Original Abstract

The paper presents a method for computing a frequency- and direction-dependent radiation function describing the properties of transducer elements in a transmission ultrasound computed tomography (USCT) system. Such a system consists of a water tank equipped with numerous unfocused ultrasonic transducer elements arranged on a plane circular perimeter of the tank. Each element may be used for emitting or receiving ultrasonic pulse waves that travel through and are scattered in the volume of the tank. USCT systems, still in development, are intended primarily for ultrasonic mammography and seem to be quite promising for this purpose. The presented method calculates a common directivity function and individual sensitivities of all transducer elements (in both, emitting and receiving modes). The calculation is based on solving a large set of log-linearized equations. At the end of this paper, it is shown that the model can be easily extended to include some apriori information about the USCT system.
