Successful treatment of a T4 lung tumor with vertebral body invasion using fiducial markers in the thoracic spine for image-guided radiation therapy: A case report

Journal of Medical Case Reports, 2011
Introduction Paravertebral and paraspinal tumors pose a significant challenge in radiation therapy because of the radiation sensitivity of the spinal cord and the need for maximum treatment accuracy. Implantation of fiducial markers into vertebral bodies

Editorial Commentary: The Femoral Impingement Index: Can Composite Morphology Better Capture Femoroacetabular Impingement Syndrome?

Arthroscopy, EarlyView.
Abstract Hip arthroscopy has undergone remarkable evolution over the past 2 decades. Improvements in patient selection, advanced imaging, labral preservation, capsular management, and osseous correction of femoroacetabular impingement syndrome have translated into consistently favorable outcomes for appropriately selected patients.

Robust Tracking Through the Design of High Quality Fiducial Markers: An Optimization Tool for ARToolKit

IEEE Access, 2018
Fiducial markers are images or landmarks placed in real environment, typically used for pose estimation and camera tracking. Reliable fiducials are strongly desired for many augmented reality (AR) applications, but currently there is no systematic method

Augmentation of Arthroscopic Rotator Cuff Repair Using Enthesis Interpositional Allograft and Minced Autologous Subacromial Bursa

Arthroscopy Techniques, EarlyView.
Abstract Multiple strategies for rotator cuff augmentation have been developed to promote tendon healing and decrease retear rates. Previously published techniques and clinical studies have primarily emphasized biologic adjuncts intended to alter the local healing environment at the repair site or structural reinforcement with grafts.
