SOFTWARE CONTROLLED SHIM PULSES CORRECT FOR ARTIFACTS INDUCED BY HARDWARE (a) (b) (c) (a) A liquid sample in an 8 by 8 array of square wells spanning 20 by 20 mm in the x,y plane. Simulated images of the sample using (b) standard MRI methods and (c) positional encoding with the Berkeley Lab shim pulse method. The size of each square well in (b) corresponds to the … [Read more...] about Using Pulse Sequences to Achieve High Resolution NMR/MRI with Simplified Hardware IB-2026
