Harmonic Fusion Imaging
Introduction
Harmonic Fusion for tissue provides improved visualization of the endocardial
border, particularly with patients who are difficult to image. Harmonic Fusion
imaging activates harmonics for a 2D image only—all Doppler modes remain at
the fundamental frequency.
Following are some Harmonic Fusion guidelines:
• You are required to use a harmonics-ready transducer, such as the s3, s4, s8,
11-3L, c3540, OmniPlane III, or x4.
• When using Harmonic Fusion imaging, the Power control on the secondary
touch panel affects transmit power.
• A maximum frame rate of 30 Hz (25 Hz for PAL systems) is used. There are
exceptions, such as with the s3 transducer, which allows higher frame rates
in Harmonic Fusion setting 5.
• Harmonic Fusion is available with cardiac exam presets, the transcranial
preset, and the following abdominal presets: abdominal, vascular
abdominal, small parts, and renal. Harmonic fusion is also available with
vascular-carotid, PV, low-extremity, and upper-extremity exams and presets.
The available exams and presets depend upon the transducer type.
In Harmonic Fusion imaging, the Harmonic Fusion icon replaces the Frequency
Fusion icon. The selection is indicated by a circle around the setting. For more
information, see “Icons” on page 7-10.
NOTE For information about Harmonic Fusion in Live-3D and BiPlane imaging modes,
