The What Is K-Space? Tutorial
K-space can be a mind-numbing mystery. And then it's not. No, wait …then it is again. This tutorial is designed to give you a practical understanding of what k-space is, what the data within it is, and how that data affects the image, without difficult maths, or even mentioning spatial encoding (shudder)! This first tutorial on k-space is easy going, so sit back and relax. By the time you finish it, you will have a useful understanding of how messing with k-space can have particular effects on the image. This includes the effects of deliberate manipulation of k-space (e.g. partial Fourier) as well as artefacts (e.g. RF noise spikes). Go for it!
