LSTM-Based RNN Framework to Remove Motion Artifacts in Dynamic Multicontrast MR Images with Registration Model

Figure 1

Motion blurring MR image generated after mixed with k-space sampled data points between frames in scanning sequence. FT is extracted k-space point from individual time instant motion-free frame. A solid line is drawn from k-space sampled and combined to form a mixed with k-space sampled data points. A frame is obtained after passing interpolation added k-space to get motion-blurred image.
