Computerized Ultrasonic Reflectivity Tomography by Transmitter/Receiver Array Transducers at Circumference Points

概要
- 論文の詳細を見る
Computerized ultrasonic reflection-type tomography provides a means of obtaining the acoustic reflectivity image of an object. In this paper, fixed-array transducer elements are considered with the aim of real-time data acquisition. However the number of elements is restricted because of space limitation for the transducer arrangement. Thus, streak-like artifact is unavoidably caused by the use of very few observation views. To cope with this problem, correction of streak artifact is employed in the iteration procedure of the algebraic reconstruction technique. The validity of the method using synthesized data for weak scattering cylindrical test objects is investigated. Results show that relatively good images are obtained using a restricted number of fixed transducers.
