摘要：

In this paper, we propose a new, acoustic computerized tomography (A-CT) method using reflection. This method is alternate optimization for measuring, the temperature distribution in a cylindrical space. The A-CT method using reflection includes two inverse problems, namely, the back projection of Radon transform and the division of times of flight (TOFs) of reflected sounds into TOFs of pre-reflection and post-reflection. The TOF estimation problem requires the temperature distribution. To solve this problem mathematically. alternate optimization is applied to the A-CT method using reflection. Simulation results indicate HIM our new, A-CT method using.(1 reflection is useful for measuring the temperature distribution ill a cylindrical space. [DOI: 10.1143/JJAP.47.3967]
