| Summary: | Current attempts in understanding the photoacoustic signal characteristic of various shapes of nanoparticles is mostly
performed through numerical simulations. However these computational methods are very time consuming, costly and
complicated. Thus there is a need for an easy and fast simulation technique to understand the photoacoustic signal
generated from various shapes of nanoparticles. k-Wave is a MATLAB based simulation toolbox to simulate
photoacoustic signal given the initial pressure distribution of the target object. In this work, we used k-Wave simulation
to understand the photoacoustic signal generated from various shapes of nanoparticles. Seven shapes of nanoparticles are
created mainly sphere, cylinder, hollow cylinder, cube, hollow cube, triangle, and star. A point sensor (ultrasound
detector) is used to detect the photoacoustic waves generated from different shapes of nanoparticles. The photoacoustic
signal generated by different shapes of nanoparticles is captured and processed for further analysis to see their frequency
content. |
