Image registration software tools | Nuclear medicine imaging analysis
Image registration is used for aligning two images of the same object into a common coordinate system presenting the fused image. The one image is usually referred as reference and the other as sensed (or referred). Image registration is a spatial transform. The images can be acquired from different angles, at different times, by different or same modalities. A typical example of the use of image registration from different modalities in nuclear medicine is the combination of SPECT and CT images (SPECT/CT) or PET and CT (PET/CT).
