Abstract:
1. A method for computer-assisted evaluation of medical images, comprising: providing a computer with multiple data sets, each representing a respective medical image, each of said data sets comprising data representing a time-dependent variable in the respective medical images, said variable changing over time in the respective medical images with respect to a time origin that is common to the respective medical images, and at least two of said data sets being respectively obtained at different points in time with respect to said time origin; in said computer, automatically determining a measurement value of said time-dependent variable in a first of said at least two data sets for a first point in time at which said first of said at least two data sets was obtained; in said computer, automatically determining a measured value of said time-dependent variable in a second of said at least two data sets for a second point in time at which said second of said at least two data sets was obtained, said second point in time being after said first point in time; in said computer, automatically extrapolating an estimated value of said time-dependent variable in said first of said at least two of said data sets from the second measurement of the time dependent variable; and a calculated rate of change of the variable with respect to time in the second data set over a time duration between said first time and said second time, and identifying a difference between said measured value of said time-dependent variable in said first of said at least two of said data sets and said estimated value; and in said computer, generating a visual presentation, at a display screen in communication with said computer, of at least said second of said at least two data sets, with intensity values therein scaled dependent on said difference.
