We introduce a new method of calibration based on the time-of-flight measurements between sensors when the enclosed medium is homogeneous. Bounds on the reconstruction errors are proven and results of simulations mimicking a scanning device are presented.ultrasound tomographycalibrationmatrix completionmulti-dimensional scalingNCCR-MICSNCCR-MICS/EMSPtext::conference output::conference proceedings::conference paper
