Technical details and manufacturing context for Laser Positioning System

Definition
The Laser Positioning System is a critical component of the Radiation Therapy Simulator that projects multiple visible laser beams (typically red or green) onto the patient's skin to establish and verify precise positioning coordinates. It creates a three-dimensional reference grid that aligns with the treatment planning system, ensuring accurate patient setup by marking isocenter, field boundaries, and anatomical landmarks before radiation treatment delivery.
Working Principle
The system uses low-power laser diodes that emit coherent light beams through precision optical lenses and mirrors. These beams are projected from fixed positions on the simulator gantry and walls to intersect at the treatment isocenter. The lasers are precisely calibrated to align with the imaging system's coordinate system, creating reference planes (sagittal, coronal, and transverse) that help position the patient within sub-millimeter accuracy.
