ROTATIONAL POSITION DETERMINATION |
| 摘要 |
A method and a device is provided for determining a rotational position of a first feature of a first bone section relative to a second feature of a second bone section, the method comprises the steps of determining a longitudinal axis of a bone and determining a plane extending perpendicular to the longitudinal axis of the bone, determining a first projected vector representing a first direction defined by a feature of the first bone section, determining a second projected vector representing a second direction defined by a feature of the second bone section, and determining an angle between the first projected vector and the second projected vector. |

1. A method for determining a rotational position of a first feature of a first bone section relative to a second feature of a second bone section, the method comprising the steps of:
determining a longitudinal axis (X) of a bone and determining a plane (P) extending perpendicular to the longitudinal axis of the bone; determining a first projected vector (V1p) in the plane (P), based on a first direction defined by a feature of the first bone section; determining a second projected vector (V2p) in the plane (P), based on a second direction defined by a feature of the second bone section; determining an angle (A) between the first projected vector (V1p) and the second projected vector (V2p). |
