<div dir="ltr">Hi all,<br><br>I am trying to overlay an dose shade on a CT slice.I am
using vtkDICOMImageReader to read the CT and vtkGDCMImageReader to
display the dose shade.But I am having problem with the coordinates.How
to relate the coordinates? For e.g: I get ImagePositionPatient of CT
image for central slice as [-275,-524,-128.25] and ImagePositionPatient
for dose as [-228.65,-419.25,-122.5] adn their spacings are
[1.074,1.074,3] and [2.52.5.2.5] respectively for CT and Rt dose.<br>
<br>The image looks as in the attached figure.<br><br>Any hint<br><br>Thanks<br><br>Jothy</div>
