WebDec 23, 2024 · POCS-CycleGAN was validated using MR data in a single coil. Extending it to multiple coils is straightforward by concatenating the data from all the coils during model training and image reconstruction. In other words, data from different coils will be treated as separate training samples and input. WebWe apply enhanced POCS to high-resolution multi-echo FLASH and 3D-EPI functional MRI time-series data. Results: Reconstruction errors and their bias dramatically reduce compared with existing methods, without leading to temporal blurring in time-series acquisitions. This allows for higher PF acceleration factors at virtually no cost. is scd a disability
