Patent number: 10672124Abstract: A system for creating decision support material indicating damage to an anatomical joint of a patient. The system is configured to: i) receive a series of radiology images of at least a part of the anatomical joint; ii) obtain a three-dimensional image representation of the at least part of the anatomical joint; iii) identify tissue parts of the anatomical joint using image analysis; iv) determine damage to the anatomical joint by analyzing said image representation; v) mark damage to the anatomical joint in the obtained three-dimensional image representation; and vi) generate decision support material. The analysis comprises: detecting an irregular shape of a contour of a tissue part; and/or detecting that the intensity in an area within or adjacent to bone and/or cartilage parts differs from a predetermined value; and/or comparing at least one identified tissue part with a template representing a predefined damage pattern for an anatomical joint.Type: GrantFiled: May 4, 2018Date of Patent: June 2, 2020Assignee: Episurf IP-Management ABInventors: Richard Lilliestråle, Anders Karlsson, Jeanette Spångberg, Nina Bake
