Method for determining at least one applicable path of movement for an object in tissue

A non-transitory computer-readable medium comprising instructions for determining an applicable path of a movement of an object in a tissue based on intensity data obtained by a 3D imaging technique, the applicable path of movement connecting a starting postion of the object with a defined target location, which, when executed by a processor, configured the processor to perform acts of:

• defining the defined target location of a reference point of the object and choosing at least one possible starting postion of the reference point of the object;
• determining a candidate path of movement between each position of the at least one possible starting position and the defined target location;
• directly after the determining act, evaluating the candidate path of movement as being the applicable path depending on information about local intensity extrema and/or intensity variation resulting from the intensity data along each candidate path of movement, wherein the evaluating act is performed on an unsegmented image of the tissue and forms an output including the applicable path;and
• causing a rendering device to render the output on the rendering device.
