Correct positioning of the tibial component in total knee arthroplasty (TKA) must take into account both an optimal bone coverage (defined by a maximal cortical bearing with posteromedial and anterolateral support) and satisfactory patellofemoral tracking. Consequently, a compromise position must be found by the surgeon during the operation to(More)
This study proposes a detailed FEM of a human volunteer's neck and proceeds to an original model validation against experimental data recorded with this human volunteer. In order to evaluate the new model against existing data a successful temporal validation of the model was obtained under frontal, lateral, oblique and rear impact. New validation(More)

The last years have seen an explosion of systems in image analysis. It is hard for the pathologist or the cytologist to make the right choice of equipment. All machines are stupid, and the only valuable thing is the human work put into it. So make your benefit of the work other people have done for you. Chose a method largely used on many systems and which(More)
This paper describes the application of a television-based system (LEYTAS) in machine analysis of cervical specimens. LEYTAS basically consists of a Leitz microscope, the texture analysis system (TAS, Leitz), a TV camera, a 4-bit grey value memory and a minicomputer (PDP 11/23). A series of 1176 Feulgen stained cervical smears has been analysed in an(More)

The Leyden Television Analysis System (LEYTAS) is applied to the automated analysis of five positive specimens (2 cases of severe dysplasia, 2 cases of carcinoma in situ and 1 case of invasive carcinoma) and five negative specimens (4 cases of inflammation and 1 normal specimen). Two detection criteria based on size and contrast (so called 'top hat'(More)
In order to develop an objective grading system for nuclear atypia in breast cancer, an image analysis technique has been applied for the automated recognition of enlarged and hyperchromatic nuclei in cytology specimens. The image segmentation algorithm, based on the 'top hat' image transformation developed in mathematical morphology, is implemented on the(More)
Three-dimensional (3-D) images of osteocyte lacunae were examined on a confocal microscope. Both geostatistical and morphological processing techniques were used to improve and to analyse them. By a geostastical approach, this study aims at improving 3-D confocal images before any further image processing. Optimized linear filters, which take account of the(More)
