The scanning algorithm suitable for the arbitrary construction arrays

Abstract

This paper explores the scanning algorithm which can be employed in non-destractive testing and medical investigations where arrays are used. Nowadays the testing systems are equipped with very high speed processors and data transfer systems but sometimes the systems are limited by the used power and the amount of data transmitted from system. So using a smaller number of excitation sequences the arrays systems can be exploited in the application where power consumption or the bandwidth of the transmitted media are critical.
The data collection method for the ultrasonic array was described in the previous studies [5]. To prove the proposed data collection method the experiments were carried out. The algorithm allows us to use a minimum number of the exited elements of the array, while the scanning resolution can be the same like in the single point focusing case.
