Do users have to remove the Sensor during MRI/CT scan?
If the user has a medical appointment that includes strong magnetic or electromagnetic radiation, for example an X-ray, MRI (Magnetic Resonance Imaging), or CT (Computed Tomography) scan, they need to remove the Sensor they are wearing and apply a new Sensor after the appointment. The effect of these types of procedures on the performance of the system has not been evaluated.1
