These commands are used change the intensity scale for viewing the image.
These commands do not change the image data. When the minimum value is
set, then the color pure black is assigned to that image value. Similarly,
when the maximum value is set, the the color pure white is assigned to that
image value.<P>
Changing the intensity scale is useful when examining different image features.
In clinical medicine, the intensity scale is often changed to examine bone
(high value) versus soft-tissue (medium value) features.<P>
<A HREF="ctsim63.html#IDH_DLG_MINMAX"><B>Set</B></A><BR>
This command displays a dialog box that sets the lower
and upper values to display.<P>
<A HREF="ctsim64.html#IDH_DLG_AUTOSCALE"><B>Auto</B></A><BR>
This command displays a dialog box that allows <TT>CTSim</TT> to automatically
make an intensity scale. The parameters that <TT>CTSim</TT> needs to make this
automatic scale are:<P>
<TABLE>
<TR><TD VALIGN=TOP>
<B>Center</B>
</FONT></TD>
<TD VALIGN=TOP>
This sets the center of the intensity scale. Currently,
<TT>CTSim</TT> allows you to use either the mean, mode, or median of the image
as the center of the intensity scale.
</FONT></TD></TR>
<P>
<TR><TD VALIGN=TOP>
<B>Width</B>
</FONT></TD>
<TD VALIGN=TOP>
This sets the half-width of the intensity scale. The half-width
is specified as a multiple of the standard deviation.
</FONT></TD></TR>
</TABLE>
<P>
As an example, if <TT>median</TT> is selected as the center and
<TT>0.5</TT> is selected as the width, the the minimum value will
be <EM>median - 0.5 x standardDeviation</EM>
and the maximum value will be <EM>
median + 0.5 x standardDeviation</EM>.<P>
<A HREF="ctsim65.html#topic43"><B>Full</B></A><BR>
This command resets the intensity scale to the full scale of the image.<P>
