Parallel Magnetic Resonance Imaging Reconstruction
The acquisition speed of magnetic resonance imaging (MRI) is an important issue. Increasing the acquisition speed shortens the total patient examination time, it reduces motion artifacts and increases the frame rate of dynamic MRI. Parallel MRI is a way to use multiple receiver coils with distinct spatial sensitivities to increase the MRI acquisition speed. The acquisition is speeded up by unde...
متن کاملGradient waveform design for variable density sampling in Magnetic Resonance Imaging
Fast coverage of k-space is a major concern to speed up data acquisition in Magnetic Resonance Imaging (MRI) and limit image distortions due to long echo train durations. The hardware gradient constraints (magnitude, slew rate) must be taken into account to collect a sufficient amount of samples in a minimal amount of time. However, sampling strategies (e.g., Compressed Sensing) and optimal gra...
متن کاملParallel magnetic resonance imaging.
Parallel imaging has been the single biggest innovation in magnetic resonance imaging in the last decade. The use of multiple receiver coils to augment the time consuming Fourier encoding has reduced acquisition times significantly. This increase in speed comes at a time when other approaches to acquisition time reduction were reaching engineering and human limits. A brief summary of spatial en...
متن کاملParallel Magnetic Resonance Imaging
The main disadvantages of Magnetic Resonance Imaging (MRI) are its long scan times and, in consequence, its sensitivity to motion. Exploiting the complementary information from multiple receive coils, parallel imaging is able to recover images from under-sampled k-space data and to accelerate the measurement [1, 2, 3, 4, 5, 6, 7]. Because parallel magnetic resonance imaging can be used to accel...
