Magneto-Optic Tracking of a Flexible Laparoscopic Ultrasound Transducer

Magneto-Optic Tracking of a Flexible Laparoscopic Ultrasound Transducer

In abdominal surgery, a laparoscopic ultrasound transducer is commonly used to detect lesions such as metastases. The determination and visualization of position and orientation of its flexible tip in relation to the patient or other surgical instruments can be of much help to (novice) surgeons utilizing the transducer intraoperatively. This difficult subject has recently been paid attention to by the scientific community. Electromagnetic tracking systems can be applied to track the flexible tip. However, the magnetic field can be distorted by ferromagnetic material.

We present a new method based on optical tracking of the laparoscope and magneto-optic tracking of the transducer, which is able to automatically detect and correct field distortions. This is used for a smooth augmentation of the B-scan images of the transducer directly on the camera images in real time.
Navigated Bronchoscopy

Navigated Bronchoscopy

A common task during broncoscopy procedures is to biopsy peripheral lung tumors. The video bronchoscope is not capable to reach the peripheral lung nodes, but only the biopsy needle. Thus there is no video feedback, but only feedback of the current location of the biopsy tool by fluoroscopy imaging during the intervention. This exposes patient and surgical staff to additional radiation. Another drawback is that tumors can not be visualized on the fluoroscope images and they are only a projection, thus do not report the three dimensional position of the biopsy tool. Electromagnetic tracking is capable of tracking the tip of flexible instrument. A field generator with three orthogonal coils introduces current and thus generates a magnetic field. A sensor composed also of three orthogonal coils is capable to estimate its position and orientation with respect to a coordinate system defined by the field generator. Currently we investigate the combination of all available information for navigation and solutions to represent it in one unified user interface. This includes the measurements of the electromagnetic tracking system, the c-arm, techniques of virtual bronchoscopy, and other data. Furthermore, clinical evaluation is conducted. We define the clinical endpoint and show through studies that the procedure will benefit from the usage of the navigation system.
Laparoscope Augmentation for Minimally Invasive Liver Resection

Laparoscope Augmentation for Minimally Invasive Liver Resection

In recent years, an increasing number of liver tumor indications were treated by minimally invasive laparoscopic resection. Besides the restricted view, a major issue in laparoscopic liver resection is the precise localization of the vessels to be divided. To navigate the surgeon to these vessels, pre-operative imaging data can hardly be used due to intra-operative organ deformations caused by appliance of carbon dioxide pneumoperitoneum and respiratory motion.

Therefore, we propose to use an optically tracked mobile C-arm providing cone-beam computed tomography imaging capability intra-operatively. After patient positioning, port placement, and carbon dioxide insufflation, the liver vessels are contrasted and a 3D volume is reconstructed during patient exhalation. Without any further need for patient registration, the volume can be directly augmented on the live laparoscope video. This augmentation provides the surgeon with essential aid in the localization of veins, arteries, and bile ducts to be divided or sealed.

Current research focuses on the intra-operative use and tracking of mobile C-arms as well as laparoscopic ultrasound, augmented visualization on the laparoscope's view, and methods to synchronize respiratory motion.

  • Hiwi Position for Image Processing in Navigated Bronchoscopy (Hiwi)
    We are looking for people extending our possibilities in navigated bronchoscopy. In particular, we'd like to have implementations of several medical image processing algorithms (segmentation, skeletonization, quantitative analysis) as building blocks for researching further approaches. This project will involve developing in C++ using our medical augmented reality framework CAMPAR, probably using Insight Segmentation and Registration Toolkit (ITK) components and possibly prototyping algorithms in Matlab. You should have good programming skills in C++ and Matlab and preferably working knowledge of ITK. Based upon this work there will probably be opportunities for further projects in this area at CAMP, e.g. IDP or Bachelor/Master/Diploma thesis. If you are interested or if you have questions please contact Tobias Reichl.
  • Quantification of Deformation in Navigated Bronchoscopy (DA/MA/BA)
    In navigated bronchoscopy one particular challenge is the deformation of the lung during patient movement, breathing and coughing. By combining available data from CT/virtual bronchoscopy, the video stream from the bronchoscope and electromagnetic tracking, the deformation of the lung should be quantified. For the part of the lung which is reachable with bronchoscope, a patient-specific map of deformation due to respiratory motion should be generated. Methods for compensation of this respiration motion should be evaluated. Working knowledge of C++ required. Knowledge of OpenGL and Qt is of advantage. This project is going to be located at the IFL lab and will be done in close collaboration with the Pneumology department of the Kinikum rechts der Isar. Depending on progress of the project, clinical trials e.g. for compensation methods might be possible. If you have questions please contact Tobias Reichl.
  • If you have your own ideas for a project, just come by to talk about it.
