Superior GRAPPA reconstruction with reduced g-factor noise using 2D CAIPIRINHA for 3D EPI
نویسندگان
چکیده
different Δ shifts (A=0, B=3, C=2) in the slice encode direction for one sampling row Ky to the next. Corresponding k-space sampling patterns are also shown. All points belonging to a particular segment are acquired during a single readout echo train. Missing k-space points are empty squares whereas filled squares are acquired k-space points. Note that the length of the echo train is kept unchanged.

Improvement of temporal signal-to-noise ratio of GRAPPA accelerated echo planar imaging using a FLASH based calibration scan.
PURPOSE To demonstrate that the temporal signal-to-noise ratio (SNR) of generalized autocalibrating partially parallel acquisitions (GRAPPA) accelerated echo planar imaging (EPI) can be enhanced and made more spatially uniform by using a fast low angle shot (FLASH) based calibration scan. METHODS EPI of a phantom and human brains were acquired at 3 Tesla without and with GRAPPA acceleration f...
متن کاملA 3D GRAPPA algorithm for volumetric parallel imaging
Introduction: In volumetric parallel imaging, data reduction is carried out along two phase encoding directions, thereby exploiting sensitivity variations in two spatial dimensions and yielding improved parallel imaging reconstruction performance. In previous work, imagedomain based two-dimensional SENSE reconstruction methods have been presented for rectangular [1] and 2D CAIPIRINHA-type reduc...
متن کاملStack-of-Spirals CAIPIRINHA Trajectory for Rapid Volumetric Imaging
Target Audience: MRI physicists and engineers. Purpose: The stack-of-spirals trajectory has been shown to be a very time efficient method to traverse a volumetric k-space for high-resolution imaging (1). Rapid volumetric imaging is useful for high-resolution fMRI at high magnetic fields (2). The long scan times needed for high resolutions however can compromise the temporal resolution of the BO...
