Laser Positioning System
Laser Positioning System (LSP) is designed for precise and accurate patient alignment during X-ray and γ-ray treatment. The System consists of three boxes in which there are five modules with long life laser diodes (made in Japan). The System can work continuously for years without special servicing. Two boxes with the help of special cylindrical lenses generate light crosses on both sides of a table with a patient, the third one with light lines is for control of the table axis. The System is safely powered from a 5 V DC (special adapters 220V AC/5 V DC are included). Fine mechanical positioning rails are helpful for adjusting the System during installation and after that no special servicing is necessary.
