Controlled aliasing in volumetric parallel imaging (2D CAIPIRINHA).

Controlled Aliasing In Parallel Imaging

Recently a new parallel imaging strategy, Controlled Aliasing In Parallel Imaging Results IN Higher Acceleration (CAIPIRINHA), was introduced, which modifies the appearance of the aliasing artifacts during the acquisition in order to improve the following parallel imaging reconstruction procedure. This concept was successfully applied to simultaneous multi-slice imaging (MS-CAIPIRINHA) [1] and ...

Optimizing the undersampling scheme of 2D Controlled Aliasing in Parallel Imaging Results in a Higher Acceleration (CAIPIRINHA) in Abdominal Imaging using 3D g-factor map: A phantom study

Highly accelerated T1-weighted abdominal imaging using 2-dimensional controlled aliasing in parallel imaging results in higher acceleration: a comparison with generalized autocalibrating partially parallel acquisitions parallel imaging.

PURPOSE The purpose of this study was to evaluate the feasibility and technical quality of an abdominal 3-dimensional interpolated breath-hold (volumetric interpolated breath-hold examination [VIBE]) magnetic resonance examination using the new parallel acquisition technique, controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA). MATERIALS AND METHODS In this ins...

Controlled aliasing in 3D parallel imaging (2D CAIPIRINHA)

A new approach to improve image quality in partially parallel 3D MRI is presented. Aliasing artifacts are manipulated by modifications of the gradient tables in the 3D phase encoding direction in order to achieve improved conditions for the final image reconstruction procedure. In contrast to conventional 3D parallel imaging methods, like 2D SENSE [1], superimposed partitions with essentially i...

A 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...
