Abstract:
1. An electron paramagnetic resonance imaging system, comprising: means for continuously irradiating a sample with RF irradiation; means for imposing on the sample a sinusoidally varying magnetic field along with rotating gradients for spatial encoding; means for directly detecting signal data from the sample, without using field modulation, while irradiating the sample with RF radiation continuously, said means for directly detecting having means for sweeping the sinusoidally varying magnetic field; a digital gradients and sweep controller operationally coupled with said means for imposing on the sample a sinusoidally varying magnetic field along with rotating gradients for spatial encoding, said means for directly detecting signal data from the sample, and said means for processing the signal data, said digital gradients and sweep controller configured to automatically maintain the relative speeds for the sweep current and the gradient currents and adjust the timing for detecting signal data; and means for processing the signal data, using means including a digital signal processor.
