Precision control for medical X-Ray technology
Winter and Smith collaborated on the development of a sophisticated control system for a PXS11 X-Ray source, designed for medical applications. This innovative machine required a power supply and advanced electronics to regulate and configure X-ray outputs, ensuring precise control of kilovolts (kV) and milliamps (mA) for optimal imaging quality.
Our role encompassed full-scale development, including electronics design, mechanical engineering, software development, and system integration. The goal was to create an intuitive and reliable interface that would convert and display real-time X-ray parameters, improving ease of use for medical professionals.
What was involved?
- Design of bespoke medical electronics
- Electronics design of medical testing system
- PCB Assembly
- Embedded software for medical devices
- EMC/CE testing of medical device
- CNC panel machining and engraving
- Packaging design for medical electronics
Understanding the requirements: power, precision, and safety
Medical imaging requires extreme accuracy and safety measures. The client needed a system capable of:
- Fine-tuned control over X-ray output, allowing adjustments to kV and mA.
- Real-time monitoring and digital display, ensuring clarity in operation.
- A robust and medically compliant power system, integrating seamlessly with the PXS11 X-ray source.
- A user-friendly interface, simplifying calibration and adjustments for technicians.
After reviewing the client’s requirements, we designed a proposal outlining the technical architecture, regulatory considerations, and the development approach.
Electronic design
To control the X-ray source, we developed a microprocessor-driven system that monitored and adjusted power levels in real time. The key innovations included:
- Analog-to-digital conversion of X-ray output signals, ensuring precise measurement and adjustments.
- Custom circuit board design, optimised for medical-grade reliability and performance.
- Integrated fail-safes, preventing voltage fluctuations and ensuring consistent imaging quality.
The microprocessor handled complex signal processing, converting raw data into meaningful metrics displayed on the control panel.
Mechanical design
Medical equipment must be both ergonomic and durable. Our mechanical engineers designed an enclosure that:
- Housed all power electronics and controls securely, minimising interference and ensuring long-term reliability.
- Allowed for easy accessibility, ensuring maintenance and calibration could be performed without hassle.
- Met medical safety regulations, protecting users from high-voltage components.
Software development
The software for this system had to:
- Convert raw analogue signals into easy-to-read digital values for kV and mA.
- Provide real-time monitoring and adjustments, ensuring medical technicians had complete control.
- Ensure accuracy and stability, preventing erratic readings or unsafe conditions.
We developed an intuitive interface that displayed all critical values on an alphanumeric front panel, allowing medical professionals to monitor the system at a glance.
Final build and testing
Once the electronics, mechanical components, and software were integrated, we conducted rigorous testing to verify:
- Accuracy of X-ray power adjustments
- Stability of long-term operation
- Compliance with medical safety standards
Following successful testing, the system was delivered and deployed for use in medical imaging applications!
