Hello everyone! I faced with such a problem: I parsed SR000001.dcm and extracted the markup coordinates from the Graphic Data. Then, using ReferencedSOPInstanceUID, I found the correct dcm slice and tried to draw the markup on the slice, but it turned out to be about 1.15 times smaller than the original one that I see in OHIF. Please help me figure it out.
Hello,
Not much to contribute, here, but are you sure you’re not conflating coordinates in pixels versus real-world coordinates? (pixels on the left, millimeters on the right?)
You should check the PixelSpacing dicom tag : maybe it’s precisely 1.15, which would be a clue ? (or 0.87, which is the inverse)
Apologies if this sounds stupid, but that’s the first check I would make.

Hello,
In addition to Benjamin’s answer, please note that this question is totally unrelated to Orthanc.
