Radiofrequency generator and programmer of pulse sequences for PMR relaxometer
Described the generator of resonance radiofrequency with the step of change 50 kHz in the range 520 MHz and pulse programmer of the pulse sequences for relaxometer of proton magnetic resonance (PMR). Using algorithm of direct digital synthesis (DSP), the RF generator has the ability to produce RF s...

| description | Described the generator of resonance radiofrequency with the step of change 50 kHz in the range 520 MHz and pulse programmer of the pulse sequences for relaxometer of proton magnetic resonance (PMR). Using algorithm of direct digital synthesis (DSP), the RF generator has the ability to produce RF signal with a short switching time and high resolution in frequency and phase. To facilitate the generation of RF pulses, used the pulse programmer implemented in the FPGA directed by the auxiliary controller DSP to generate RF pulses with required sequences and parameters. Realized the testing of the generato r by method of computer modelling in the program Quartus II 12.1 and was shown the opportunities of synthesis of RF-pulses sequences with the phases 0, π/2, π, 3π/2 with resonance frequency tuning. |
