How Tissue Harmonic and Spatial Compound Imaging Alter Ultrasound Images

Tissue harmonic imaging reduces clutter and enhances shadowing by using endogenous high-frequency components; spatial compound imaging cuts noise and speckle by averaging multiple angles. Combined, they improve ultrasound image quality and modify artifact appearance.

• Tissue harmonic imaging uses harmonic frequencies generated in tissue to construct images, mitigating clutter and accentuating shadowing artifacts.
• Spatial compound imaging acquires images from different angles and averages them, reducing noise and speckle.
• These techniques can be combined to improve image quality in complementary ways and alter artifact appearance.
