Abstract
Systems and methods for estimating the location of a wave source based upon low frequency measurements acquired using multiple receivers. In one aspect, a method for estimating an end range of a radiation beam delivered to a target is provided. The method includes controlling a radiation treatment system to deliver a radiation beam inducing at least one low frequency thermoacoustic wave inside a target, and detecting, using receivers positioned about the target, sonic signals corresponding to the at least one low frequency thermoacoustic wave. The method also includes analyzing the sonic signals to determine differences in times-of-flight associated with different receivers, and estimating an end range of the radiation beam by correlating the differences in times-of-flight. The method further includes generating a report indicative of the end range of the radiation beam.
