  1. A Reconstruction Program for Radial Magnetic Resonance Imaging Data Jessica Bernier The Bruker Biospec 7 Tesla Small animal MRI scanner

  2. Histology Section MRI image Motivation: Alzheimer’s Research Control PS/APP Images of the ex vivo brain, reconstructed with FBPR. Dark spots correspond to the presence of Aβ plaque.

  3. The Ultrafast Echo-Time (UTE) Pulse Sequence kz ky kx

  4. ky y kx x Fourier Transforms(on a need-to-know basis)

  5. Results of the 2D NUFFT Complex Magnitude FBPR NUFFT

  6. Developing the 3D NUFFT

  7. The importance of a proper density weighting function

  8. Radially-accelerated data

  9. Future Work Acknowledgments • Density compensation for radially accelerated data • Apply to UTE pulse sequence • M.I.T! • Dr. Ted Trouard, my Honors Thesis supervisor • John Totenhagen and Eriko Yoshimaru • UBRP (Undergraduate Biology Research Program)
