  • Pre-emphasis techniques based on temperature dependent gradient system behavior for trajectory correction in magnetic resonance imaging
    Patent number: 11112472
    Abstract: A gradient system characterization function (e.g., a gradient system transfer function) may be developed by measuring a behavior of the MR device at a target temperature and developing at least one gradient system characterization function for a gradient coil of a magnetic resonance (MR) device at the target temperature based on the measured behavior. A patient may be subsequently imaged by the MR device, wherein the imaging process comprises measuring a temperature of a gradient coil, determining a gradient system characterization function at the measured temperature, calculating a pre-emphasized gradient of the gradient coil, and imaging the patient using the pre-emphasized magnetic field component.

  • PRE-EMPHASIS TECHNIQUES BASED ON TEMPERATURE DEPENDENT GRADIENT SYSTEM BEHAVIOR FOR TRAJECTORY CORRECTION IN MAGNETIC RESONANCE IMAGING
    Publication number: 20200333410
    Abstract: The disclosure relates to methods, devices, and systems for developing gradient system characterization functions and imaging a patient using pre-emphasized magnetic field components in a magnetic resonance (MR) device, wherein the processes allow for a reduction in a number of artifacts when reconstructing the magnetic resonance image. The gradient system characterization function (e.g., a gradient system transfer function) may be developed by measuring a behavior of the MR device at a target temperature and developing at least one gradient system characterization function for a gradient coil of the MR device at the target temperature based on the measured behavior.
