Description

Two types of “harmonic imaging” techniques are widely used in ultrasound diagnosis. One type is tissue harmonic imaging, which uses higher harmonics generated on propagation of ultrasound through tissue and improves lateral resolution and clarity in B-mode images. The other is contrast harmonic imaging with gas microbubble contrast agents, which can detect tumor vessels and tissue perfusions. The basic physics of both types is explained here.
