Processing of CT images to solve biomechanical problems of locomotive organs
Nagy, Ivan ; Husták, Josef
This paper includes two methods of image segmentation, the first based on histogram separation and the second based on edge detector algorithm. These methods are compared on their advantages and disadvantages.
Ceramic head stress analysis for different loading types
Ochranová, M. ; Fuis, Vladimír
The paper aim is the problem of the influence of the different type of ceramic head of the total hip joint endoprosthesis loading to its stress.
Influence of the interaction of the production inaccuracies on the hip joint ceramic head reliability
Fuis, Vladimír
The aim of this paper is to refill the information about the influence of the production inaccuracies interaction.
Hip joint ceramic head reliability versus contact cone production inaccuracies
Fuis, Vladimír
The paper contains the results of the stress and reliability analyses of the total hip joint endoprosthesis ceramic head. The modelled system consists of the two parts: ceramic head and steel stem. The ordering of mentioned system is according the norm ISO 7206-5. The model production inaccuracies of the contact taper of the head and the stem are considered. The head stresses are obtained from the FEM solution and the head reliability is based on the Weibull weakest link theory.
