SYSTEM AND METHOD FOR OPERATING MAGNETIC RESONANCE IMAGING SYSTEM DURING RAMPING |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide ramping of a magnetic resonance imaging (MRI ) system that does not add cost and complexity. <P>SOLUTION: Systems and methods for operating a magnetic resonance imaging (MRI) during ramping are provided. One method (30) includes a step (32) of reducing pressure in a cryogen vessel of the MRI system during magnet ramping. The method also includes a step (38) of returning pressure in the cryogen vessel to a normal operating pressure level after magnet ramping is complete. <P>COPYRIGHT: (C)2012,JPO&INPIT |
