Method and system for non-invasive quantification of tissue perfusion obtainable by a destruction-reperfusion process that provide a signal representative of local agent concentration during reperfusion, by deriving at least one local tissue perfusion value. The system is configured to adjust or relate function of time with S-shape characteristics to the signal proportional to the local agent concentration during reperfusion, and making a correspondence between at least one value of at least one parameter of the function with S-shape characteristics with at least one local tissue perfusion value (such as mean velocity, mean transit time, mean flow, perfusion volume) or attribute (such as the blood flow pattern, flow distribution variance or skewness).

Blood flow estimates through replenishment curve fitting in ultrasound contrast imaging

A method for coding pixels or voxels of a digital or digitalized two dimensional or three dimensional image includes the steps of: providing a digital image in which each pixel or voxel is defined by a variable in a grey scale image, or by HSV or RGB values in a color image; generating a vector univocally associated to the target pixel or voxel and having components generated as a function of the values of the pixels or voxels in a window that includes the target pixel or voxel and neighboring pixels or voxels. The function of the values of the target pixel or voxel and of the pixels or voxels in the window corresponds to the characteristic parameters of the numerical matrix representing the pixels or voxels of the window or of a transformation of the numerical matrix.
