Abstract
A method for estimating an ultrasonic attenuation parameter of a region in a medium includes a transmission step in which at least one pulse is transmitted in the medium by a transducer, and a reception step in which data is acquired by a transducer in response to the pulse. The method includes a processing step in which the data is processed by the processing unit for providing backscattered acquisition data of the region, and a function determination step in which an auto-correlation function of the backscattered acquisition data is determined which is a function of depth in the spatio-temporal domain, the autocorrelation function being determined at a lag of zero. The method includes an attenuation estimation step in which an ultrasonic attenuation parameter is estimated based on said auto-correlation function. The method is implemented by a processing unit associated to at least one ultrasound transducer.
