Data Clipping Artifact

Clipping artifact in MRI occurs when the received signal from the object being imaged exceeds the dynamic range of the MRI scanner. This can result in the signal being truncated or “clipped” at the maximum or minimum value, leading to loss of image information and distortion of the image.

The appearance of clipping artifact in an MRI image can vary, depending on the severity and location of the clipping. In some cases, the affected area may appear as a bright or dark band, or as a “step” at the point of clipping.

Data Clipping artifact MRI

Here are some strategies to minimize or avoid Data Clipping artifact :

One method to address the clipping artifact is to adjust the receiver gain or other scanner settings to increase the dynamic range of the scanner. By increasing the dynamic range, the scanner becomes capable of capturing a wider range of signal intensities without saturating or truncating the data. This adjustment helps prevent the loss of information and reduces the occurrence of clipping artifacts in the reconstructed images.
