Abstract: A data processing method, performed by a computer, for determining implant positions of two implant components relative to two bones, wherein each of the implant components is to be attached to one of the bones such that the implant components form a joint between the bones, and wherein an implant position is a relative position between the implant component and the corresponding bone, said method comprising the steps of: a) acquiring a set of target poses, wherein a target pose represents a relative position to be achieved between the two bones; b) calculating a set of virtual poses for a pair of virtual test implant positions, wherein the set of virtual poses comprises one virtual pose for each of the target poses and wherein a virtual pose represents a relative position between the two bones if the virtual test implant positions were applied as the implant positions; c) calculating a pose deviation value for each of the target poses, wherein a pose deviation value represents the difference between a target pose and the corresponding virtual pose; d) calculating an overall pose deviation value from all the individual pose deviation values; e) repeating steps b) to d) for different pairs of virtual test implant positions until the overall pose deviation value fulfils a minimisation criterion; and f) using the pair of virtual test implant positions for which the minimisation criterion is fulfilled as the implant positions.

Abstract translation: 一种由计算机执行的用于确定两个植入部件相对于两个骨头的植入位置的数据处理方法，其中每个植入部件将被附接到一个骨头，使得植入部件在骨骼之间形成关节， 并且其中植入位置是所述植入物部件和所述对应骨骼之间的相对位置，所述方法包括以下步骤：a）获取一组目标姿态，其中目标姿势代表在所述两个骨骼之间实现的相对位置; b）计算一对虚拟测试植入位置的一组虚拟姿态，其中所述虚拟姿势集合包括用于每个所述目标姿态的一个虚拟姿态，并且其中虚拟姿势表示所述两个骨骼之间的相对位置，如果所述虚拟测试 植入位置作为植入位置; c）计算每个目标姿态的姿态偏差值，其中姿态偏差值表示目标姿态与对应的虚拟姿势之间的差; d）从所有个体姿态偏差值计算总姿态偏差值; e）对不同的虚拟测试植入位置对重复步骤b）至d），直到总体姿态偏差值满足最小化标准; 以及f）使用满足最小化标准的一对虚拟测试植入位置作为植入位置。

Abstract: The disclosed invention encompasses an image-based approach of calibrating an ultrasound-probe, wherein at least two ultrasound-images which cross each other are acquired with a tracked ultrasound probe, and wherein the intersection areas of these images, which have been calculated on the basis of the tracked spatial position of the ultrasound probe are checked for similar image content. The grade of similarity gives an indication as to how well the ultrasound probe is calibrated.
