Final answer:
The RF artifact that compensates for the zipper effect in MRI is known as the Zipper artifact. It is corrected through MRI system design that includes RF shielding, filtering, and adjustments.
Step-by-step explanation:
The artifact in question related to RF (Radio Frequency) in the context of magnetic resonance imaging (MRI) is known as the Zipper artifact. This artifact appears as a series of high-intensity lines across the image, resembling the teeth of a zipper, and is caused by interference from unwanted RF signals. The standard method to compensate for the zipper effect is implemented at the level of MRI system design and includes various RF shielding techniques, proper filtering, and the adjustment of frequency encoding gradients to avoid the introduction of stray RF signals during the scanning process.
