Abstract

Augmented Reality technology can be used in minimally invasive surgery to increase the physician's view by showing information gathered from patient medical images. The developed AR system can improve the performances of a surgeon involved in a minimally invasive surgery procedure and provide visual information, located in the correct position of the patient's body, not visible by means of normal senses. The virtual environment is built using the real patient's CT images. The developed application is based on the AR Toolkit and it is possible to visualize all the organs of the abdominal area or, using specific markers, only some of them. The system can be used in pre-operative planning of a laparoscopic surgical procedure in order to find both the right points to introduce the surgical instruments and the best path to reach the organ concerned in the surgical operation.
