To improve the diagnostic yield, a precise navigation to the target region using a electromagnetic position and orientation (pose) measurement device (electromagnetic tracker) is used. An electromagnetic tracker generates an electromagnetic field and a coil sensor measures its position and orientation by the induction of current in the cois. An interface that provides the real-time pose of the sensor is provided.
The navigation system that has to be implemented within this SEP has to visualize three orthogonal views of CT data and show a crosshair at the measured position of electromagnetic device in all three views. A point based registration method will be provided in order to register the coordinate system of the tracker with the patient's data.
The implementation will be in C++ (VS Compiler) using OpenGL. An interface to access the real-time data of the electromagnetic tracking device will be provided, as well as a library to read the medical imaging data(DICOM) as recieved from the CT scanner.
The figure shows a mock-up of the intervention with the electorimagnetic tracking device on the left and a mock-up for the user interface on the right.

Title: | Navigated Flexible Procedures (Bronchoscopy) |
Abstract: | Bronchoscopy minimally invasive access to peripheral lung locations. The goal is to implement an application that visualizes within imaging data of computed tomography images the actual position of a electrimagnetic sensor. Therefore, a graphical user interface that visualizes three orthogonal sliceviews as well as a crosshair, that indicates the current position of the sensor. For tracking the Aurora system from Northern Digital will be used. |
