Design of a Novel High Frequency Ultrasound Annular Array
The design of a novel 50MHz 7-elment annular array is described. Equal-width electrodes are deposited on the rear face of piezoelectric layer to form a kerfless array, instead of mechanical cutting. Compared with equal-area designs, much better performance is achieved by the novel design. The cross talk is down to -20dB, the -6dB bandwidth and insertion loss are 41% and 18dB, respectively. The ...
متن کاملUltrasound Elasticity Imaging System with Chirp-Coded Excitation for Assessing Biomechanical Properties of Elasticity Phantom
The biomechanical properties of soft tissues vary with pathological phenomenon. Ultrasound elasticity imaging is a noninvasive method used to analyze the local biomechanical properties of soft tissues in clinical diagnosis. However, the echo signal-to-noise ratio (eSNR) is diminished because of the attenuation of ultrasonic energy by soft tissues. Therefore, to improve the quality of elastograp...

متن کاملCoded Excitation Methods for Ultrasound Harmonic Imaging
Coded excitation methods offer the potential for improving the SNR without increasing the peak transmitted power and without sacrificing resolution. Our study examines the potential application of coded waveforms, specifically FM chirps, in harmonic imaging. Such a system, in which nonlinear echoes from tissue are used to form the image, requires the extraction and compression of the second har...
متن کاملBarker-coded excitation in ophthalmological ultrasound imaging.
High-frequency ultrasound is an attractive means to obtain fine-resolution images of biological tissues for ophthalmologic imaging. To solve the tradeoff between axial resolution and detection depth, existing in the conventional single-pulse excitation, this study develops a new method which uses 13-bit Barker-coded excitation and a mismatched filter for high-frequency ophthalmologic imaging. A...
