TL;DR: In this article, the authors proposed a nonlinear adaptive thresholding of received echo wavelet transform coefficients to reduce the signal-dependent noise in a coherent imaging system signal, such as in medical ultrasound imaging.

TL;DR: A reconfigurable linear array of sensors (e.g., optical, thermal, pressure, ultrasonic) as discussed by the authors allows the size and spacing of the sensor elements to be a function of the distance from the beam center.

TL;DR: In this article, the authors propose an array of sensors and a multiplicity of bus lines, each sensor being electrically connected to a respective bus line and comprising a respective multiplicity groups of micromachined sensor cells, the sensor cell groups of a particular sensor being coupled to each other via the bus line to which that sensor is connected.

TL;DR: In this paper, an ultrasound imaging method for detecting a target region of altered stiffness is provided, which consists of delivering at least one reference pulse to the target region to detect an initial position of the target regions, delivering a first pushing pulse having a first value of a variable parameter to a target Region to displace the target Regions to a first displaced position, and delivering a second tracking pulse to detect the second displaced position.

TL;DR: In this article, a transducer array is reduced in number and then selectively located at grid positions in a pattern which reduces the sidelobe levels produced by the array, and a zero sampling technique is used to determine the number of elements on each ring.
