Chebyshev series for designing rf pulses employing an optimal control approach
(2004)
Magnetic resonance imaging (MRI) provides bidimensional images with high definition and selectivity. Selective excitations are achieved applying a gradient and a radio frequency (RF) pulse simultaneously. They are modeled ...
Baseband model for uniformly sampled RF-PWM
(Institute of Electrical and Electronics Engineers, 2020-03-12)
A baseband model for a polar RF modulator based on uniform sampling (US) pulse width modulation (PWM) is presented. RF-PWM allows to encode a complex baseband signal (amplitude and phase) into the pulse width and pulse ...
