Development of accurate navigation system for otologic surgery

下列主要进展或已发表或已提交出版：我们开发了一种新的微创图像引导手术方法。我们开发了一种在图像引导手术中获取手术钻头位置日志的系统。该数据可用于制作虚拟术中CT.3。我们在上述方法的基础上改进了一种方法，以提高颞骨深部的配准精度。

The following major progresses were either published or submitted for publication.1. We developed a new minimally invasive method for image-guided surgery.2. We developed a system that acquires location log of surgical drill during the image-guided surgery. This data could be used to produce a virtual intraoperative CT.3. We developed a refined method of our method described above to improve registration accuracy in deep region in the temporal bone.
