Evaluation system for determination of cardiovascular function parameters using ultrasound images

An evaluation system for determination of cardiovascular function parameters using ultrasound images, to be implemented in a computer hardware system, the evaluation system comprising:

• a data reading module for reading at least an ultrasonographic file, each said ultrasonographic 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;
• a 2D image generating module for displaying the 2D image files as a plurality of 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;
• 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.
