摘要： A system and method for preparing a virtual three-dimensional representation of a first portion of a bone. The method may comprise obtaining, from a first orientation with respect to the first portion of the bone, first image data of the first portion of the bone and obtaining, from a second, different orientation with respect to the first portion of the bone, second image data of the first portion of the bone. A three-dimensional (3D) virtual representation of the first portion of the bone may be generated. The 3D virtual representation of the first portion of the bone may be displayed. The displayed 3D virtual representation may have an orientation, determined using at least the difference between the first and second orientations from which the first and second image data were obtained.

摘要： An acetabular component alignment device for total hip arthroplasty comprises a calibration component allowing for aligning a main instrument axis (5) of the acetabular component depending on a set of two patient specific calibration parameters relating to rotational offsets of the acetabular component, whereas the device is constructed in such a way that calibration parameters may be chosen such that a second parameter of the set of calibration parameters is adjustable independently from a first parameter of the set of calibration parameters by rotating the acetabular component around the main instrument axis (5) of the acetabular component. A method for obtaining patient specific calibration parameters for alignment of an acetabular component in total hip arthroplasty, comprises the steps of determining patient specific morphology information relating to a geometry of the patient's pelvis; and processing the patient specific morphology information for obtaining a set of two patient specific calibration parameters relating to rotational offsets of the acetabular component. The calibration parameters are chosen such that a second parameter of the set of calibration parameters may be adjusted independently from a first parameter of the set of calibration parameters by rotating the acetabular component around a main instrument axis of the acetabular component.
