About
Ludwig Ritschl 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 motorized imaging platforms for orthopedic and musculoskeletal applications. His most influential contribution—a foundational characterization of a twin robotic X-ray system capable of both 2D radiographic and 3D CBCT imaging—has garnered 24 citations and established a technical framework that underpins much of his subsequent research. Building on this, Ritschl has made significant strides in optimizing scan trajectories, including tilted rotation axis geometries and application-specific orbits for challenging anatomies such as the weight-bearing spine and cervical vertebrae, addressing longstanding issues of scatter, noise, and geometric misalignment. His investigations into slot-scanning tomosynthesis, tin prefiltration, and dual-energy techniques reflect a consistent drive to improve image quality while minimizing radiation dose—a critical concern in clinical practice. More recently, his exploration of dual-energy CBCT for bone marrow edema detection points toward expanding diagnostic capabilities in orthopedic imaging. Collectively, Ritschl's portfolio, accumulating over 80 citations, demonstrates a coherent and impactful research trajectory at the intersection of medical physics, imaging system design, and clinical translation.
