In a medical imaging system the flexibility and power of measurement tools is improved by making the measurements objects themselves, whereby flexible interaction is provided. The measurement objects (52) are aware of their position relative to other graphical objects (50, 51), in the image. A user of a medical imaging system is thus enabled to easily perform desired measurements and to display the results thereof in a reliable and flexible manner. A method, an apparatus and a computer-readable medium are provided for processing cursored user interaction with a spatially displayed medical image for producing graphics related measurement data on the medical image. The medical image comprises at least one graphics object and dynamic measurement objects are attached to said graphics object, wherein the measurement object may be moved, removed or transferred to other graphic objects on the medical image at any time.
