Figure 10

A mockup of what the screen might look like in a CancerZap! video game. The player shoots x-ray photons at a scene that is rotating, with one object (the Martian eye [152]) in this case representing the “bad guy” tumor. The gun’s lateral motion would correspond to a fan beam. As in CT Brush, the objects would only become visible as they were shot at, accumulating x-ray dose. In the plane, the ornate figures would be represented by simpler “footprints”, such as triangles and circles, shown here beneath them.
