AU200 replacement CT tube
Cost Savings Over OEM
Don’t let legacy constraints dictate your clinical outcomes. The AU200 delivers a 140 kV peak and 6.3 MHU anode heat capacity, providing the technical liberation your imaging system deserves.It meets Chronos replacement specifications and must be installed by qualified field service personnel in accordance with the CT system OEM guidance and the tube Instructions for Use (IFU).
The “Status Quo” in medical imaging is a budget drain. We understand the frustration of technical bottlenecks that stall patient care. The AU200 isn’t just a replacement; it’s a strategic upgrade. It replaces technical uncertainty with disruptive authority—delivering hospital-grade image quality without the high-cost grip of legacy OEM systems.
Precision Engineering: Dual focal spots (0.7 x 0.6 mm and 0.9 x 0.9 mm) ensure uncompromising clarity for critical diagnoses.
Thermal Resilience: With a 4.7 MJ (6.3 MHU) anode heat storage capacity, the AU200 is built for high-throughput environments where downtime is not an option.
Superior Material Science: Features a Beryllium window and a 200 mm (7.9 in) TZM-composition anode disk for optimized X-ray emission and heat dissipation.
Tested to IFU requirements: Product packaged and shipped with IFU documentation and recommended installation/warm-up instructions.
Note: This product is a component replacement for CT scanners. It is not intended by the manufacturer to be marketed with claims of diagnostic benefit or to replace imaging system clinical protocols. Follow the IFU and the scanner OEM service instructions for installation, warm-up, and QA.
Supports high patient throughput and extended scan cycles without overheating.
Rated performance per IFU; actual use should follow OEM operating limits.
Installs seamlessly in GE LightSpeed™ and Discovery™ systems using D3191T–D3199T tubes.
Mechanical and electrical interfaces match OEM specifications; verify before installation.
Designed and tested for stable anode rotation, consistent exposure quality, and long service intervals.
Tube life depends on scan protocol and maintenance conditions.
Compatible with existing mounting hardware, cables, and cooling systems.
Reduces field installation time; requires qualified personnel.
Provides confidence in component quality and manufacturing integrity.
Warranty coverage terms available upon quote.
Includes full Instructions for Use (IFU), safety guidance, and warm-up procedures.
Installation and calibration must follow IFU and OEM system requirements.
Each unit serialized for tracking, maintenance logging, and QA documentation.
Enables compliance with facility quality management systems.
Shock-protected, recyclable crate minimizes shipping risk.
Tube handling and disposal must follow IFU and regulatory guidelines.
Designed for precision, reliability, and ease of service, the AU200 delivers OEM-level compatibility for a range of GE CT platforms.
