Ultrasonic tissue characterization parameter presentations in three dimensions

Three-dimensional ultrasonic Nakagami imaging for tissue characterization.

The two-dimensional (2D) Nakagami image complements the ultrasound B-scan image when attempting to visualize the scatterer properties of tissues. The resolution of the Nakagami image is lower than that of the B-scan image, since the former is produced by processing the raw envelope data using a 2D sliding window with side lengths typically corresponding to three times the pulse length of the in...

One-parameter superscaling in three dimensions

Numerical and analytical details are presented on the newly discovered superscaling property of the energy spacing distribution in the three dimensional Anderson model. PACS: 71.30.+h, 72.12.Rn, 05.40.+j .

A Two-Parameter Model for Ultrasonic Tissue Characterization with Harmonic Imaging

Over the past few decades, researchers have developed several approaches such as the Reference Phantom Method (RPM) to estimate ultrasound attenuation coefficient (AC) and backscatter coefficient (BSC). AC and BSC can help to discriminate pathology from normal tissue during in-vivo imaging. In this paper, we propose a new RPM model to simultaneously compute AC and BSC for harmonic imaging and a...

LABORATORY INVESTIGATION TISSUE CHARACTERIZATION Ultrasonic tissue characterization: detection of acute myocardial ischemia in dogs

Ultrasonic tissue characterization is a new area of investigation in the field of cardiac ultrasound. The amplitude and frequency of the ultrasound signal are normally altered as the signal penetrates through tissue. It is assumed that the amplitude distribution and frequency shift of diseased or edematous tissue are different than those of normal tissue. A statistical approach to the analysis ...
