Abstract
This paper describes investigations using the Particle induced M-ray E mission method (PIXE) to evaluate the concentration of Ca together wit h that of other elements (S, C1, and K) across the articular cartilage of domestic pigs in order to verify a putative influence of calcium o n the structural changes in early arthrotic stage, derived from NMR mi croscopic imaging. The measurements were carried out with focused ion beams of a lateral resolution down to 20 mu m. The main matrix compone nts (C, N, O) were evaluated from proton backscattering spectra.
