When importing DICOM images, the pixel value is not normalized the CT
scanners HU (Hounsfield Unit) scale. By looking at the DICOM header it's
possible to figure out the scale. But when using the Math pull down and
setting an offset to the pixel scale, the analysis will not allow a
value of less than one.  Anybody know how to set up ImageJ for reading
HU's?
