Case Study: Carbon fiber Medical Imaging Equipment
Customer Requirements
When equipment structure becomes the bottleneck of image quality
Minimize X-ray Artifacts
The rotating gantry must be extremely stable and highly "transparent" to X-rays. Traditional materials or improper composites create image artifacts that interfere with diagnostic accuracy.
Lightweight & High-Speed Rotation
To achieve sub-second rotation speeds, reducing the weight of rotating components is critical to decrease drive load, lower energy consumption, and suppress centrifugal deformation.
Dimensional & Thermal Stability
Equipment generates heat during prolonged scanning. Materials must have extremely low thermal expansion coefficients to maintain nanometer-level positional stability between sensors and X-ray sources/detectors.
Biocompatibility & Cleanroom Compliance
All materials must meet stringent biocompatibility standards (e.g., ISO 10993) and be suitable for cleanroom manufacturing with no outgassing or leaching.
Project Challenges
"Zero-defect" challenges in medical-grade carbon fiber applications
"Radiation-Neutral" Material Engineering
The resin matrix, fiber type, and layup of carbon fiber all affect X-ray absorption and scattering. The difficulty lies in designing a composite material whose absorption characteristics match human tissue as closely as possible, eliminating "hardware artifacts" at the physical level.
Micron-Level Precision & Long-Term Stability
Dynamic deformation of giant rotating rings (over 1m diameter) at high speeds (e.g., 0.25 sec/rotation) must be controlled at the micron level. This requires materials with not only high static stiffness but also excellent creep and fatigue resistance, ensuring precision doesn't degrade over the device's 10-year lifecycle.
Medical Certification & Process Consistency
From raw materials (fibers, resins) to final components, the entire process must meet stringent medical device certifications (e.g., FDA QSR, ISO 13485). The greatest challenge is achieving "medical-grade" process stability, ensuring every product and production batch has completely consistent and traceable mechanical and imaging performance.

Dr. Sarah Johnson
Senior Vice President & General Manager, Imaging Systems Division, Global MedTech Inc.
In high-end imaging equipment, structure is no longer a 'supporting actor' but a critical link in the imaging chain. AntCarbonfiber's deep understanding of medical imaging physics, combined with their world-class composite engineering capabilities, helped us overcome the artifact challenge that has long plagued the industry. This carbon fiber gantry isn't just lighter and stronger—it fundamentally raises the imaging performance ceiling of our next-generation platform by at least an order of magnitude.
