Study of reconstruction methods for temperature and wind velocity using ultrasonic CT
Abstract:In this paper the basis of ultrasonic CT is stated. And the mainstream methods for measuring temperature and wind velocity are introduced, including the back projection methods, the interative methods and the solutions of matrix equation. This paper summarizes the domestic and foreign research present situation. Computer simulation is carried out using MATLAB to estimate the performance of these methods. As the complexity of ultrasonic propagation and the variety of ultrasonic CT application, there is much space to develop the reconstruction algorithm . And a possible future trend that might lead to measuring both temperature and wind velocity simultaneously.
Keywords: ultrasonic CT temperature wind;reconstruction methods;TOF
