Overview

Laser positioning systems project reference lines to align patients with imaging coordinates. They improve reproducibility and reduce setup time for CT MRI and radiography. Accurate positioning supports image quality and radiation safety.

Types and Features

Systems include crosshair sagittal and coronal lasers with adjustable brightness. Some systems integrate with immobilization devices and table controls. Compatibility with modality workflows enhances efficiency.

Calibration and Safety

Laser alignment must be calibrated to imaging isocenter regularly. Safety protocols prevent direct eye exposure and ensure proper mounting. Documentation of calibration supports QA programs.

Clinical Use

Lasers assist in planning radiotherapy simulation and repeat imaging studies. They reduce variability in serial imaging and improve registration. Training ensures consistent use across staff.
