A common study in Nuclear Medicine is a PET-CT or a SPECT-CT study. The PET (Positron Emission Tomography) or SPECT (Single Photon Emission Computed Tomography) maps the area of radioactive absorption, and the CT (Computed Tomography) shows the anatomy of the body. These 2 images are overlaid as a fusion image showing the radioactive uptake on the background of the anatomy.
Sometimes MRI (Magnetic Resonance Imaging) is used in addition to the CT as another way to look at the anatomical structure. The MRI can also be fused with the radioactive uptake.
This program uses DICOM data already loaded into the Fiji viewer.
The opening dialog allows you to choose which series you wish to use.
1) Most commonly you will have both PET (or SPECT) together with CT (and maybe MRI) where the two datasets are to be fused. You choose at least 2 datasets and fusion will be available.
2) Sometimes there are cases where there is only PET or SPECT or CT.
With only one dataset, fusion is impossible but you can still see the
data in 3 orthogonal views.
