摘要:
Techniques for removing artefacts, such as RF interference and/or noise, from magnetic resonance data. The techniques include: obtaining input magnetic resonance (MR) data using at least one radio-frequency (RF) coil of a magnetic resonance imaging (MRI) system; and generating an MR image from input MR data at least in part by using a neural network model to suppress at least one artefact in the input MR data.
摘要:
A system and method for determining electrical properties using Magnetic Resonance Imaging (MRI) are provided. One method includes determining a magnitude of an MRI B1+ field applied to an object, determining a phase of the MRI B1+ field applied to the object and combining the determined magnitude and phase to determine a complex B1+ field estimate. The method further includes estimating one or more electrical properties of the object using the complex B1+ field estimate by directly solving at least one difference equation.
