Medical Physics, EarlyView.Abstract Background Ultra‐high dose rate, or FLASH, radiotherapy has shown promise in preclinical experiments of sparing healthy tissue without compromising tumor control. This “FLASH effect” can compound with dosimetric sparing of the proton Bragg peak (BP) using a method called Single Energy Pristine Bragg Peak (SEPBP) FLASH.

Magnetic Resonance in Medicine, EarlyView.Abstract Purpose In MR electrical properties tomography (EPT), conductivity and permittivity are reconstructed from MR measurements. However, depending on the reconstruction method, reconstructed electrical properties (EPs) show large variability in vivo, reducing confidence in the reconstructed values for clinical application in practice.

The effect of concomitant gradient fields on MRI with long readout radial‐based trajectories
Magnetic Resonance in Medicine, EarlyView.Abstract Purpose To demonstrate in theory and practice that concomitant gradient fields (CCGF) can produce substantial imaging artifacts in scans utilizing radial‐based trajectories and to provide strategies to mitigate these effects. Theory and Methods A framework was developed to relate concomitant gradient phase to local point‐spread‐function ...

Feasibility study of subject‐specific, brain specific‐absorption‐rate maps retrieved from MRI data
Magnetic Resonance in Medicine, EarlyView.Abstract Introduction Specific absorption rate (SAR) is crucial for monitoring radiofrequency power absorption during MRI. Although local SAR distribution is usually calculated through numerical simulations, they are impractical during exams, limiting real‐time patient‐specific SAR assessment.
