The invention concerns an image processing device, including an input for receiving a time series of data sets representing comparable volume digital images, each data having a position component and an intensity component, pre-processing means ( 18 ) for modifying the data sets so as to obtain images updated in position and intensity, and comparative processing means ( 20 ) for examining sets of time series of image elements and to detect therein signs of variations. The processing means ( 20 ) include a modeling function ( 12 ) for adjusting a parametric model separately on some of the sets of time series of image elements, to obtain pairs of data (image element, time) and a function for statistical analysis ( 14 ) of said pairs of data to isolate the pairs of data representing a significant variation.
