Nowadays, the fast-pace in technology development results in some geophysicial methods becoming alternatives for scientific research. One of them is ultrasound tomography. Some ultrasound tomography applications can be used to research shale gas anisotropy, shear wave and pore pressure. However, many kinds of these methods are still conventional. Therefore, there is a risk that the data from the same sample will be non-uniform from one researcher to another. It is a fact that the conventional method with a couple of transducers for each type of wave takes a long time to finish. An alternative solution for these problems is to create a measuring support tool that can be controlled and managed precisely. In addition to make it more precise, a simple robotic application with a microcontroller and stepper motor can be a practical solution. The results of the conducted research are given in the form of P wave velocity from a sample and its tomography result by using MSIRT method (Modified Simultaneous Iterative Reconstruction Technique). Graphics and tables of comparison concerning measurement error, accuracy and precision between the conventional method and the optimalization are shown. The achieved results by the author are satisfying with the error range decreased by ~50% and good improvement in data quality. Keywords: shale gas, ultrasound tomography, robotic, P wave velocity.
