Tissue harmonic imagingとは

WebFeb 1, 2001 · Abstract. Tissue harmonic imaging (THI) is a new gray-scale sonographic technique that improves image clarity. Harmonics form within the insonated tissue as a consequence of nonlinear sound propagation. Imaging with endogenously formed harmonics means that the distorting layer of the body wall is traversed only once by the … WebNative™ 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. The improved image quality leads to higher diagnostic …
