Starting Image Fusion

Image Fusion supports Nuclear Medicine, CT, PET, SPECT, and MR data, as well as the fusion of CT or MR with PET or SPECT data.

For Nuclear Medicine, Image Fusion allows you to read all NM images except myocardial perfusion SPECT.

For CT, PET, SPECT, and MR data, Image Fusion allows you to compare up to four studies simultaneously. Each study can contain three series: a CT or MR series, a PET or SPECT AC series, and a PET or SPECT NAC series.

Conditions for fusing PET/CT, SPECT/CT, or MR datasets are as follows:

  • You must load at least one CT or MR dataset in the viewports.
  • The datasets must contain at least two images.
  • The datasets must load at the requested quality.
  • The images must be in transverse orientation.
  • The CT/PET or SPECT datasets must share a common frame of reference.

PET/CT datasets or hybrid PET/MR series that share a common frame of reference are automatically fused into a new study and loaded.

If the CT or MR and PET or SPECT series do not share the same frame of reference, both series launch separately, and Image Fusion displays a warning. You can then use the Fuse Studies option in the Tools menu to fuse them into a new study. If multiple series load, the most current MR or CT series is fused.

To start Image Fusion:

  1. Open one or more of the following combination of studies:

    • PET
    • SPECT
    • CT and PET AC or NAC
    • CT, PET AC, and PET NAC
    • MR
    • MR and CT/PET AC or NAC
    • MR and CT/PET AC/PET NAC
    • CT and SPECT AC or NAC
    • CT, SPECT AC, and SPECT NAC
    • MR and CT/SPECT AC or NAC
    • MR and CT/SPECT AC/SPECT NAC
    • NM dynamic/multiphase dynamic
    • NM static
    • NM whole body
    • Secondary capture image

  2. In InteleViewer, choose the appropriate multimodality sequence protocol to load the series in the viewports or drag the required series into the viewports.

    If the study includes a CT series loaded in the viewports, Image Fusion associates the CT studies with the PET studies with the largest number of transverse slices.

    If the study includes a PET or SPECT AC and PET or SPECT NAC series loaded in the viewports, Image Fusion launches them together.

  3. Click Image Fusion .

    If you start Image Fusion before all the CT/PET or CT/SPECT or MR images stream, a warning appears. If this occurs, click Cancel Launch and start Image Fusion again.
