Patent number: 10373328Abstract: Systems and methods for predicting shape are provided. A system for predicting shape can include a database, a training analysis module, a subject analysis module, and a prediction module. The database can store two sets of training models characterized by first and second parameters, respectively (e.g., bone and cartilage), as well as a subject model characterized by the first parameter (e.g., a bone model). The relationships between these models can be determined by a training analysis module and a subject module. Based on these relationships, the prediction module can generate a predicted shape characterized by the second parameter (e.g., a predicted cartilage model corresponding to the bone model).Type: GrantFiled: July 5, 2018Date of Patent: August 6, 2019Assignee: Materialise N.V.Inventors: Jan Maes, Tom Cluckers, Joris Van Deun

Patent number: 10343389Abstract: The present invention is directed to an improved method for supporting an object made by means of stereo lithography or any other rapid prototype production method. The generation of the support begins by determining the region that requires support in each layer of the object and defines a number of support points in this region. In a next step, a support mesh is generated connected to the object using these support points. The present invention also discloses different techniques that reduce superfluous edges to further optimize the support mesh. Finally, a support is generated from this support mesh. The present invention may facilitate the generation of supports data by employing more automation and less user analysis.Type: GrantFiled: December 1, 2014Date of Patent: July 9, 2019Assignee: Materialise N.V.Inventors: Gerald Eggers, Kurt Renap

Patent number: 10231847Abstract: The implant fixation systems disclosed herein include an implant manufactured with, or coupled to, one or more implant fixation devices used to secure the implant to bone. Various implant fixation device embodiments have an engagement element with a concave engagement tip, a guiding element defining a planned trajectory along which the engagement element is configured to move, and an adjustment element configured to move the engagement element along the planned trajectory. Moving the engagement element along the planned trajectory causes the concave engagement tip to enter a bone in a first position and rotate within the bone to a second position. Continuing to move the engagement element along the planned trajectory may cause the concave engagement tip to undergo translational movement from the second position to a third position, thereby pulling the implant towards the bone and exerting compression forces on the bone.Type: GrantFiled: August 10, 2015Date of Patent: March 19, 2019Assignee: Materialise N.V.Inventors: Benjamin Geebelen, Nils Faber

Patent number: 9977993Abstract: Systems and methods are provided for constructing a statistical shape model from a set of training shapes. In one embodiment, two shapes in the training set can be parameterized to a common base domain. Correspondence between the shapes can be evaluated using shape-specific data, such as, for the case of anatomical shapes, anatomical curves and/or anatomical landmarks. In evaluating correspondence, the shape-specific data about the second shape can be mapped to the shape-specific data about the first shape, and the mapping can be optimized based at least in part on a deformation energy of the mapping.Type: GrantFiled: May 19, 2016Date of Patent: May 22, 2018Assignee: Materialise N.V.Inventor: Joris Van Deun
