 This project is a Python implementation of v1.4.0 of the [MATLAB toolbox k-Wave](http://www.k-wave.org/) as well as an
 interface to the pre-compiled v1.3 of k-Wave simulation binaries, which support NVIDIA sm 5.0 (Maxwell) to sm 9.0a (Hopper) GPUs.

 # Defining A Sensor Using An Array Transducer Example

+
 This example provides a demonstration of using the kWaveArray class to define an array transducer with 20 arc-shaped elements which is then used as a receiver array. It builds on the Defining A Source Using An Array Transducer Example.

 This example provides a demonstration of using the kWaveArray class to define an array transducer with three arc-shaped elements without staircasing errors.
 
 For a more detailed discussion of this example and the underlying techniques, see E. S. Wise, B. T. Cox, J. Jaros, & B. E. Treeby (2019).

 This example provides a demonstration of using the kWaveArray class to define a linear array transducer with 15 rectangular elements. Electronic focusing is then used to transmit an ultrasound pulse. It builds on the [Defining A Source Using An Array Transducer Example](../at_array_as_source/).

 This example illustrates how k-wave-python can be used for the simulation of B-mode ultrasound images (including tissue harmonic imaging) analogous to those produced by a modern diagnostic ultrasound scanner.
