Philips Healthcare Develops Smart Digital RF Power Subsystem for MRI Systems

Pages 2 Pages

Magnetic resonance imaging (MRI) systems apply powerful radio frequency (RF) and strong magnetic fields to systematically align the magnetic moment of protons in human tissue. For an MRI system to pro- duce good quality images, the timing and linearity of the RF power subsystem must be precisely controlled. With the peak power of the RF power amplifiers approaching 40 kW, keeping the signal phase accurate to within a few picoseconds is a
