(.):  The paper presents a method for calibration of planar circular arrays of sensors used in ultrasound tomography, which enables the estimation of sensor coordinates and signal reception/transmission delays. The method uses an ultrasound wave propagation model and is based on the triangulation approach to identify the model parameters. At each iteration of the method, the estimates of coordinates and delays are recalculated separately from each other by solving systems of linear equations of low dimensionality. Simulation over synthetic data demonstrated high efficiency and accuracy of the approach: It is noise-resistant and is capable of operating in diverse conditions, including non-ideal model of ultrasound wave propagation. The proposed approach can be easily scaled to calibrate devices with large nuber of sensors, which makes it relevant to correct industrial practical implementation. This method can significantly improve the accuracy of ultrasound imaging results, making it a valuable tool for a variety of applications, such as medical diagnostics, robotics, etc.
