Automatic sound speed selection in photoacoustic image reconstruction using an autofocus approach

Treeby, Bradley; Varslot, Trond; Zhang, Edward; Laufer, Jan G; Beard, Paul


The reconstruction of images in photoacoustic tomography is reliant on specifying the speed of sound within the propagation medium. However, for in vivo imaging, this value is not normally accurately known. Here, an autofocus approach for automatically selecting the sound speed is proposed. This is based on maximizing the sharpness of the reconstructed image as quantified by a focus function. Several focus functions are investigated, and their performance is discussed. The method is...[Show more]
