High efficiency, high frequency magnetic deflection driver [PDF]
, 1968 Electromagnetic deflection yoke stores energy during the scan and releases it in the flyback or retrace. The operation of the device involves a method of switching to a voltage high enough to dissipate the flyback pulse during the retrace time and then ...

Highly Reproducible, Vendor‐Agnostic, Motion‐Insensitive Liver PDFF Mapping at 0.55T, 1.5T, and 3T
Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2797-2813, May 2026.ABSTRACT Purpose To develop and validate a vendor‐agnostic, motion‐insensitive proton‐density fat‐fraction (PDFF) quantification method. Methods Flip‐angle‐modulated (FAM) 2D chemical‐shift‐encoded (CSE) MRI for PDFF quantification was implemented in both the vendor‐agnostic platform Pulseq (“Pulseq‐FAM”) and one vendor‐specific platform (“GE‐specific ...

Optimized motion‐insensitive PDFF mapping of the liver
Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 249-267, January 2026.Abstract Purpose To implement, optimize, and validate parallel imaging (PI)‐accelerated, 2D, flip angle modulated (FAM) chemical shift‐encoded quantification of liver proton‐density fat fraction (PDFF), with motion insensitivity. Methods The optimization cost function that determines flip angles in FAM was generalized for PI.
