Abstract
A solution for diagnostic applications is proposed. Particularly, a corresponding diagnostic system includes means (903-906) for providing (A1-A3) a plurality of input signals representative of a body-part being perfused with a contrast agent over time, each input signal being indicative of a response to an interrogating stimulus of a corresponding location of the body-part possibly including the contrast agent, means (909-930) for generating (A4.1-A4.3) a plurality of filtered signals from selected input signals of selected locations, each filtered signal at each instant over time being generated from a corresponding selected input signal according to a portion of the selected input signal including said instant, and means (933-939) for monitoring (A4.4-A4.6) each filtered signal to detect a peak in the response to the interrogation stimulus of the corresponding selected location, the peak being detected in response to the fulfillment of a stability condition by a corresponding portion of the filtered signal.
