Patent ID: 8500644

Claim:
A method for imaging a region of interest (ROI) within a body, the method comprising: applying ultrasound energy to the ROI; receiving ultrasound data for the ROI in response to the applied ultrasound energy; executing a moving window analysis on the received ultrasound data to generate a plurality of windows of information; applying a Renyi entropy signal receiver to each of the generated windows to generate Renyi entropy data, wherein the Renyi entropy signal receiver is defined as: I f ⁡ ( r ) = 1 1 - r ⁢ log ⁡ [ ∫ f m ⁢ ⁢ i ⁢ ⁢ n f ma ⁢ ⁢ x ⁢ ρ f ⁡ ( y ) r ⁢ ⅆ y . ] , wherein ρ f (y) defines a density function of a signal f(t), wherein f min is a minimum of f (t) and f max is a maximum of f(t), and wherein r is an adjustable parameter; and presenting an image of the ROI based on the Renyi entropy data.
