Controlled Aliasing In Parallel Imaging

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

The CAIPIRINHA (Controlled Aliasing In Parallel Imaging Results IN Higher Acceleration) concept in parallel imaging has recently been introduced, which modifies the appearance of aliasing artifacts during data acquisition in order to improve the subsequent parallel imaging reconstruction procedure. This concept has been successfully applied to simultaneous multi-slice imaging (MS CAIPIRINHA). I...

Controlled aliasing in parallel imaging results in higher acceleration (CAIPIRINHA) for multi-slice imaging.

In all current parallel imaging techniques, aliasing artifacts resulting from an undersampled acquisition are removed by means of a specialized image reconstruction algorithm. In this study a new approach termed "controlled aliasing in parallel imaging results in higher acceleration" (CAIPIRINHA) is presented. This technique modifies the appearance of aliasing artifacts during the acquisition t...

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

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...

Radial simultaneous multi slice imaging for rapid cardiac imaging

Background It may be possible to more rapidly acquire cine, cardiac perfusion, and Late Gadolinium Enhancement (LGE) images for “free” with Simultaneous Multi-Slice (SMS) methods. With SMS imaging, multiple slices are simultaneously excited and acquired. Here we explore the application of an undersampled radial SMS approach termed Controlled Aliasing In Parallel Imaging results in higher accele...
