Adaptive imaging using an optimal receive aperture size.
Sidelobe contribution from off-axis targets degrades image quality in a coherent array imaging system. In ultrasound imaging, focusing errors resulting from sound-velocity inhomogeneities in human tissue--also known as phase aberrations reduce the coherence of the received signals and elevate the si...
Ultrasound attenuation imaging using compound acquisition and processing.
A method that combines both spatial and frequency compounding is described for measuring attenuation in tissue. The technique applies a reference phantom to account for imaging system dependencies of echo signals. Emphasis is given to local attenuation estimates, to reduce the variance of the attenu...
Tradeoffs in elastographic imaging.
This paper presents the tradeoffs in elastographic imaging. Elastography is viewed as a new imaging modality and presented in terms of three fundamental concepts that constitute the basis for the elastographic imaging process. These are the tissue elastic deformation process, the statistical analysi...

Subharmonic imaging with microbubble contrast agents: initial results.
The subharmonic emission from insonified contrast microbubbles was used to create a new imaging modality called Subharmonic Imaging. The subharmonic response of contrast microbubbles to ultrasound pulses was first investigated for determining adequate acoustic transmit parameters. Subharmonic A-line...
Validation of theoretical diffraction correction functions for strongly focused high frequency ultrasonic transducers.
These results are compared to a recently-published theoretical model. Excellent agreement between the experiment and theory is achieved. No statistically-significant difference in mean backscattered power is found between the experimental and theoretical approaches. The use of a simple normalization...
Effects of tissue anisotropy on the spectral characteristics of ultrasonic backscatter measured with a clinical imaging system.
We report the effects of inherent tissue anisotropy on the spectral properties of backscattered ultrasound when measured with a commercially-available imaging system. We insonified five specimens of bovine tendon immersed in a water tank and rotated in 10 degrees increments while being imaged with a...
Multiple-transducer scheme for scanning tomographic acoustic microscopy using transverse waves.
We propose a new type of multiple-transducer scheme with functions of multiple-angle and multiple-frequency tomography for scanning tomographic acoustic microscopy (STAM) using transverse waves. We review the data acquisition system and mode conversion of the acoustic waves for STAM and the multiple...
Doppler Ultrasound Simulation Model for Pulsatile Flow with Nonaxial Components
Time reversal focusing applied to lithotripsy.
We investigate the feasibility of a piezoelectric shock wave generator in which the focal zone is moved electronically to track the stone during a lithotripsy treatment. We show that TRM allows us to obtain sharp focusing on one bright point of the stone. The time of flight profile is then determine...
