FPGA (Field Programmable Gate Array) based application specific hardware, for real-time Sensitivity Encoding (SENSE) reconstruction, embedded on the receiver coil system may provide reconstruction without transferring the data to the MRI server. This may dramatically decrease the transmission cost of the system and the image reconstruction time. This paper proposes an FPGA implementation of SENSE algorithm using two different sensitivity maps estimation methods (pre-scan and E-maps). The results show that the proposed system consumes only 145.64 μs for SENSE reconstruction (acceleration factor=2), while maintaining the quality of the reconstructed images with good mean SNR (29+ dB) and significantly less artefact power (<9×10^-4) values.
