harmonic imaging

harmonic imaging

Ultrasound scanning that records higher harmonics as well as the fundamental frequency of the transducer; better resolution and fewer artifacts are found compared with results using conventional scans.

Both the eus probes and the standard probes are designed for the modalities of real-time elastography and contrast harmonic imaging (chi) for contrast-enhanced ultrasound imaging (ceus, Low and high mi).
Harmonic imaging leads to improved resolution and reduced reverberation and near-field artifacts.
Aim: This study assessed the ability of tissue harmonic imaging ultrasound combined with power Doppler ultrasound in the detection of childhood febrile urinary tract infections in comparison with the gold standard reference method: Tc-99m dimercaptosuccinicacid renal cortical scintigraphy.
The underlying principles of contrast harmonic imaging are as follows: when exposed to ultrasound beams, microbubbles in the contrast agent are disrupted or resonate and release many harmonic signals [14].
