Laparoscopic surgery is a challenging surgical operation because inside information about the target organ cannot be fully understood from the laparoscopic image. In this study, a fusion technique of surface information of a laparoscope and inside blood vessel information of ultrasound is proposed for guidance during laparoscopic surgery. The proposed technique can display the blood vessel depth inside of the target organ by projecting the ultrasonic image over a laparoscopic image. The registration of the laparoscopic and ultrasonic images is performed by registering the surface of the target organ, which is found in the ultrasonic volumetric data and stereoscopic images acquired by the stereo laparoscope. The performance of the proposed technique was evaluated experimentally using a tissue-mimicking phantom. The total computation time was 8.61 s on a personal computer (Xeon processor, 3 GHz CPU). The location of the blood vessel including depth information permits the visualization of risky areas during laparoscopic surgery.
