Final answer:
The outer portion of kspace contains data that has low resolution and represents low frequency information. This is because in k-space, the center corresponds to low spatial frequencies and the outer portion corresponds to high spatial frequencies.
Step-by-step explanation:
The outer portion of kspace contains data that has low resolution and represents low frequency information. This is because in k-space, the center corresponds to low spatial frequencies and the outer portion corresponds to high spatial frequencies.
For example, in magnetic resonance imaging (MRI), the outer portion of k-space contains high frequency information that represents fine details in the image, while the center of k-space contains low frequency information that represents the overall structure of the image. By acquiring data from the outer portion of k-space, it is possible to enhance the spatial resolution and capture more detailed information in the image.
