Radioactive beams give a real-time view of cancer treatment in mice
This is the first successful treatment of tumors using radioactive ion beams
Scientists used a beam of radioactive carbon-11 ions to treat a tumor (region circled in red) in a mouse. Red colors indicate where most of the ions stopped and decayed, as measured by PET scan. The ion beam comes from the left, and most particles stop before they hit the mouse’s spine (imaged with a CT scan).
