What is a K-space?
The k-space is an extension of the concept of Fourier space well known in MR imaging. The k-space represents the spatial frequency information in two or three dimensions of an object. The k-space is defined by the space covered by the phase and frequency encoding data.
Is K-space the image?
K-space is the Fourier transform of the MR image. Although the k-space "galaxy" and MR image appear quite different, they contain identical information about the scanned object. The two representations may be converted to one another using an advanced mathematical procedure (the Fourier Transform).
