Claim:
1. An evaluation system for determination of cardiovascular function parameters, to be implemented in a computer hardware system, the evaluation system comprising: a data reading module for reading at least an graphic file, each said graphic file comprising a plurality of two-dimensional (2D) image files which are related to one another and are successively created at a plurality of time points in a time sequence; an image generating module for displaying the 2D image files as a plurality of 2D images and a 3D image constructed from the 2D images; a contour determination module for receiving point selection information generated by a user by selecting points in any said 2D image corresponding to an initial said time point, and for determining an initial contour in each said 2D image corresponding to the initial time point according to the point selection information; an active contour module for reading the initial contours and determining an active contour in each said 2D image; a geometric center axis computing module for reading the active contours and computing a geometric center axis corresponding to each said time point; a view angle selection module, which receives a view angle data, rotates the 3D image according to the view angle data and modify the 2D image files read by the data reading module accordingly to generate plural cross-section images of the 3D image relative to the view angle data received; and a function evaluation module for successively computing a difference between the active contours corresponding to each said time point in the time sequence and a corresponding said geometric center axis, and for generating an evaluation parameter accordingly.
