Accurate reconstruction of temperature distribution with flexible element arrangement ultrasonic CT

In this paper, we find conditions that reconstruction of temperature distribution gets worse when the ultrasonic transceivers (transmitter and receiver) are arranged flexibly. We discovered the minimum number of the ultrasonic transceivers required for successful reconstruction and proved that the number is correct. Moreover, we proposed arrangement of the number in accordance with parity of pixel division. As a result of simulation with these arrangements, the reconstruction succeeded.
