Prompt-gamma imaging during ion therapy has proven its ability to control the ion range in real time. The achievable precision is of the order of the millimeter for a single spot in proton pencil beam scanning. Collimated gamma cameras have been developed, that are close to clinical application. The Compton cameras are also under development in various laboratories. Time of flight enables the reduction of the background due to other prompt radiations.
