Obviously, the stego image with weight adjusting operation owns better perceptive quality than the other one since the operation can reduce the possibility of forming black spots.
They move only as the player moves the main character, mirror images with weight and substance.
For each repetition, one image with no diffusion weighting (b0; b-value = 0 s/mm) was acquired.
DTI images were obtained using a single-shot echo-planar imaging sequence in 50 axial planes with 15 noncollinear diffusion sensitization gradients (b = 1,000 s/mm), and a reference image with no diffusion weighting (b0 image), using array spatial sensitivity encoding to reduce susceptibility and eddy-current artifacts [Reese et al., 2003].
At each slice location, four images were acquired with no diffusion gradients applied, together with 32 diffusion-weighted images (diffusion weighting b-value = 1300 s/mm).
If you get up in the morning and plan to make a portrait, the path is clear; but if you get up in the morning and you want to make an image with metaphorical weight, the path isn't so clear.
One of the possible limitations associated with the use of HYPR (with settings illustrated in this study) when compared to the implementation by Reilhac et al. is that HYPR with a single composite image (weighting factors equal for all frames) assumes that the spatial distribution of activity does not change across different time frames.
Five additional images with minimal diffusion weighting (b = 33 sec/mm2) were also acquired (B0 images).
Additionally, three images with no diffusion weighting (b value = 0 s/mm) (b = 0 images), were acquired using a spin-echo EPI sequence (TR = 10293 ms, TE = 55 ms, FOV = 22.4 cm, 2 × 2 × 2 mm voxels, 60 slices).
Five images with minimal diffusion weighting (b = 0 s/mm) and 30 high b-value images (b = 1918 s/mm, G=35 G/ c m) were acquired according to the Jones30 scheme [ 23- 25].
The following parameters were used: 73 contiguous slices, slice thickness = 2 mm, field of view 224 mm, matrix 128 × 128 (voxel size = 1.75 × 1.75 × 2 mm), b value = 1000 and four images with no diffusion weighting (b = 0 s/mm).
