Currently, there are completely virtual training simulators as well as 3D printed vessel phantoms available to train neuroradiology interventions. With this work, we aim to combine both approaches by a camera-based guide wire tracking for the first time. To achieve this, the camera has to be calibrated to the mask of the 3D printed vessel phantom. Then, the guide wire is segmented in the camera image, its 3D position is estimated, and then it is projected into a virtual projection of a whole-body CT scan. A resulting example of our approach is shown, and further necessary future work is discussed.

摘要

Currently, there are completely virtual training simulators as well as 3D printed vessel phantoms available to train neuroradiology interventions. With this work, we aim to combine both approaches by a camera-based guide wire tracking for the first time. To achieve this, the camera has to be calibrated to the mask of the 3D printed vessel phantom. Then, the guide wire is segmented in the camera image, its 3D position is estimated, and then it is projected into a virtual projection of a whole-body CT scan. A resulting example of our approach is shown, and further necessary future work is discussed.
