[en] Seismic borehole tomography has become a standard method and is routinely used for the detection of karstic phenomena and the delineation of geological structures. Seismic tomography is believed to be the seismic method promising the most accuracy and reliability. Remaining uncertainties due to a non-zero residual is often neglected. However, the quality of the photographs is very high. We present tomographic inversion results in the signal-to-noise ratio of the first arrival time. This new data quality weighting scheme is assumed to provide more reliable inversion results. Information about the reliability of the tomogram provided with the geophysicist interpretation. The effect of the data quality weighted inversion is studied on a field data set.
