The present invention relates to a method for determining the spatial position of objects, in particular medical objects. First position data is acquired that describes a spatial position of an object in a first coordinate system. First transformation data is acquired that transforms the object's position from the first coordinate system to a second coordinate system. Based on the foregoing data, second position data is acquired that specifies the spatial position of the object in the second coordinate system. Second transformation data is acquired that transforms the object's position from the second coordinate system to an inertial coordinate system. Based on the second position data and the second transformation data, inertial position data is determined that specifies a position of the object in the inertial coordinate system.

The invention relates to a tracking reference, comprising: a reference array () featuring a positionally fixed arrangement of at least two tracking markers (); and an interface (A) for detachably coupling the reference array () to a base member (), wherein the interface (A) comprises at least one supporting surface () for contacting the base member (), wherein the interface (A) comprises magnetic means () which generate a force at the reference array, wherein the force (F) is directed away from the supporting surface ().

Detachable tracking reference array

The present invention relates to a computer-implemented medical method, a computer program and a system for determining a reconstructed image augmentation of a field of view provided by an augmented reality device (), wherein an image location and/or at least one image orientation of at least one two-dimensional reconstructed image () within the field view depends on the spatial position of at least one object ().

A computer-implemented medical method of determining the position of an anatomical region of interest of a patient's body is provided. The method includes acquiring finger model data, acquiring finger position data based on the finger model data and based on imaging the at least one finger, acquiring planning image data that describes a planning external surface of the anatomical region of interest, and determining anatomical region position data based on the finger position data and the planning image data, wherein the finger model data describes a user-specific model of the pose which is acquired by imaging the at least one finger when it attains the pose.

A data processing method for determining a range of motion of an artificial knee joint which connects a femur and a tibia via a medial ligament and a lateral ligament, wherein at least the femur comprises an implant which forms a medial condyle and a lateral condyle, the method comprising the steps of: acquiring the maximum lengths of the lateral ligament and the medial ligament for a particular flexion angle of the knee joint; calculating a first virtual position between the femur and the tibia in which the lateral condyle of the femoral implant touches the tibia and the medial ligament is stretched to its maximum length; calculating a maximum valgus angle of the range of motion from the first virtual position; calculating a second virtual position between the femur and the tibia in which the medial condyle of the femoral implant touches the tibia and the lateral ligament is stretched to its maximum length; and calculating a maximum varus angle of the range of motion from the second virtual position.

A medical upright positioning device includes a planar structure having a foot positioning device. At least one outer edge of the planar structure comprises an abutting or engaging device arranged in a predefined positional relationship to the foot positioning device, wherein the abutting or engaging device is operative to position the planar structure in at least one predefined orientation relative to a reference direction.
