output values to their respective U.S. Food
and Drug Administration limits for all transducers. 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.
WARNING
Use caution when scanning neonatal, pediatric, and medicated patients by
minimizing the time spent imaging at temperatures above 41°C (106°F).
CAUTION
Mechanical transducers, such as the 3D6-2, should be operated only at normal
operating temperatures (50°F to 104°F or 0°C to 40°C). Operating a
mechanical transducer at lower temperatures can damage it.
NOTES
• Using excessive pressure when scanning with a motorized transducer can
cause the acoustic lens to deform and impede the moving array, resulting
in an error message. When pressure is reduced, the system recalibrates
the transducer, and imaging resumes. Avoid excessive pressure when
using a motorized transducer.
• If the L17-5 transducer is selected before using the C9-4 transducer,
reducing the sector angle with SonoCT imaging on and then steering to
the right results in corrupted display data and gain mismatch on the right
side of the image.
