DICOM Glossary
DICOM glossary
The tutorials use a fair amount of DICOM vocabulary, and explaining each term where it first appears would make them unreadable. This section answers the question directly instead: what a term means, when it is used, and what to watch out for. Each entry ends with a link to the page that shows how to work with it in Weasis.
