Coded Harmonic Imaging (CHI)
Description
Harmonic imaging utilizes Digitally Encoded Ultrasound (DEU).
Coded Harmonics enhances near field resolution for improved
small parts imaging as well as far field penetration.
Adjusting
To activate Coded Harmonic imaging,
Press
Harmonics
.
NOTE:
Multi frequency is not active when the image is frozen.
Values
On/Off. See Chapter 17 for probe availability. `CHI' appears next
to the active probe indicator.
NOTE:
Changing multi frequency resets those parameters which are
presettable by frequency to their preset values for the current
harmonic frequency.
Multi frequency values are returned to the factory or user preset
value when you change the following: Probe, Exam Category,
Application, or New Patient.
Benefits
Coded Harmonics diminishes low frequency high amplitude
noise and improves imaging technically difficult patients. Coded
Harmonics may be especially beneficial when imaging isoechoic
lesions in shallow-depth anatomy in the breast, liver, and hard-
to-visualize fetal anatomy. Coded Harmonics may improve B-
Mode image quality without introducing a contrast agent.
Bioeffects
Activating multi frequency mode may change the TI and/or MI.
Observe the output display for possible effects.
