Thank you very much.
It is an image of a brain slice. The data range is from 0 to 1000. The slice
is located in the middle of the image. The difference between the two is
amplified at the boundaries which are of high intensity. You can find all
By the way, we accept Turkish Kurush only [0.02 Turkish Liras]. :))
Many thanks.
