MedicalViewerFusion Class

Summary

A class that contains the fused image along with properties that handle the fusion process.

Syntax

C++

public class MedicalViewerFusion

Public Class MedicalViewerFusion

public ref class MedicalViewerFusion

Remarks

This class is used with the MedicalViewerSubCell.Fusion property.
Fusion is a process used to display multiple, overlapped images at the same time, each having a degree of transparency. Fusion can be used to blend many different modalities such as CT/MR, CT/MR/PET, CT/NM, CT/US, CT/PET...etc.
For example, soft tissue information from a PET scan can be combined with a CT scan, creating an anatomical context for the soft tissue information. As a result, diagnosis and treatment of ailments are improved. For more information, refer to MedicalViewerFusion.

Head and Neck CT/PET Data Set

1. CT Scan Image	2. PET Image	3. CT/PET Fused Image
