About
S. Kappler is a medical imaging researcher whose work centers on advanced X-ray and cone-beam computed tomography (CBCT) systems, with a particular focus on robotic and twin-robotic X-ray platforms. Operating at the intersection of system optimization, image quality, and clinical application, Kappler has made meaningful contributions to how modern flexible imaging systems can be harnessed for orthopedic and spinal imaging challenges. Among Kappler's most recognized contributions is pioneering work on CBCT acquisition using tilted rotation axes, which leverages the trajectory flexibility of robotic X-ray systems to reduce scatter and noise — a paper that has garnered 18 citations since 2020. Additional impactful work spans trajectory optimization for weight-bearing spine imaging, misalignment compensation for ultra-high-resolution CBCT, and slot-scanning tomosynthesis for dose-efficient orthopedic radiography. Notably, Kappler has explored tin prefiltration strategies and dual-energy techniques for bone mineral density measurement and bone marrow edema detection, pointing toward quantitative, clinically actionable imaging. Collectively, Kappler's research addresses real-world clinical imaging constraints — scatter, dose, speed, and resolution — by exploiting the programmable geometry of robotic systems. This body of work provides a valuable foundation for researchers and clinicians seeking to advance orthopedic and musculoskeletal imaging beyond conventional fixed-geometry approaches.
