A new theoretical Lorentzian Apodization function: A Simulations based Comparison with traditional Apodization functions
Dalton H Bermudez
Standard apodization methods suppress side lobes but increase FWHM, reducing lateral resolution. Grating lobes can interfere with the main lobe, introducing artifacts in ultrasound…

Assessment of 7T task fMRI value over 3T task fMRI
Dalton H Bermudez
Ultra-high field 7T fMRI offers notable advantages over 3T fMRI, including higher signal-to-noise and contrast-to-noise ratios, enabling finer spatial and temporal resolution. This…
