MAGNETIC RESONANCE SYSTEM WITH COOLING SYSTEM AND MONITORING OF HELIUM PRESSURE
摘要
<p>A magnetic resonance examination system includes a main magnet with superconducting coils to generate a main magnetic field and a gradient system to apply a gradient magnetic field superposed on the main magnetic field. A cooling system cools the superconducting coils to below their critical superconductivity temperature. A transfer monitor assesses the transfer of energy from the gradient system to the cooling system. The transfer monitor is configured to measure pressure changes in the cooling system. This leads to a simple manner of evaluating the transfer of energy from the gradient coils into the cooling system.</p>
