<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

starting at the top left hand corner of the image then rastered right and down
with the last pixel in the sequence being the bottom right hand pixel. The
origin of the image is the top left corner of the image. So far this is pretty
much the same as axial </span></font><font size=2 color=navy face=Arial><span

Positive X left to right, positive Y bottom to top - i.e. the image data
is sent with decreasing Y values. So if I use the ITK stuff and set the origin
of the image according to the origin which is specified in the original file
then the image comes out mirrored vertically about the horizontal line through
the specified origin. </span></font></p>

an image of width, height of 512,512 and origin -256,256 and pixel size 1mm is
actually centred on the origin. </span></font></p>
