A patient-specific knee joint computer model using MRI data and 'in vivo' compressive load from the optical forcePotočnik, Božidar ...Modelling of patient knee joint from the MRI data and simulating its kinematics is presented. A flexion of the femur with respect to the tibia from 0° to around 40° is simulated. The finite element ... knee model is driven by compressive load measured 'in vivo' during MRI process by using specially developed optical force measurement system. Predicted kinematics is evaluated against the high-quality model obtained by registration from experimentally gathered low-quality MRI at fixed flexions. Validation pointed out that the mean square error (MSE) for the Euler rotation angles are bellow 1.73°, while the MSE for Euler translation is smaller than 5.93 mm.Source: CIT : journal of computing and information technology. - ISSN 1330-1136 (Vol. 16, no. 3, 2008, str. 209-222)Type of material - article, component partPublish date - 2008Language - englishCOBISS.SI-ID - 12706326
