Method for Improved Phase Contrast MRI Resolution

This invention is a method to significantly improve the temporal or spatial resolution in a phase contrast MRI (PC-MRI) study. In general, conventional PC-MRI involves encoding the motion information of spins in the phase of the image. The velocity of the spin motion can be extracted by calculating the phase difference between two consecutive images...

Novel Method of Fat Suppression in Steady State Free Precession (SSFP) Based Magnetic Resonance Imaging (MRI)

Available for licensing is a technique for improving magnetic resonance imaging (MRI) that employs steady state free precession (SSFP). One such technique, fast imaging with steady-state free precession (FISP), is a well established and is a fast MR imaging method commonly used to evaluate cardiovascular anatomy and function. FISP provides high signal...

Method and Apparatus to Improve an MRI Image

The invention is a method for improving image quality in MR imaging methods using the SENSE (SENSitivity Encoding) method, which is known to have degraded image quality due to numerical ill-conditioning (so called g-factor loss). The invention improves the numerical conditioning by means of an adaptive regularization (matrix conditioning), thereby improving...

Generalized MRI Artifact Reduction Using Array Processing Method

The invention is a phased array combining method for reducing artifacts in Magnetic Resonance (MR) imaging. The method uses a constrained optimization that optimizes signal-to-noise subject to the constraint of nulling ghost artifacts at known locations. The method is effective in reducing or canceling artifacts that arise in a wide variety of MR...

Real Time Interactive Volumetric Magnetic Resonance Imaging

The invention makes possible "live" volume renderings from a Magnetic Resonance Imaging (MRI) scanner. Previously, volume renderings from MRI data could only be generated off-line, some time after the image data was collected. In one embodiment of the invention, the time between data collection and volume rendering update (the latency) is approximately...

Adaptive Sensitivity Encoding Incorporating Temporal Filtering (TSENSE)

The invention is an accelerated magnetic resonance imaging method developed to reduce the total imaging time for gated, segmented cine imaging or to increase the frame rate when imaging dynamic activity, such as heart motion or brain activity. The invention combines temporal filtering (e.g., the UNFOLD method) with a known spatial sensitivity encoding...
