Physiological acquisition system for use in an RF-shielded room

A magnetic resonance (MR) device, comprising:

• a peripheral system configured to acquire physiological data associated with an examination object that is disposed inside a radio frequency (RF)-shielded room that at least partially encloses the magnetic resonance device, the peripheral 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;
• and
• a detector disposed inside the RF-shielded room and configured to receive MR signals from the examination object.

A method for examining an examination object using a magnetic resonance (MR) device, comprising:

• positioning the examination object in a radio frequency (RF)-shielded room;
• disposing peripheral acquisition circuitry on the examination object, 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, the peripheral acquisition circuitry being communicatively coupled to peripheral control circuitry via a first wireless connection using a first frequency;
• positioning the examination object in a patient receiving area at least partially enclosed by a detector;
• closing the door of the RF-shielded room;
• identifying, via a door sensor that is communicatively coupled to the peripheral receiver via a second wireless connection using a second frequency, an opening status of the door;
• acquiring physiological data of the examination object;
• and
• acquiring MR signals of the examination object,
• 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.
