All the studies shown on the Adjust/Compare page have run through the reslicing process and hence have the same resolution as the Reference study. As a consequence, there is a one-to-one relationship between the pixels in all studies. This allows several tasks to be performed easily:
▪The pixel values in two or three studies can be combined (for instance by adding the RGB colors) to calculate a "fusion" value. All fusion pixels together form a fusion image.
▪Image algebra can be performed with the pixel values, for instance to calculate a pixel-wise difference image.
▪VOIs can be applied to several studies, and the values of the VOI pixels shown in scatter plots (2D or 3D).
▪Reports can be generated and saved as JPG/TIFF, or as a DICOM Secondary Capture object.
If the after automatic matching or initial reslicing is not yet satisfactory, there are two methods to adjust the alignment with the Reference:
▪Manual Matching, or
▪Markers Matching
Note: Images matched manually or with the markers method can be saved with the 
button in the taskbar, or using the CoReg button on the Initialize/Match page.
The different registration modes and processing tasks are described in the following sections.
