Technical details and manufacturing context for Optical Sensor Array / Electronic Distance Measurement (EDM) Unit

Definition
This unit serves as the core measurement component within an Isocenter Verification System, specifically designed for medical linear accelerators and radiation therapy equipment. It integrates an array of optical sensors with electronic distance measurement (EDM) capabilities to precisely determine the spatial position of the radiation beam's isocenter - the critical point where all treatment beams converge. The system ensures accurate patient positioning and treatment delivery by continuously monitoring and verifying the mechanical and radiation isocenter alignment.
Working Principle
The optical sensor array detects reference markers or fiducials using infrared or visible light, while the EDM subsystem employs phase-shift or time-of-flight measurement principles to calculate precise distances. Data from both subsystems are processed through triangulation algorithms to determine three-dimensional coordinates relative to the treatment machine's coordinate system.
