Intra-operative Imaging & Visualization

by Marco Feuerstein, Tobias Sielhorst, Joerg Traub, Wolfgang Wein & Prof. N. Navab

Typ: Praktikum
SWS: 6+0
Generelle Studienplaneinordnung: BS-INF WA ab 5, INF. prakt. WP ab 5

Introduction

This lab course focuses on the development of intra-operative image guidance systems. Teams of 3-6 members are built and each team is assigned to a specific problem and a surgical expert. Each team has to understand its specific problem domain. Classical stages of software engineering like requirement analysis and system design will be performed in prior to the implementation of an fully functional prototype. Other then getting the knowledge of medical imaging techniques, common computer vision problems, e.g. segmentation, registration and calibration, are taught.

The projects will be done mainly using C++. Introductory classes will be conducted, and the teams will be supervised continuously.

Projects / Teams

Team 1: Data Fusion

supervised by Wolfgang Wein, see the Lab Course page
The planning of radiation therapy procedures is mainly done based on a CT scan of the patient. Both for patient positioning and precise target planning, additional modalities like X-Ray or Ultrasound images can be used. Therefore it is necessary to find their right spatial alignment (Registration) within the CT data. This might be done based on interactive or automatic registration, with help of anatomical landmarks, external position encoding or other means.
Goal of this project is to develop a prototypical application for the fusion of the preoperative CT scan with other 2D images. The team has to build up a graphical user interface, registration algorithms, volume visualization and more. To a certain extent existing libraries can be used. The implementation of the software prototype will be done in C++, the platform and development environment will be decided on later.

Team 2: Orthopaedic & Trauma Surgery

supervised by Tobias Sielhorst
see the Lab Course page
DelivARy extends a monitor and model based birth simulator, developed by the "Institute of Automatic Control Engineering" (Department of Electrical Engineering and Information Technology, TUM) and the "Clinic for Orthopedics" (Klinikum Rechts der Isar, Muenchen) to an augmented reality system.

The purpose of the birth simulator is to assist teaching midwife students forceps deliveries.

The conventional birth simulator is composed of

  • an anatomically correct plastic model of the female pelvis major with a vaginal access,
  • a model baby head inside the pelvis
  • and dedicated simulation, visualization and sensor control software.

Team 3: Endoscopic Techniques

supervised by Marco Feuerstein and Joerg Traub
see the Lab Course page
In endoscopic surgery, the surgeon inserts the instruments through very small incision points. Thus, the view onto the region of interest is very limited. In order to provide enhanced visualization to the surgeon the endoscopic images need to be augmented by pre-operatively acquired data such as CT slices or rendered volumes and models of the instruments. To do so, the surgical instruments and the endoscopic camera will be tracked to dynamically update their poses (positions and orientations). A viewer will be implemented to display the pre-operative data and all models at the correct poses.

For the implementation we will use C++. Preliminary knowledge is of advantage, but not compulsory.
