Abstract: A method and system for grading pistons with deposits is disclosed. In an embodiment, a piston with upon its outer surface deposits is three dimensionally scanned and compared to a reference model to detect the location and geometry of the deposits. The location and geometry of the deposits are recorded and used to grade the pistons. The piston is increased in temperature and thermally scanned. The deposits are identified based on the temperature differences measured with respect to the temperature of the outer surface of the piston. Deposit characteristics can be generated from the identified locations of deposits and the magnitude of temperature difference with respect to the outer surface. The deposit characteristics are recorded and used to grade the pistons.

Abstract: A method of determining wear of an artificial knee assembly (AKA) includes acquiring a first set of computed tomography (CT) data about the AKA in vivo. A first volumetric file is generated based on the first set of CT data. A first point cloud data set is generated based on the first volumetric AKA file. A first dimensional analysis of the AKA is performed using the first point cloud data set. A second volumetric file is generated based on a second set of acquired CT data before implantation or from a model. A second point cloud data set is generated based on the second volumetric AKA file. A second dimensional analysis is performed using the second point cloud data set. The first dimensional analysis is compared to the second dimensional analysis and a determination is made if they are different from each other.
