摘要：
The invention relates to a magnetic resonance imaging system for acquiring magnetic resonance data from a subject within an imaging volume. The magnetic resonance imaging system comprises a transmitter for generating radio-frequency pulses (708) for exciting atomic nuclei within the imaging volume using a radio-frequency antenna. The transmitter has a fixed output amplitude and a modulated output. The transmitter is configured to generate the radio-frequency pulses by switching radio-frequency emissions at the fixed output amplitude on and off. The transmitter is further configured to generate the radio-frequency pulses by controlling the modulated output. The magnetic resonance imaging system further comprises a receiver for receiving radio-frequency emissions from the excited atomic nuclei using the radio-frequency antenna.
