Abstract
This paper is concerned with reconstruction of ultrasonic tomography from time-of-flight projections. The use of conventional CT methods, assuming straight line propagation, generally yields to insufficient quality images. In order to improve the reconstruction, the refraction phenomenon has to be taken into account. Some ray tracing and reconstruction methods are compared then implemented and tested on simulated objects. Finally, reconstructed images are displayed.
