11.1.4 Harmonic Imaging
Tissue Harmonic Imaging (THI) uses the harmonic frequencies generated by tissue. The fundamental transmit
frequency results in a harmonic frequency echo. The harmonic frequency received from the tissue is a multiple
of the fundamental transmit frequency. The fundamental and any accompanying artifacts are missing from the
harmonic frequency that the system receives. The artifact reduction, and the concomitant reduction in haze and
clutter, increases contrast resolution and improves border delineation. THI is useful in difcult-to-image patients.
In real time scan of B mode, tap
THI
on the touch screen to enable the THI mode, and
THI or PHI
appears at
the lower left corner of the screen. Optimize the image the same way you did in the B mode.
