3D Ultrasound Image Acquisition Using a Magneto-optic Hybrid Sensor for Laparoscopic Surgery
A 3D ultrasound system suitable for laparoscopic surgery using a novel configuration of a magneto-optic hybrid 3D sensor is reported. A miniature magnetic sensor with five degrees of freedom (5D) is combined with an optical sensor outside the body to perform 6D sensing of the flexible probe in the abdominal cavity. The accuracy of the system is evaluated in comparison with a conventional 3D ultrasound system.
