Tissue harmonic echo
WebNational Center for Biotechnology Information WebSummary Native™ Tissue Harmonic Imaging is a new way of ultrasound image processing that addresses the difficult-to-image patient. By using a Gaussian shaped transmit pulse it is possible to separate from the returning echo the harmonic component without overlapping with fundamental reflections.
