A flexible clinical ultrasound system must operate with different transducers, which have
characteristic impulse responses and widely varying impedances. The impulse response …

A new low-cost ultrasound imaging apparatus that uses optimal-lag pulse shaping filters
was developed. The device comprises a personal computer with MMX CPU, a PCI …

This paper presents an ultrasonic transducer modeling with VHDL-AMS standard (Very High
speed integrated circuits Hardware Description Language–Analog and Mixed Signal) …

We propose an alternative 2 Dimensional acoustical array transducer which enables one to
generate an arbitrary transmitting beam with a very small number of signal channels. The …

Volumetric acoustic imaging is desirable for the visualization of underwater objects and
structures; however, the implementation of a volumetric imaging system is difficult due to the …

Global responses (efficiency, spatial resolution and dynamic range) of piezoelectric
equipment for ultrasonic NDE also depend on the related high-voltage driving-receiving …

There has been an evident increase in the demand for accurate and complex patterns for
particles used in microsized electronic devices. Direct printing technology has been …

Pulse-echo system is the most widely used equipment in non-destructive testing (NDT).
Herein we present the SPICE implementation of a piezo-electric transducer for pulseecho …

La caracterización de un material puede consistir en identificar propiedades del mismo, o
bien, detectar discontinuidades, localizarlas y dar a conocer su naturaleza (poros, fracturas …

Diagnostic ultrasound is being applied to teeth in order to detect cavities, decay, fractures
and even early indication of abscesses. Ultrasonic waves are particularly sensitive to tight …
