    Implementation of Direct Optimization Techniques for Deformable Image Registration

    Multimodal Consultation System for Patient Education in Plastic Surgery
    supervised by Christoph Bichlmeier and Nassir Navab
    In the medical field of breast reconstruction, different methods for patient self-education , quality management and approaches to predict real deformations of breasts already exist, however for the preoperative patient-surgeon discussion, appropriate visualization tools are missing. The possibilities for a surgeon to explain the limitations, risks and opportunities of different procedures of breast reconstruction are very limited. Nowadays the surgeon describes all critical issues using 2D illustrations, patient-based image material, 3D animations and videos. The present diploma thesis presents the initial steps of a long term project for improved patient education integrating an augmented reality system into the clinical workflow of breast reconstruction in plastic surgery. Based on feedback from our medical project partner Dr. med. Maximilian Eder (Klinikum Rechts der Isar), four other plastic surgeons and a commonly used patient education guideline provided by the company proCompliance, an augmented reality framework has been developed, to support the patient education. The motivation of this project is to enhance the patient’s knowledge of treatment options, to reduce decisional conflict, and stimulate patients to be more active in decision making without increasing their anxiety. The motivations are based on empirical research which demonstrates that many patients want to actively participate in the discussion. Furthermore the diploma thesis fits perfectly to the increasingly advocated ideal model of treatment decision-making in the medical talks: the shared decision-making. Main aims of the present project are the development of a realistic physical model for soft tissue and the application of this model to a 3D mesh gained from a 3D scanner in order to simulate the reconstructed breast. In addition, methods are proposed for a smooth image composition of the 3D mesh with the real patient. The movement of the patient by wearing a infrared marker set to be tracked by an ART system 2, influences the real-time deformation of the breast, which is simulated by a Mass-Spring System realized on the GPU. The whole augmented reality visualization is embedded into a framework, which also gives guidance to the surgeon through the shared decision-making process. The developed system is capable of integrating all aspects of any treatment option like risks during the patient-surgeon discussion and might thus protect the liability of a surgeon. I believe that the proposed information system for patient education supports the patient in decision making and helps the surgeon to easily explain details of the surgery and thus should improve the patient-surgeon relationship. It follows the ideal model of integrating the patient as well as the surgeon in a balanced way in the medical talks. Offering the patient as much responsibility as she wants and the surgeon an opportunity to go beyond a role of transferring information to also participate in, but not dominate, the decisionmaking process. The project is supported by KKF funding. Future proposals are planned to finally build a prototype for augmented reality based patient education. Semiautomatic segmentation of tumors in Positron Emission Tomography
    supervised by Ralph Bundschuh and Prof. Dr. Nassir Navab
    Ziel der Arbeit ist die semiautomatische Tumorsegmentierung in Positronen Emissions Tomographie (PET) Daten. Der Basis-Teil des Projektes besteht aus der Implementierung von bereits ausgesuchten Segmentierungsalgorithmen, dem Auffinden weiterer Algorithmen (Literatur- Recherche) für die spezifische Problemstellung, der Erweiterung zur Analyse von dynamischen (4D) PET Daten.

Research Projects

Augmented Reality Supported Patient Education and Consultation

Augmented Reality Supported Patient Education and Consultation

The project Augmented Reality Supported Patient Education and Consultation (Augmented Reality unterstützte Operationsaufklärung) aims at developing Augmented Reality (AR) supported communication tools for patient education. The development of the targeted systems involves disciplines reaching from image registration, human computer interaction and in-situ visualization to instructional design and perceptual psychology. As a primary clinical application, we determined breast reconstruction in plastic surgery.
MeTaTop A Multi Sensory Table Top System for Medical Procedures

MeTaTop A Multi Sensory Table Top System for Medical Procedures

A tabletop system in medical environments can be used for interactive and collaborative analysis of patient data but also as a multimedia user interface within sterile space. For preoperative planning physicians in charge with a particular patient meet to discuss the medical case and plan further steps for therapy. For this reason, they could collaboratively view and browse through all kind of available medical imaging data with the tabletop system. Alternatively such a system could be a central interaction device for all kind of equippment within the OR requiring user input, however, can not be operated by the sterile surgeon. We believe that the projection of all kind of user and information interfaces on a sterile glass plane would facilitate the clinical workflow.
This project is strongly related to the Tangible Interaction Surface for Collaboration between Humans project.
3D user interfaces for medical interventions

3D user interfaces for medical interventions

This work group aims at practical user interfaces for 3D imaging data in surgery and medical interventions. The usual monitor based visualization and mouse based interaction with 3D data will not present acceptable solutions. Here we study the use of head mounted displays and advanced interaction techniques as alternative solutions. Different issues such as depth perception in augmented reality environment and optimal data representation for a smooth and efficient integration into the surgical workflow are the focus of our research activities. Furthermore appropriate ways of interaction within the surgical environment are investigated.
