title: A concept for overlaid-type surgical navigation system with organ modification functions using non-contact type surface measurement.
abstract: Surgical navigation systems are clinically applied in cerebral and otological surgeries but they are only used in parts with minimum surgical transformation in regions in which the organs largely transform, such as in the abdomen. Therefore, we here propose a concept of a surgical navigation system that could be used in the regions such as liver, which largely transforms itself during surgery. We consider a method that measures the changes in the organ surface configuration during surgery and estimates the changes in the tumor and blood vessel structure following the transformation of the organ surface. We also report on the necessary disposition of each process of this method, especially on the basic examination of the organ transformation.
