A Sound-Speed imaging method based on ray tomography

Abstract

Ultrasonic tomography has a wide range of applications in the field of formation profiling, medical CT and other fields. This paper introduces an iterative algorithm based on acoustic travel time tomography. The computer simulation results and experimental results verify that the imaging performance of this algorithm has better resolution and imaging accuracy than traditional SIRT or ART algorithms. And the artifact caused by the limited viewing angle is effectively suppressed.
