Abstract
Contrast agents developed specifically for x-ray diagnostics provide dose-enhanced radiotherapy and radiosurgery. The presence of heavy elements from these contrast agents, even small quantities, leads to a major dose increase in target tissue. When combined with in vivo calibration of the amount of contrast agent, the procedure is quick, accurate, and safe. The technique can also be used in combination with other techniques, such as focused x-rays, to achieve further enhancement of therapeutic ratio. Through optimization of the equipment it is possible to achieve very large ratios of dose in target to dose in healthy tissue up to 10:1.
