A product will only become a "good product" if it is used successfully in the intended application environment.

When a complex customer project has gone through all phases from start to completion and the customer-specific monitor solution has been manufactured, its true purpose comes into play: Its application!

Only here, in the real operation under realistic environmental conditions, the design, conception, components and the entire system must prove itself. Only if this is successful, our customer will finally speak of success!

Our customer-specific display solutions have been successful for decades in the most diverse applications and markets.

Cardiovascular Imaging and Visualization

(#Not approved) Cardiovascular Imaging and Visualization

The customer here is the global leader in cardiovascular care, providing low invasive devices for the treatment of coronary artery disease. Their philosophy is to deliver high quality devices with unique and innovative technology. They offer a comprehensive device portfolio including products for the diagnosis and treatment of coronary artery disease.

The Main Application:

Medical cart system which provides intravascular imaging and visualization. The system is mainly used in coronary intervention to verify both stent position and blood vessels’ condition.

Challenge and Description of the Project:
Customer’s arterial imaging system was moving to NextGen as well as resolving an End Of Life (EOL) issue with the legacy monitor. The legacy monitor used CCFL technology (essentially obsolete) that did provide the customer / application with a crisp black and white image, a critical parameter for the application.

The customer had requirements to maintain same color ‘temperature’ and brightness for ease of retrofit and to minimize retraining impact for the medical personnel using the system. Use of system power (not Canvys power supply) required re-certification for UL and re-testing to 60601 EMI standards. Transition to the new monitor solution was to be as transparent to the operator / installation as possible.

The Canvys engineering team, along with program management, sales and manufacturing team engaged with the customer to develop a solution that would meet system requirements. To minimize engineering time and expense, an existing monitor was chosen for a production baseline. A specification for optical performance to match the legacy product was developed, including parameters for brightness uniformity, chromaticity / color temperature, max brightness, and intensity / luminance. To ensure conformance to this specification (less than 10 % variation on each parameter), a calibration and validation test has been implemented for 100 % of production units. In addition, per customer request, Canvys created custom firmware for the monitor to disable typical ‘auto-off’ / power safe functionality as this would be disruptive to the system implementation.

To allow for the customer to use their existing power supply, Canvys recertified the product with UL and worked with the customer throughout their system level IEC 60601 and ESD test processes.

How customers use our customized solutions as components within their systems varies significantly by customer. Regulatory compliance is the sole responsibility of the customer. Neither Canvys nor Richardson Electronics, Ltd. or any of its subsidiaries have any responsibility or liability for such compliance.
