Carbon Fiber in Ablation Applicators: Structure, Function, and Clinical Applications

Advances in image-guided tumor ablation have increased the demand for applicator materials that combine mechanical strength, imaging compatibility, and procedural safety. Carbon fiber has emerged as an important structural material in several ablation platforms, particularly those designed for magnetic resonance imaging (MRI)-guided interventions and microwave-based therapies. Unlike metallic components that actively deliver energy, carbon fiber typically serves as the shaft, sheath, or supporting structure of the applicator. Its low imaging artifact, favorable stiffness-to-weight ratio, and resistance to unwanted electromagnetic interactions make it particularly attractive in modern ablation systems. This review summarizes the role of carbon fiber across various ablation modalities, discusses its advantages and limitations, and highlights representative commercial applications.
