Brief
This Master's thesis focuses on the design and testing of a high-speed data transmission system for magnetic resonance imaging (MRI) using FPGA and optical fiber devices, which includes a novel encoding method for MRI echo data and the transmission of both configuration parameters and an analog local oscillator signal.
Summary
This Master's thesis explores a high-speed data transmission system for MRI using FPGA and optical fiber devices to overcome limitations of traditional coaxial cables. The research includes:
- Developing a digital signal transmission circuit using optical fiber.
- Creating an FPGA-based method for transmitting configuration parameters via optical fiber.
- Proposing and validating a new encoding scheme for MRI echo data that reduces data overhead compared to traditional methods.
- Developing a circuit for low-distortion transmission of an analog local oscillator signal over optical fiber. The goal is to improve MRI signal quality and reduce interference by moving data acquisition closer to the signal source in a shielded room and using fiber optic transmission to the spectrometer.
