Parametric images based on dynamic behavior over time

A computer program product including a non-transitory computer readable medium embodying a computer program, the computer program including code means directly loadable into a working memory of a data-processing system thereby configuring the data-processing system to perform a data-processing method for analyzing a body-part of a patient, the data-processing method including 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,
• providing a reference function of time for the analysis functions,
• 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.
