Abstract: A sensor means is employed to sense a distance to the surface of a subject to be examined, so that a range image may be acquired. Intensity information may be acquired alongside the distance information. The distance information and intensity information may be evaluated to track the pose of the sensor means relative to the surface of the subject to be examined, so that anatomical data related to said subject may be displayed as seen from the position and/or orientation of the sensor means or display means. By moving the sensor means or display means along the surface of the subject to be examined, such as a patient in a hospital environment, the user hence gets the impression of being able to look directly into the human body.

Abstract: An embodiment is directed to a method and a system for assisting the targeting of a target with an elongate instrument, wherein the instrument is to be inserted into a living object's body part along a predetermined trajectory extending between an entry point of said instrument into said body part and a target point associated with said target. The method comprises an instrument directing assisting step for generating and displaying an image allowing a user to assess to which extend the longitudinal axis of the instrument is aligned with the vector connecting the target point and the tip portion of said instrument. Also, the method comprises an instrument guiding assisting step of generating and displaying an image allowing a user to assess to which extent the instrument motion during insertion thereof coincides with the predetermined trajectory.
