    摘要: A thermal management system for cooling a heat generating component of a Magnetic Resonance Imaging (MRI) apparatus includes at least one heat pipe having a portion disposed proximate the heat generating component, such as a gradient coil and/or RF coil. When heat is removed from the component, a working fluid in a relatively hotter end of the heat pipe vaporizes and travels toward a relatively colder end of the heat pipe. The colder end may be operatively coupled to a heat sink for removing the heat from the colder end and increase the overall efficiency of the system. The heat pipe may be disposed along a horizontal, a vertical direction and/or along a diagonal of the heat generating component.

    摘要: Methods, systems and computer program products are described for providing gradient linearity correction in a magnetic resonance image. The method in one example obtains, using a simulation, a time-dependent eddy current induced magnetic gradient field produced by a gradient system in response to a gradient switching pulse. Subsequently, the method determines time-dependent eddy current harmonic response coefficients for at least one higher harmonic frequency based upon the time-dependent eddy current induced magnetic gradient field. The method then corrects the magnetic resonance image based upon the time-dependent eddy current harmonic response coefficients.
