NeedlePlacement, AR view Navigated RF Ablation

Currently, RF ablation needles are used to treat tumors in every part of the body. In order to place the tip of the needle in the center of the lesion, US imaging is commonly used for guidance. In this case, the surgeon tries to visualize the tumor and the needle in the same US image. The needle however is not visible in the US image before insertion, making it difficult to imagine the tumor location relative to the needle tip and orientation. Additionally, the surgeon needs to precisely handle the US transducer and the needle at the same time.
The navigation system developed for this purpose as part of the CAMPAR framework helps to simplify the RF needle placement by dividing it into two simple consecutive tasks: lesion finding and needle placement. This way, the surgeon does not have to simultaneously hold the US probe and RF needle. Additionally, the needle can always be visualized relatively to the US plane.
