Methods and systems are provided for cooling hot spots on a body coil assembly of an MRI system. In one embodiment, an airflow guide of a body coil assembly of an MRI system comprises a first surface that forms an air passage when the airflow guide is positioned on the body coil assembly, the air passage enclosed by the first surface and a second, outer surface of an RF coil of the body coil assembly, the airflow guide configured to channel cool air generated by a fan to the second, outer surface of the RF coil. The airflow guide may be arranged circumferentially around a portion of the RF coil at one or more ends of the RF coil. The airflow guide may be manufactured as a plurality of airflow guide segments that are glued together.

Systems and methods for body coil air cooling

The embodiments disclosed herein relate generally to magnetic resonance imaging systems and, more specifically, to the manufacturing of a gradient coil assembly for magnetic resonance imaging (MRI) systems. For example, in one embodiment, a method of manufacturing a gradient coil assembly for a magnetic resonance imaging system includes depositing a first layer comprising a base material onto a surface to form a substrate and depositing a second layer onto the first layer. The second layer may enable bonding between a conductor material and the substrate. The method also includes depositing a third layer onto the second layer using a consolidation process. The consolidation process uses the conductor material to form at least a portion of a gradient coil.

A method, system, and apparatus including a magnetic resonance (MR) coil system that includes an MR coil element, a high input Pre-amplifier having a high input impedance field-effect-transistor (FET) with an impedance of one of substantially equal to 500 ohms and greater than 500 ohms, and a conductive path. The conductive path has a first end coupled to the MR coil element and a second end coupled to the high input Pre-amplifier such that the MR coil element is coupled in series with the high input Pre-amplifier. Further, the conductive path is free of a matching network intervening between the MR coil element and the high input Pre-amplifier.

Three MRI acquisitions are performed to acquire data from which separate water and fat images may be reconstructed using a three-point Dixon technique. The NMR data is acquired with a phased array coil having four separate coil elements. Low resolution images are reconstructed from the acquired NMR data sets and used to calculate phase corrections which are used to correct reconstructed high resolution images. The corrected high resolution images are processed using the Dixon technique to produce fat and water images for each coil element which are combined into a single fat and a single water image.

Monitor signals are acquired in an interleaved manner during a scan with an MRI system. Frequency changes caused by variations in the polarizing magnetic field B,are measured using the monitor signals, and these measured frequency changes are employed to compensate image data acquired during the scan.
