Off-line balanced forward-flyback converter [PDF]

, 2016
Due to the flybacks' indirect characteristic of energy transfer, the transformer size increases for high power levels. Providing an additional direct energy transfer path can decrease its size. Parallel forward-flyback converters offer such functionality

Feasibility and SNR Performance of Hyperpolarized 129Xe Gas Exchange Imaging Using a Balanced SSFP Sequence

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a balanced SSFP (bSSFP) sequence for pulmonary 129Xe dissolved‐phase imaging based on a previously described double‐echo sequence facilitating separation into red blood cell and membrane signals, to test its feasibility and compare its SNR performance and imaging results to an analogous FLASH sequence.
