Harmonic Imaging
Tissue Harmonic Imaging (True Echo Harmonics – TEH)
True Echo Harmonics (TEH) is B-K Medical’s trademarked name for tissue
harmonic imaging. Using it can reduce noise and improve the clarity of the
ultrasound image.
In normal B-mode imaging, the transducer uses essentially the same frequency range
for both transmitting and receiving. In harmonic imaging, the image is created by
receiving higher frequencies (harmonics) that are multiples of the transmitted
frequency (f). Tissue harmonic imaging in the Pro Focus is based on the 2nd
harmonic (2f) spectrum.
