1. A peripheral system for acquiring physiological data associated with an examination object that is disposed inside a radio frequency (RF)-shielded room that at least partially encloses a magnetic resonance device, the system comprising:
peripheral acquisition circuitry disposed inside the RF-shielded room, the peripheral acquisition circuitry comprising a peripheral data sensor configured to acquire the physiological data, a peripheral transmitter configured to transmit the physiological data, and a peripheral receiver;
peripheral control circuitry communicatively coupled to the peripheral acquisition circuitry via a first wireless connection using a first frequency; and
a door sensor configured to identify an opening status of a door associated with an RF shield of the RF-shielded room, the door sensor being communicatively coupled to the peripheral receiver via a second wireless connection using a second frequency,
wherein the peripheral acquisition circuitry is configured to switch off the peripheral transmitter when the identified opening status of the door indicates that the door is open.
