Abstract
The use of computer-based image analysis belongs to the new methods of biocompatibility testing. When materials were implanted subcutaneously in animals the cells of the connective tissue capsule can give a good standard for the evaluation of biocompatibility. The application of image processing systems allows the automation of a great number of measurings and test-techniques. It is also possible to get quantitative information on cell-and haemocompatibility testing. With the help of the automatic microscopic image analysis the accuracy of morphometric methods increased and scientists time was saved.
