The technique is based on canonical correlation analysis a statistical method which makes use of the spectral-spatial information characterizing X-ray diffraction data measured from bone samples with implanted tissues. The performance has been compared with a standard crystallographic technique in terms of accuracy and automation. The proposed approach is able to provide reliable tissue classification with a direct tissue visualization without requiring any user interaction. Copyright 2007 M. Ladisa et al.

INTRODUCTION One of the main goals of tissue engineering is the reconstruction of highly damaged bony segments. To this aim it is possible to exploit the patient s own cells which are isolated expanded in vitro loaded onto a bioceramic scaffold and finally reimplanted into the lesion site. Generally bone marrow stromal cells BMSC are adopted as described in 1 . In this respect it would be important to characterize the structure of the engineered bone and to evaluate whether the BMSC extracellular matrix deposition on a bioceramic scaffold repeats the morphogenesis of the natural bone development. In addition it is also interesting to look into the
