ABSTRACT

In this paper, the current situation of acoustic CT in temperature field measurement is summarized. Some typical construction algorithms are analyzed, and their shortcomings are given. In order to solve the problem of few acoustic projection data, the method of division of plane pixels with regularization is proposed.
