Safety and Efficacy of Ultrasound-Guided Fiducial Marker Implantation for CyberKnife Radiation Therapy
OBJECTIVE To evaluate the safety and technical success rate of an ultrasound-guided fiducial marker implantation in preparation for CyberKnife radiation therapy. MATERIALS AND METHODS We retrospectively reviewed 270 percutaneous ultrasound-guided fiducial marker implantations in 77 patients, which were performed from June 2008 through March 2011. Of 270 implantations, 104 were implanted in me...
متن کاملMulti-Ring Fiducial Systems for Scalable Fiducial-Tracking Augmented Reality
In augmented reality (AR), a user can see a virtual world as well as the real world. To avoid registration problems between the virtual world and the real world, the user’s viewing pose in both worlds should be kept the same. Fiducial-tracking AR is an attractive approach to the registration problem. However, most of the developed fiducialtracking AR systems have restricted workspaces. To provi...
متن کاملFiducial Marker Detection Using FPGAs
This work presents an approach for computing camera pose from images of fiducial markers. The processing is shared between an FPGA and a PC: the FPGA converts grayscale camera images into binary format and transfers them to the PC; and the PC detects fiducial markers in the received binary camera images and computes the position and orientation of the camera. The approach is evaluated in terms ...
متن کاملFiducial Marker Navigation for Mobile Robots
Regarding mobile robots, navigation using fiducial markers has already been achieved and obstacle avoidance using search algorithms is common. However, the combination of these two ideas is relatively uncommon, and therefore, is the focus of this study. Owing to the mobility of these robots, good performance of the system is of utmost importance. Furthermore, since odometers on mobile robots ar...
متن کاملTreatment precision of image-guided liver SBRT using implanted fiducial markers depends on marker-tumour distance.
The purpose of this study is to assess the accuracy of day-to-day predictions of liver tumour position using implanted gold markers as surrogates and to compare the method with alternative set-up strategies, i.e. no correction, vertebrae and 3D diaphragm-based set-up. Twenty patients undergoing stereotactic body radiation therapy (SBRT) with abdominal compression for primary or metastatic liver...
