Fusing Multiple Multiband Images [PDF]

Journal of Imaging, 2018
High-resolution hyperspectral images are in great demand but hard to acquire due to several existing fundamental and technical limitations. A practical way around this is to fuse multiple multiband images of the same scene with complementary spatial and spectral resolutions.

Navigator-Based Slice Tracking for Multiband Accelerated Liver DWI. [PDF]

Magn Reson Med
ABSTRACT Purpose Clinical liver diffusion‐weighted imaging (DWI) suffers from long measurement time and respiratory motion. In this study, we employ a navigator‐based slice tracking technique (NAV) to prospectively compensate for respiratory motion in multiband (MB) accelerated liver DWI.
