Abstract :
Calculating and visualizing the sound field of transducers is a key task in the development of most ultrasound applications. In most cases it is sufficient to calculate the directivity pattern or a plane slice of the sound field using the point source synthesis method. To date no freeware tool is available which is able to simulate the sound field for arbitrary rectangular transducer array matrices for different excitation signals. The developed ”Transducer Array Calculation GUI” (TAC) includes phase- and frequency-informations as well as apodization to calculate sound fields of various transducer configurations. TAC also offers to include the medium attenuation and transducer´s electrical impedance characteristics. Our software supports fast and realistic transducer engineering and it is open source.
