The 3D Image Fusion Ramp Cube enables verification of registration for SPECT/CT and PET/CT fusion imaging.
The phantom consists of a 10cm clear urethane cube with three 1mm diameter channels each fitted with standard Luer connections designed to be filled with a radioactive solution. Inserted into each channel is a 0.4mm diameter steel wire. The ramps are set at 23° angles in order to bisect the fused scan slice. When imaged with a CT scanner, the wire creates a high contrast image. When imaged with SPECT or PET the radioactive solution creates a high contrast image. By fusing the two images and comparing the positions of the wires and channels, the registration can be accurately verified and misregistration measured.
