Abstract :
The tomographic images constructions were done with an aid of LSP (linear least squares problem). Proposed methods were illustrated with a numerical simulation results.In this paper we have extended the idea of measurement of an average speed flow to a measuring a speed profile in a cross section or in coaxial surfaces of the pipe. This idea directly leads to a multipath ultrasonic tomography.
