Dunlee has emphasized the crucial role of X-ray tubes in the effectiveness of advanced imaging technologies like photon-counting CT (PCCT) and ultra-high resolution CT (UHRCT). At a recent event during ECR 2026, Stefanie Krämer, a Dunlee manager, compared the situation to using a high-quality camera with a low-quality lens, highlighting that advancements in detector technologies haven’t always matched the improvements in tube technologies. Dunlee introduced its Xpert Bundle product line, featuring various focal spot sizes to optimize resolution in imaging across several medical specialties, such as cardiology, oncology, and neurology. The engineering challenges of maintaining small, stable focal spots under clinical conditions, especially due to heat management issues, were also discussed. Dunlee's new designs incorporate innovations like liquid metal bearings for improved performance and heat dissipation, essential for achieving high-speed gantry rotations that enhance image quality. As PCCT systems become more widely utilized, the significance of tube capabilities is increasingly becoming a focal point for radiologists and procurement teams.
