3rd Harmonic Imaging
AI-enabled innovation for more detail and depth
3rd Harmonic Imaging (3-HI) is a technology that utilizes the frequency components of the ultrasound beam at three times the transmitted frequency.
Developmentally, to extract the 3rd harmonic components from the huge quantity of received signals, an AI filter for 3rd harmonic was designed using deep learning that allows the effective extraction and utilization of the 3rd harmonic signal.
Using the 3rd harmonic sharpens the received beam, reduces multiple reflections and sidelobes, and achieves B-mode images with less noise in the vessel lumen and clearer tissue structures around the vessel.

Clinical Images
The use of the 3rd harmonic component reduces artifacts and increases the distance resolution due to broader frequency band of transmission and reception.
