Patent ID: 11946990

Abstract:
A magnetic resonance imaging, MRI, system (2), comprises MRI electronics, including a transmitting coil (11) for transmitting radio frequency, RF, signals and a receiving coil (12) for receiving RF signals; and/or a transmitting/receiving coil (3) for transmitting and receiving RF signals; and cables (22), connecting the transmitting coil (11), receiving coil (12) and/or transmitting/receiving coil (3) to other electronic elements. The MRI system (2) further comprises an overheating detection unit to detect potential overheating of a patient's (1) tissue and/or a part of the MRI system (2) caused by at least one part of the MRI electronics; and a distance unit (16), wherein the distance unit (16) comprises a gas chamber (5), to be arranged between the at least one part of the MRI electronics and the patient (1) and/or between the at least one part of the MRI electronics and the part of the MRI system (2) and adapted to be filled with a gas such that a distance between the patient (1) and the part of the MRI electronics and/or between the part of the MRI system (2) and the part of the MRI electronics increases when the gas chamber (5) is filled with the gas, wherein the gas chamber (5) is in a deflated state when no significant overheating is detected, and an inflation unit (15) to fill the gas chamber (5) with the gas, wherein the overheating detection unit and the distance unit (16) are interconnected such that the inflation unit (15) fills the gas chamber (5) with the gas to increase the distance between the patient (1) and the part of the MRI electronics and/or between the part of the MRI system (2) and the part of the MRI electronics if the overheating detection unit detects significant overheating of the patients (1) tissue and/or the part of the MRI system (2).
