Laser alignment lights

The MR systems use semiconductor laser alignment lights for patient land marking. This type of alignment light casts a thin red light on the patient for the purpose of positioning and land marking. The laser lights can cause eye injury. The figures below display the safety labels for laser products and are located near the laser alignment light. Labels such as these provide safety information about laser radiation.

Note: Your system may have a slight variation of these labels.

The eyes must be protected from laser radiation. The patient needs to be instructed to close their eyes when landmarking and the laser light is turned on. Exposing eyes to the laser alignment lights may result in eye injury.

CAUTION

Exposing eyes to laser alignment lights may result in eye injury.

Do not stare directly into the laser beam.
Instruct patients to close their eyes to avoid eye exposure to the alignment light.
Closely monitor all patients and prevent them from accidentally staring into the beam. Do not leave the laser beam on after you position the patient.
