At today's DICOM WG22 (DICOM in Dentistry) meeting held at the Radiology Society of North America at McCormick, the ADA SCDI told us that the ADA has funds to hire a consultant for the technical DICOM aspects of the visible light project dealing with images and templates.
A Structured display is a view of various images at once. The intent of this standard is to allow for various entities to share a set of images, and be able to all seem laid out the same way. An application could be, for example, the ABO board exams: the student could submit the images in a specific DICOM template, which he or she could generate with any DICOM compatible application that would support such functionality, which, hopefully at some point, most orthodontic software package would support.
