Abstract

The biomechanical complexity of knee articulation reflects in the extreme difficulty for non-invasively evaluating the possible pathological alterations. At present, only tomographic techniques are able to provide three-dimensional information of a joint. In this work, MR tomography has been taken into consideration. The kinematic analysis of the movement calls for the acquisition of images corresponding to the various phases of the movement itself. Ten series of images have been acquired, each series being considered as a volume by piling up the tomographic slices. Computation of the Optical Flow has been applied to quantify the displacement vectors between a volume and its successors versus time. This technique is under clinical evaluation by orthopaedicians to verify if it is possible to identify significative differences between the results obtained from healthy patients as compared to those obtained from patients affected by capsulo-ligamental pathology.
