Dynamic measurement of parameters within a sequence of images

A method of dynamically measuring parameters within a series of images using image processing is disclosed. A sequence of ultrasound images is generated by means of an ultrasound system. A user determines at least one region of interest within a first image. Then, at least one parameter for each region of interest is evaluated, e.g. the number of pixels exceeding a pre-defined intensity are counted. A new region of interest within a sequential image is searched within a search area around the predefined region of interest which best matches the region of interest. This is done for all images of a sequence whereby the new region of interest which best matches the region of interest of the previous image is used as a region of interest for the following image.
