Broadband Harmonics

Broadband Harmonics

Broadband harmonics uses the broadband and large amplitude transmission typically represented by compound impulse waveform transmission. The technique of removing the fundamental wave components by phase modulation is used. Compared with phase-modulated harmonics (based on differences between two frequencies elsewhere used), the broadband harmonics assure a high and wide frequency distribution and generates images with straightforward sounds.

The compound impulse transmission technique for generating broadband signals is used in not only harmonic imaging, but in fundamental wave imaging also.

Harmonic imaging by Broadband Harmonics technology delivers sensitivity and resolution comparable to those of fundamental imaging. In addition to reducing side lobes and multiple echoes, more detailed image information and much higher penetration in deeper areas are achieved.
