SOMS: Simultaneous Orthogonal Multi- Slice Imaging
نویسندگان
چکیده
Simultaneous multi -s l ice (SMS) MRI has become a popular technique in both research and cl inical practice, as i t provides information about multiple sl ices at the time of a conventional s ingle-sl ice measurement. For technical reasons, SMS is commonly l imited to the acquisi tion of paral lel s l ices. Here, we propose a new Cartesian sequence for the simultaneous excitation of orthogonal s l ices. We dub this technique simultaneous orthogonal multi -s l ice (SOMS). In this proof of concept phantom study, we reconstruct two 2fold undersampled, s imultaneously acquired orthogonal s l ices.

Accelerated Diffusion Tensor Imaging of Skeletal Muscle Using Simultaneous Multi-Slice Acquisition
Simultaneous multi-slice acquisition with CAIPIRINHA reduces the scan time in diffusion-weighted magnetic resonance imaging. In this article, we resume our early experience with this technique for accelerated diffusion tensor imaging of skeletal muscle [1].

Dynamic MRI usually uses echo-planar imaging (EPI) [1] to achieve high temporal resolution. In brain imaging, modern MRI systems can achieve 3D spatial encoding with the whole-brain coverage using multi-slice EPI with TR of 2 s. A significant amount of time of multi-slice EPI is spent over k-space traversal. Recently, we proposed the MR inverse imaging (InI) [2] to achieve the unprecedented tem...
متن کاملWideband MRI: A New Dimension of MR Image Acceleration
We propose a new paradigm of MRI acceleration using the frequency multiplexing technique in modern communication technology; we name it “Wideband MRI”. A major component of wideband MRI is frequency multiplexing of MR signals. Using simultaneous multi-slice RF excitation pulses centered at different frequencies followed by simultaneous multi-slice acquisition during readout, the total scan time...
متن کاملImproving diffusion MRI using simultaneous multi-slice echo planar imaging
In diffusion MRI, simultaneous multi-slice single-shot EPI acquisitions have the potential to increase the number of diffusion directions obtained per unit time, allowing more diffusion encoding in high angular resolution diffusion imaging (HARDI) acquisitions. Nonetheless, unaliasing simultaneously acquired, closely spaced slices with parallel imaging methods can be difficult, leading to high ...
متن کاملRadial 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...
