Abstract

By expressing the region in the wavelet sampling model, it is possible to reconstitute the sound-velocity distribution from the small number of propagation time. The small-scale experimental system for the demonstration was constructed. The effectiveness was confirmed by simulation and experiment. In addition, it was possible to obtain reconstitution image of which the approach accuracy is good by applying the triangular sampling to the sampling technique.
