What is the additional cost of the CT section of the scanner?
The additional cost of the CT section (see Figure 3) includes only the cost of the electron beam generator, the focus and deflection coils, the tungsten target rings, and the vacuum pump system. The other components such as the detectors, photomultipliers and the electronics are the same as the ones used for PET. For the additional components for the CT scanner, the cost has been generously estimated $1 million. The CT + PET will make a 3D-CBS device with a cost of about $6 million.
