Abstract: A method of processing magnetic resonance imaging signals from a plurality of receiver coils of a magnetic resonance imaging system, comprises the steps of receiving from said plurality of receiver coils a corresponding plurality of original signals in the time-domain forming an n-dimensional signal vector ?k wherein n is the number of receiver coils; linearly combining said original signals so as to obtain a plurality of transformed signals forming an m-dimensional transformed signal vector ??k wherein m is smaller than n and wherein said step of linearly combining is represented by a linear transformation matrix A; and reconstructing an image from said plurality of transformed signals.

Abstract: This invention describes the combination of SSFP, a method for accelerating data acquisition, and an eddy current compensation method. This synergistic combination allows acquisition of images with high signal-to-noise ratio, high image contrast, high spatial and temporal resolutions, and good immunity against system instabilities. k-t BLAST and k-t SENSE are the preferred method for accelerating data acquisition, since they allow high acceleration factors, but other methods such as parallel imaging and reduced field-of-view imaging are also applicable. Typical applications of this invention include cine 3D cardiac imaging, and 2D real-time cardiac imaging.

Abstract: Two different RF-frequency ranges or bands are employed viz. at the localisation RF-frequency and at the imaging RF-frequency, respectively. At these respective RF-frequency ranges different types of magnetic resonance signals are acquired. At the localisation RF-frequency a high sensitivity for the position of the interventional device is achieved. At the imaging RF-frequency a high sensitivity for image information, i.e. contrast resolution, of the anatomical structures of the patient to be examined is achieved.

Abstract: The present invention describes a magnetic resonance imaging method wherein spatially resolved frequency sensitive image data are collected by means of free precession sequences employing very small radio frequency (RF) excitation pulses per unit time which result in highly frequency selective steady-state signals dominated by linear properties of the system, for which the superposition principle holds. By appropriate linear combination of steady state signals of N different frequencies, N resonance lines can be acquired simultaneously. This method allows spectroscopic recordings with very low RF power deposition which renders the method suitable for applications at high static magnetic field strengths.

Abstract: A novel combination of free-breathing navigator-gated 3D coronary magnetic resonance angiography with SENSE imaging is described. Applying a SENSE reduction factor of two at a main magnet field of 3 T allows to image long portions of the left and the right coronary artery system during half of the scan time, when compared to normal acquisition.
