1>3D Time Reversal Reconstruction For A Spherical Sensor Example</h1>

<p>This example demonstrates the use of k-Wave for the time-reversal reconstruction of a three-dimensional photoacoustic wave-field recorded over a spherical sensor. 
The sensor data is simulated and then time-reversed using <code><a href="kspaceFirstOrder3D.html">kspaceFirstOrder3D</a></code>. 
It builds on the <a href="example_pr_2D_tr_circular_sensor.html">2D Time Reversal Reconstruction For A Circular Sensor</a> and <a href="example_
