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.

Value PropositionValue Proposition
Interoperable DICOM encoding for registered/fused data
Consistent and reliable acquisition, storage and presentation of fused data across vendors
Allows separation of workflow steps: Acquisition on “A”; Fusion on “B”; Display on “C”
Wider distribution of results
Separable registration for re-doing if necessary
Can easily request basic interoperable fusion features. E.g. blended display, MPR, side by side display, etc.
Supports PET-CT (primary initial interest) viewing on general radiology PACS displays
Modality independent
Supports general needs in radiation oncology pre-planning
