An evaluation system for determination of cardiovascular function parameters is provided. The evaluation system includes a data reading module, an image generating module, a contour determination module, an active contour module, a geometric center axis computing module, a view angle selection module and a function evaluation module. After reading cardiovascular graphic files with the data reading module, the image generating module displays 2D images or a 3D image constructed from the 2D images. Then, active contours are generated by the contour determination module and the active contour module, so as for the geometric center axis computing module to calculate geometric center axes. The view angle selection module then rotates the 3D image according to the view angle data received and modifies the 2D image files accordingly to generate plural cross-section images of the 3D image. Finally, the function evaluation module calculates evaluation parameters according to the geometric center axes. Thus, evaluation parameters can be derived from cardiovascular ultrasound images for clinical diagnosis in the evaluation of cardiovascular functions.

A method for detecting vascular sclerosis is revealed. Firstly set a cuff on a human hand. Then inflate the cuff and later deflate the cuff. Next measure a pressure of the cuff and generate a pressure sensing signal. Process the pressure sensing signal to generate a processed signal and convert the processed signal. Then calculate a systolic pressure and a diastolic pressure according to the converted processed signal and also obtain a vasodilation constant. Thus a hardening of blood vessels is detected according to the vasodilation constant.
