The quest to extract rock properties from seismic images has resulted in a growing interest in full waveform inversion and imaging. This study applies frequency-domain visco-acoustic waveform inversion and reverse-time imaging to synthetic and laboratory data. The laboratory data for a crosshole configuration is obtained with a two-axes computer-controlled scanning system. Broadband 200 kHz data is obtained using a piezofilm source and detector in a water tank with suspended acrylic bars.
