Abstract

The present invention relates to a device for determining a target position (14) in a body (5) in relation to a treatment apparatus (12) in at least three dimensions. The device comprises a target device (20) arranged to be positioned at the target position (14) in the body (5), and the target device (20) is configured to be arranged at an initial position (13) in relation to the treatment apparatus (12). Furthermore, the target device (20) comprises a inertial motion sensor (21) arranged to determine a relative motion of the target device (20) from the initial position (13) to the target position (14), and is configured to determine the target position (14) in relation to the treatment apparatus (12) based on the initial position (13) and the determined relative motion of the target device (20).
