The reason that I thought the value was large is that it appeared to be much<br>
brighter than other pixels inside the volume. and it turned out to be the<br>
problem of indirectly set window/ level because most of the scalar value of<br>
the pixels inside the volume is much smaller than 0. Again, thanks for your<br>
reply~<br>
