What is it indicated for?

The Sentinel system is intended for use in radiation therapy clinics to accurately position patients in a reproducible way, prior to treatment and to monitor the patient continuously during treatment. The system provides information about a patient's position and the adjustments required in order to position the patient as close as possible to a reference setup. During monitoring, the system reports deviations in the patient's position during treatment. The system shall only be used by hospital personnel, qualified to work in radiation therapy or diagnostics departments.

Indications for use as stated in the FDA summary.
