Sentence examples for for odd time points from inspiring English sources
To this end, we fill the upper half of k- space completely for odd time points in a cardiac cycle.
The results for a sample even time point, point 18, are shown in Figure 7. Second, we use 62.5% of upper mask for odd time points and the extracted mask for even ones and apply our proposed iterative, Lustig's nonlinear conjugate gradient [7], and k-t FOCUSS method [14] to reconstruct images for all time points.
(a) 67.5% mask used for odd time points, (b) extracted mask, 37.5%, used for even time points, (c) a test mask, 37.5%, including center lines and 1/6 of the other lines selected regularly, (d) regular mask, 50%, (e) random mask, 50%, (f) normal (conventional) mask, 50%, along PE direction.
Therefore, the number of heart bits (acquisition time) required for sampling of k-spaces of odd time points reduces.
In the above steps, we gather and use k- space of odd time points to reconstruct the corresponding images and determine sampling pattern of even time points.
In this article, we present a two-step approach to increase the acquisition speed of the cardiac cine MRI by a factor of 2. First, we sample the upper half of k-space lines for the odd time points of the cardiac cycle.
In this article, we present a two-step approach to increase the acquisition speed of the cardiac cine MRI by a factor of 2. First, we sample the upper half of k-space lines, along PE direction, for the odd time points of the cardiac cycle and reconstruct the related images by iterative thresholding.
However, it should be noted that when we do not fill k-space for even time points, we use the time to acquire more k-space data of the odd time points.
Optimal data acquisition at the even time points is learned from the data acquired at the odd time points.
The vertical axis refers to eight coil channels and the horizontal one shows odd time points.
We divide the data acquisition process into two steps: data gathering for odd and even time points of the cardiac cycle.
