Abstract
A thermo-isolating jacket for a magnetic resonance device (MRD). The thermo-isolating jacket is configured to be positioned in an atmospheric pressure, temperature changing environment. The thermo-isolating jacket provides a passive temperature insulating device to be placed on the outer side of the MRD. The thermo-isolating jacket insulates the MRD from external environment temperature fluctuations during its operation.
