PreimAbstractMinimally invasive surgery has advanced rapidly in the last years because of theaccelerated convalescence of the patient. However, such interventions demand a lotof experience due to limited access to the field of operation. In particular, the trocarplacement and the orientation within the patient’s body are hampered. Throughthe invention of navigation hardware, the tracking of the surgical tools and cam eras became possible, which revolutionized intra operative image guided surgerygenerally. Nowadays, there are a variety of applications that allow the navigationand guidance of tools with high accuracy, ranging from neurosurgical interventionsto osseous applications. In the case of minimally invasive liver surgery, one pos sibility for intervention assistance is the fusion of laparoscopic video images andtomographic volumes at operation time in order to present orientational aids basedon navigation hardware.
