  • Patent number: 10895615
    Abstract: A balun is provided that is suitable for use with miniature coaxial cables and that obviates the need to cut the cable in order to install the balun. A portion of each coaxial cable that extends from the RF receive coils to the RF receiver is wound multiple times around a device to form an inductor. The inductor may be used with or without a separate resonant circuit. If used with a separate resonant circuit, the inductor and the resonant circuit couple with one another to generate a coupled impedance that provides common-mode noise suppression at the frequency of interest. If used without a separate resonant circuit, the inductor formed in the cable provides an inductance and the capacitance between the windings coupled with the inductance provides a series impedance that suppresses common-mode noise at the frequency of interest.

  • Patent number: 10890632
    Abstract: To avoid the complication of an MRI apparatus and avoid the overestimation of a calculated value of SAR without extending a processing time and to perform accurate SAR management. To this end, the MRI apparatus is equipped with a high frequency antenna which has a plurality of channels and resonates at a predetermined frequency, and a measuring instrument which measures the amplitudes of a forward traveling and reflected waves of each high frequency signal supplied to the high frequency antenna. In the MRI apparatus, a reflection matrix S is determined based on the measured amplitudes. Diagonal terms of the determined reflection matrix S are used to calculate Q values for each of the channels. Each non-diagonal term of the reflection matrix S is used to correct the calculated Q value.

  • Patent number: 10888247
    Abstract: In a method for filtering magnetic resonance (MR) image data, complex MR image data is acquired from a region to be imaged, and a sliding window averaging is applied to the complex MR image data to generate filtered MR image data. For each window position of the sliding window averaging: a phase variation of the complex MR image data of individual image points of a sliding window is estimated with a model using a linear phase progression, and filtered complex MR image data is generated based on the estimated phase variation of the complex MR image data. The generation of the filtered complex MR image data uses an average formation of the complex MR image data of the individual image points of the sliding window.
