Abstract：
:This paper presents the influence of ultrasonic beam ray refraction effect on the internal object structure imaging using the ultrasound transmission tomography method (UTT), in parallel ray projection geometry, for ultrasonic pulse run-time measurements. Simulation calculations carried out using specially elaborated software were verified experimentally by means of real measurements on a research set-up for UTT. Simple ways to minimize image distortions caused by the refraction effect were also suggested.
