Targeting method, targeting device, computer readable medium and program element

A targeting device for targeting a first object from an entry point to a target point, the targeting device comprising:

• a selecting unit which selects a two-dimensional image of the object under examination depicting the entry point and the target point;
• a determining unit which determines a planned path from the entry point to the target point, wherein the planned path has a first direction;
• a recording unit which records data representing a fluoroscopic image of the object under examination, wherein the fluoroscopic image is recorded under a second direction so that a normal of the image coincides with the first direction;
• wherein the determining unit determines whether the object is on the determined planned path based on a shape of a projection of the object in the fluoroscopic image.

A non-transitory-computer readable medium in which a program for targeting a first object from an entry point to a target point is stored, which program, when executed by a processor, controls the processor to perform a method comprising:

• selecting a two-dimensional image of the object under examination depicting the entry point and the target point;
• determining a planned path from the entry point to the target point, wherein the planned path has a first direction;
• recording data representing a fluoroscopic image of the object under examination, wherein the fluoroscopic image is recorded under a second direction so that a normal of the second direction of the image coincide with the first direction;
• determining whether the object is on the determined planned path based on a shape and/or position of a projection of the object in the fluoroscopic image.

A method for targeting a first object from an entry point to a target point, the method comprising:

• selecting a two-dimensional image of the object under examination depicting the entry point and the target point, the two-dimensional image selected as a slice of a three-dimensional image of the object under examination acquired by a first imaging modality;
• determining a planned path from the entry point to the target point, wherein the planned path has a first direction;
• recording data representing a fluoroscopic image of the object under examination utilizing a second imaging modality, wherein the fluoroscopic image is recorded under a second direction so that a normal of the second direction of the image coincide with the first direction;
• determining whether the object is on the determined planned path based on a shape and/or position of a projection of the object in the fluoroscopic image.
