Reconstructing initial pressure and speed of sound distributions simultaneously in photoacoustic tomography
Miika Suhonen, Felix Lucka, Aki Pulkkinen +3
Image reconstruction in photoacoustic tomography relies on an accurate knowledge of the speed of sound in the target. However, the speed of sound distribution is not generally know…
