RF Reception (Rx) chain: simulate signals from images and view reconstruction after demodulation and sampling

caller_script_Rx.py

run_Rx_sim(Rxinfo)

Runs MR receive chain simulation

Receive chain is simulated by modulating k-space from an axial, coronal, or sagittal brain image, and then demodulating using selected demod. frequency and sampling at selected down-sampling factor (dsf).

Parameters

Rxinfo (dict) –

Dictionary of parameters used to run Rx simulation

{‘deltaf’: demod_frequency, ‘image-or’: image_orientation, ‘DSF’: downsampling_factor}

Returns

• signals_plot_filename (str) – File name for plot of time-domain signals (.png format)

• recon_plot_filename (str) – File name for image reconstructed from demodulated & sampled signals (.png format)

• im_path (str) – Path of image used for generating artificial k-space
