Abstract

A method of and system of adaptive and robust detection for use in thermoacoustic tomography is provided. The method includes estimating (410) a bipolar acoustic pulse generated by a focal point from multiple thermoacoustic signals using Robust Capon Beamforming, searching (430) for two peaks of the bipolar acoustic pulse within an interval around a calculated arrival time, wherein the interval is determined from an estimated variance of arrival time differences; and calculating (450) a response intensity at the focal point by calculating a peak-to-peak difference of the two peaks.
