Method and device for aligning a needle

A device for controlling an angular orientation of a needle-shaped object while attempting to move said object along a path from a given entry point to a given target point in a body during a percutaneous intervention, said device comprising:

• a display;
• an imaging processor;
• and
• a support unit for supporting a guiding unit, which support unit provides a pair of parallel control planes through which the guiding unit establishes a guiding axis along which a needle-shaped object is translatable, and wherein the guiding axis is substantially perpendicular to said pair of parallel control planes, which are at least partially detectable by the imaging modality,
• said imaging processor being configured for providing:
• via said display and in a viewing direction perpendicular to said path, a side view of the support unit;
• and,
• via said display and in said direction as the translating occurs, a depiction of a representation of an angular deviation of said pair of parallel control planes from said direction to enable corrective alignment of said pair of parallel control planes to said direction.
