Figure 6.
Sample raw data from UTE and ZTE acquisitions in the (a) brain, (b) ankle, and (c) knee. The k-space data is normalized to pixel values, such that the maximum extent in k-space is ±0.5 1/pixel, and only up to a radius of 0.1 is shown. The ZTE data includes the low-resolution projection data required to fill in the center of k-space for the WASPI technique up to a radius of k ≈ 0.01 1/pixel.
