Accelerated Simultaneous Multislice Imaging via Linear Phase Modulated Extended Field of View (SMILE) - A simplified explanation of the abstract

This abstract first appeared for US patent application 18420104 titled 'Accelerated Simultaneous Multislice Imaging via Linear Phase Modulated Extended Field of View (SMILE)

The patent application describes a method for simultaneous multislice (SMS) magnetic resonance imaging (MRI) acquisition and image reconstruction using an MRI apparatus.

  • Exciting multiple imaging slices simultaneously with a phase modulation strategy to distribute image content over an extended phase-encoding field of view (FOV).
  • Acquiring data from the multiple slices using a sampling strategy that includes a k-space under-sampling pattern over an extended phase-encoding FOV k-space matrix.
  • Reconstructing images comprising the multiple slices over the extended phase-encoded FOV using an image reconstruction technique.

Potential Applications: - Medical imaging for faster and more efficient MRI scans. - Research applications in neuroscience, cardiology, and other fields requiring detailed imaging.

Problems Solved: - Allows for faster MRI scans by acquiring data from multiple slices simultaneously. - Improves imaging efficiency by distributing image content over an extended FOV.

Benefits: - Reduced scan times for patients. - Enhanced image quality and resolution. - Increased efficiency for researchers and clinicians.

Commercial Applications: Title: Advanced MRI Technology for Faster Imaging This technology could be used in hospitals, research institutions, and imaging centers to improve MRI efficiency and patient throughput. It could also be valuable for pharmaceutical companies conducting imaging studies.

Questions about MRI Technology: 1. How does this method improve the efficiency of MRI scans? This method allows for the simultaneous acquisition of data from multiple slices, reducing scan times and improving overall imaging efficiency.

2. What are the potential applications of this SMS MRI technology? This technology has applications in medical imaging for diagnosing various conditions, as well as in research settings for studying the structure and function of the human body.


Original Abstract Submitted

A method for simultaneous multislice (SMS) magnetic resonance imaging (MRI) acquisition and image reconstruction includes a) using an MRI apparatus, simultaneously i) exciting multiple imaging slices with a phase modulation strategy used to distribute the image content over an extended phase-encoding field of view (FOV), and ii) acquiring data from the multiple slices using a sampling strategy comprising a k-space under-sampling pattern over an extended phase-encoding FOV k-space matrix; and b) reconstructing images comprising the multiple slices over the extended phase-encoded FOV using an image reconstruction technique.
