摘要：
An embodiment for analyzing a body-part of a patient is proposed. A corresponding data-processing method includes the steps of providing a sequence of input images representing the body-part over an analysis period, each input image including a set of input values each one being indicative of a response to an interrogation signal of a corresponding location of the body-part at a corresponding acquisition instant included in the analysis period, associating an analysis function of time with each one of a set of selected locations, the analysis function modeling a trend of the input values of the selected location in the sequence of input images, and providing a reference function of time for the analysis functions； in an embodiment, the data-processing method further includes comparing the analysis function of each selected location with the reference function to determine a polarity trend representing a trend over the analysis period of a polarity of a divergence between the analysis function of the selected location and the reference function, and creating a parametric image including a parametric value for each selected location, the parametric value being indicative of the polarity trend of the selected location.
