10.5 T In Vivo Head Imaging With Universal RF Shimming

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2776-2785, May 2026.
ABSTRACT Purpose Brain MR imaging at 10.5 T ultra‐high field offers significant improvements in signal‐to‐noise ratio (SNR), but faces challenges with B1+ inhomogeneity. Parallel‐transmission (pTx) can be used to achieve a more uniform RF field distribution, but necessitates the use of B1+ calibration in the region of interest.

Development of electron source feedback for enhanced X‐ray beam stability at NSLS‐II

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 585-595, May 2026.
An electron‐source feedback method has been demonstrated at the NSLS‐II Hard X‐ray Nanoprobe, using X‐ray beam position data to drive electron beam corrections. The approach suppresses dominant vibration peaks and significantly improves X‐ray beam stability and ptychographic image quality.Future synchrotron light sources are being designed to deliver ...
