Phase Reversed Image Reconstruction Method of Industrial Ultrasonic CT

摘要：

Based on various ultrasonic CT technology that have been developed, a new type ultrasonic CT is proposed. One array transducer is used, detected at only one or two position on a specimen, and then created the received signal list array. With the received signal list array, the authors obtained a new algorithm, named virtual scan, which reconstructed the image of the specimen from both the amplitude and the phase of a received signal. Dealing the entire signal array with this method, the authors got a pretty image of the specimen, so the new method is effective in the situation of the experiments.
