Fusion- The Integration ProblemFusion- The Integration Problem
Results not readily transferable between systems Proprietary or inconsistent implementations Lack of guidance
Results presented on different systems may not appear the same.
Systems must correctly handle issues such as Identifying and retrieving the right datasets Matching data between single-slice and multi-slice
datasets Performing spatial translations Rendering the fused display

Fusion- The Integration SolutionFusion- The Integration Solution
A collection of DICOM objects exists to address the problem.
Their use is constrained and clarified to avoid misinterpretation and promote compatibility.
