Abstract
A perfusion assessment system is proposed. The system includes means for providing an echo-power signal indicative of a perfusion of a contrast agent in a body-part under analysis, the contrast agent being administered as a bolus and undergoing a significant destruction during a passage of the contrast agent in the body-part, means for associating the echo-power signal to a model function including the product between a bolus function indicative of the passage of the contrast agent without said destruction and a reperfusion function indicative of a reperfusion of the contrast agent in the body part following the destruction corresponding to a substantially constant inflow of the contrast agent, and means for estimating at least one perfusion indicator from the bolus function and/or the reperfusion function.
