    An application framework for rapid prototyping of clinically applicable software assistants
    (INFORMATIK 2006 – Informatik für Menschen, Band 1, 2006) Rexilius, Jan; Kuhnigk, Jan-Martin; Hahn, Horst K.; Peitgen, Heinz-Otto
    Computer assistance for clinical diagnosis support and treatment planning are continuously growing fields that have gained importance in several medical disciplines. Although a variety of algorithms are available today, only few are routinely applied for diagnosis support and treatment planning. We propose a hierarchical framework that allows for flexible and efficient development of clinically valuable software prototypes and for systematic evaluation of image processing methods in a research setting. A modular plug-in concept separates algorithmic and framework developments. Several basic components for data-, user-, and workflow-management provide a skeleton that can be customized by both application developer and user. Standardized interfaces allow the communication between both frame and application. Dedicated assistance is provided for an efficient radiological workflow integration. A flexible and simple handling of image processing and visualization algorithms within a modular programming interface is offered through an integration into a visual programming and rapid prototyping platform (MeVisLab). The capabilities of our framework are presented by means of exemplary prototypes, that are currently used in clinical practice.

    Benutzungsschnittstellen für den direkten Zugriff auf 3D-Planungsdaten im OPUser Interfaces for Direct Interaction with 3D Planning Data in the Operating Room
    (i-com: Vol. 8, No. 1, 2009) Ritter, Felix; Hansen, Christian; Wilkens, Kjen; Köhn, Alexander; Peitgen, Heinz-Otto
    Zur Unterstützung komplexer chirurgischer Eingriffe stehen seit einiger Zeit computergestützte Planungssysteme bereit. Für den direkten Zugriff im OP sind diese Systeme jedoch nur sehr eingeschränkt einsetzbar, da sie für die präoperative Planung entworfen wurden und die besonderen Bedingungen im Operationssaal nicht berücksichtigen. Die speziellen Anforderungen in Bezug auf kognitive Beanspruchung, Arbeitsfluss, Sterilität und Platz machen es dem Chirurg weitestgehend unmöglich, während der OP einen Computer mit den üblichen Eingabegeräten wie Tastatur und Maus zu bedienen. Dieser Artikel diskutiert zwei Konzepte zur intraoperativen Betrachtung von virtuellen Planungsmodellen für Operationen an der Leber. Die praktische Anwendbarkeit der Konzepte wird anhand einer Fallstudie diskutiert.

    Software-supported planning of liver interventions – experience of more than10 years
    (INFORMATIK 2006 – Informatik für Menschen, Band 1, 2006) Schenk, Andrea; Bourquain, Holger; Zidowitz, Stephan; Hindennach, Milo; Konrad, Olaf; Peitgen, Heinz-Otto
    Computer assistance for the planning of liver interventions was the main focus of the initial project at our institution. Starting with the idea to compute patient-individual liver territories for tumor resections, dedicated algorithms were developed and integrated into a first prototypical software-assistant. Over one decade, experiences together with several clinical partners led to a software-tool that has proven clinical relevance. Until now, more than 1600 liver interventions like tumor resections, ablations, and living donor liver transplantations were planned with the help of the software, which was FDA-approved in 2005. While the planning itself is offered worl-wide as a commercial service, the software is being extended continuously and builds the basis for subsequent ne applications and studies in different research projects.

    Towards a workflow oriented software assistance for the radiofrequency ablation
    (INFORMATIK 2006 – Informatik für Menschen, Band 1, 2006) Weihusen, Andreas; Ritter, Felix; Pereira, Philippe L.; Helmberger, Thomas; Hoffmann, Ralf-Thorsten; Peitgen, Heinz-Otto
    In recent years, radiofrequency ablation of liver tumors has become a serious alternative to surgical resection for unresectable colorectal metastases. The treatment success highly depends on an effective placement of the radiofrequency applicators into the tumor to get a sufficient coagulative necrosis. Therefore, several software tools have been developed for the support and planning of a good treatment strategy. The software solution proposed in this paper aims at the assistance of the radiologist at each stage of the ablation workflow, including the tasks of planning, intervention and treatment assessment.
