This artifact occurs when structures outside of our field of view, but still within the … onstar antenna coverWebbBecause truncation artifacts arise as a fundamental consequence of the Fourier representation of an image, they occur in both the phase- and frequency-encode directions. However, because fewer samples are usually taken in the phase-encode direction (e.g., 128 or 192), the artifact is usually most prominent in the phase-encode direction. ioh riversideWebbTypical artifact correction methods are: improvement of technical equipment, optimization of scanning parameters and pulse sequences and image processing after the scanning procedures.
