RF System - Video Lesson

Hey, everybody. Welcome to today's lesson on instrumentation in MRI. This lesson focuses on the radio frequency or RF system, including the various components of the RF system, their functions, and their significance in magnetic resonance imaging. The RF system is vital to MRI because without it, there would be no magnetic resonance, thus, no signal to detect. The RF system in an MRI scanner consists of a waveform generator, a digital to analog converter, a frequency synthesizer, an amplifier, a transmit coil, a receive coil, a preamplifier, an analog to digital converter, and a display system. The waveform generator is the first step in the transmit receive chain. As its name suggests, it produces low power
