BACKGROUND Although rabbits have often been used as an experimental model for the analysis of lung preservation, there are no reports of long-term survival after rabbit lung allotransplantation. The purpose of this study was to establish a lung allotransplantation model for the evaluation of acute lung rejection in the rabbit and to investigate the transplantation techniques in the rabbit. ME...

In this paper we propose a method for the objective assessment of burn scars. The quantitative measures developed in this research provide an objective way to calculate scar elasticity. The approach combines range data and the mechanics and motion dynamics of human tissues. Active contours are employed to locate regions of interest and to find displacements of feature points using automatically...
