Knife Tip Position Estimation Using Multiple Markers for Liver Surgery Support

Abstract

In recent years, the elderly population has been steadily increasing. In particular, the population is aging more rapidly in Japan than other developed countries. Surgical procedures for the elderly carry substantial risk, and there is an immediate need for measures to reduce this risk. We have been developing a support system for liver surgery by using IT technology. In this study, we focus on a high-accuracy measurement method for ascertaining the knife tip position with multiple markers during surgery.
