Method and device for correction motion in imaging during a medical intervention

A method for correcting a motion in an imaging during a medical intervention on a patient, comprising:

• inserting a medical instrument into a target area of the patient;
• recording a 3D tomographic image of the target area of the patient comprising the instrument;
• recording a 2D fluoroscopic image of the target area during the intervention;
• registering the 2D fluoroscopic image with the 3D tomographic image;
• identifying the instrument in the 2D fluoroscopic image and the 3D tomographic image based on the registration;
• computing a representation from the 3D tomographic image perspetively concurring with the 2D fluoroscopic image based on the identification;
• adjusting the registration by registering the 2D fluoroscopic image with the computed representation in a real time;
• and
• jointly displaying the 2D fluoroscopic image and the representation of the 3D tomographic image.

A device for correcting a motion in an imaging during a medical intervention on a patient, comprising:

• a C-arm x-ray device that generates a 3D tomographic image of a target area of the patient and a 2D fluoroscopic image of the target area during the medical intervention;
• an input interface that inputs the 3D tomographic image and the 2D fluoroscopic image;
• a first identification device that identifies a medical instrument for performing the intervention in the 3D tomographic image;
• a second identification device that automatically identifies the medical instrument in the 2D fluoroscopic image;
• a computing device that:
• registers the 2D fluoroscopic image with the 3D tomographic image,
• computes a representation from the 3D tomographic image perspetively concurring with the 2D fluoroscopic image, and
• adjusts the registration by registering the 2D fluoroscopic image with the computed representation;
• and
• a display device that displays the representation jointly with the 2D fluoroscopic image.
