Abstract
A method and a device for use in conjunction with an imaging modality (202), for controlling the angular orientation of a needle-shaped object (212) while moving it along a path (214) from a given entry point to a given target point in a body during a percutaneous intervention. The device comprises a support unit (502, 602, 702, 802) for supporting a guiding unit (506, 706), which support unit provides a pair of parallel control planes (604, 606) which are at least partially detectable by the imaging modality. The guiding unit establishes a guiding axis (612, 818) substantially perpendicular to the pair of parallel control planes along which guiding axis the needle-shaped object is translatable. The angular orientation of an imaging plane (204) applied by the imaging modality determines a reference for the angular orientation of the pair of parallel control planes. By aligning the pair of parallel control planes with the imaging plane, the guiding axis is in correlation with the path from the entry point to the target point.
