MiMed liver: A planning system for liver surgery

Abstract

In clinical routine of liver surgery there are a multitude of risks such as vessel injuries, blood loss, incomplete tumor resection, etc. In order to avoid these risks the surgeons perform a planning of a surgical intervention. A good graphical representation of the liver and its inner structures is of great importance for a good planning. In this work we introduce a new planning system for liver surgery, which is meant for computer tomography (CT) data analysis and graphical representation. The system is based on automatic and semiautomatic segmentation techniques as well as on a simple and intuitive user interface and was developed with the intention to help surgeons by planning an operation and increasing the efficiency in open liver surgery.

The effects of real-time image navigation in operative liver surgery

“…This component was integrated with the planning software MiMed Liver [5,6]. The main idea of the navigation concept is to mark target structures, which are focused on with the dissector, with cross-lines.…”

Development and Usability Testing of a User-Centered 3D Virtual Liver Surgery Planning System

“…The virtual realitybased virtual resection method was evaluated in terms of time efficiency and found that an average of 23.3 min per case was needed for surgery planning. Next, Shevchenko et al (2010) proposed a planning system for liver surgery by segmentation of the liver, vessels, and tumors using automatic and semi-automatic segmentation techniques, not including a virtual resection function.…”

Multiphase risk assessment of atypical liver resections

“…Recently, planning systems for liver resections were published [12,1,9,11,8], but they do not take multiple phases into account. However, there are tumors, which are only In this work, we present a system to assess surgical risk for atypical resections utilizing venous and arterial phases.…”
