Abstract :
The work described presents a procedure aimed at automatically extracting the medulla duct outlines from a human femur radiographic image. The outlines are retrieved by referring to a suitable geometric model of the generic femoral cross section; the projection function derived from such a model is fitted on the grey level values corresponding to the rows of the digitised radiographic image by means of a least squares algorithm. The resulting outlines are used in a software system performing hip prosthesis preoperational planning.
