Then what happen to the image if we change the sampling scheme compared to this case?
If this case samples images like that and
this one samples much bigger range for the k space.
But number of points are fixed, but what will happen to the template image?
And if samples with smaller field of view, okay?
Smaller field of view, but number of templates are the same,
so that increase space, that increases spacial resolution, okay?
Because field of view gets reduced,
the reason is field of view of the images
corresponds to the one sample size on the k-space.
Because of that, this field of view gets small
because this one sample size gets bigger by changing sampling scheme like that.
So this step size gets bigger which means this
imaging field of view gets smaller because they have inverse relationship, okay?
But number of samples aren't a thing, because of that sampling,
the resolution has increased compared to the previous case, okay?
The same thing is also true if we maintain the time for
sampling or increase gradient strength twice.
Compared to the previous one, compared to this regional case.
In the previous slides, time was twice longer, and
that also increase the area on the case base.
The same thing is true, if we increase gradient strength, but
the time is maintain.
But they will give the same region.
So case based, maximum range match increased.
So in this case, again, the sample, case-based sampling period,
this delta Kx becomes bigger, that means field of view gets small.
