Abstract: A method and system optimize a thermoacoustic transducer functionality that is utilized in a thermoacoustic imaging system. The method and system select a pre-determined transducer geometry for the thermoacoustic imaging system, utilize the thermoacoustic imaging system with the pre-determined transducer geometry to generate at least one impulse in a field of view, acquire data from the impulse, reconstructing the data to generate N-dimensional impulse responses based upon respective channel responses, respective view responses, and a function of the acquired data, utilize the N-dimensional transforms for each image to generate a value for the pre-determined transducer functionality, and utilize the value for the pre-determined transducer functionality to determine an optimum thermoacoustic transducer functionality.

Abstract: A method and system for reconstructing a thermoacoustic image that utilizes the steps of directing radio frequency (RF) energy pulses generated by an RF source into a tissue region of interest; detecting, at each of a plurality of views along a scanning trajectory of a transducer element array about the region of interest, acoustic signals generated within the region of interest in response to the RF energy pulses and generating thermoacoustic data; applying at least one correction kernel to the thermoacoustic data; and after the at least one correction kernel has been applied to the thermoacoustic data, reconstructing a thermoacoustic image therefrom.
