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
difficult-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.
Tap THI again to exit the imaging, and THI disappears from the screen.
NOTE
•
The system automatically optimizes certain parameters (B-mode gain, frequency
and frame rate) upon enabling THI.
•
Compared to the B-mode imaging, THI improves image resolution but decreases
the frame rate. Therefore, you should make an optimal balance when choosing an
imaging mode.
•
THI is only available with compatible probes.

5 Panoramic Imaging
Panoramic imaging is an imaging process that produces a panoramic image by using
certain probes. The panoramic image provides sequentially and individually aligned 2D
images on a static image. The 2D images are real-time, showing their anatomical context
of an adjacent structure. Panoramic imaging allows you to display, view and measure a
new stitched image constantly.
