In parallel MR imaging, a reduced data set in the phase encoding direction(s) of k-space is acquired to shorten acquisition time, combining the signal of several coil arrays. The spatial information related to the phased array coil elements is utilized for reducing the amount of conventional Fourier encoding.
First, low-resolution, fully Fourier-encoded reference images are required for sensitivity assessment. Parallel imaging reconstruction in the Cartesian case is efficiently performed by creating one aliased image for each array element using discrete Fourier transformation. The next step then is to create an full FOV image from the set of intermediate images.
Parallel reconstruction techniques can be used to improve the image quality with increased signal to noise ratio, spatial resolution, reduced artifacts, and the temporal resolution in dynamic MRI scans.
Parallel imaging algorithms can be divided into 2 main groups:
Image reconstruction produced by each coil ( reconstruction in the image domain, after Fourier transform): SENSE ( Sensitivity Encoding), PILS (Partially Parallel Imaging with Localized Sensitivity),
ASSET.
Reconstruction of the Fourier plane of images from the frequency signals of each coil ( reconstruction in the frequency domain, before Fourier transform): GRAPPA. Additional techniques include SMASH, SPEEDER™,
IPAT (Integrated Parallel Acquisition Techniques - derived of GRAPPA a k-space based technique) and mSENSE (an image based enhanced version of SENSE).

SPEEDERâ„¢ is Toshiba's patented parallel imaging technology for high-speed imaging. This technique reduces examination time for MRI studies by a factor of up to three while enabling clinicians to capture high-quality images with detailed diagnostic information. With SPEEDERâ„¢, cardiac and MRA examinations are more patient-friendly and tolerable with shorter scan times and improved image quality.
