Limitations with Other Radiotherapy Approaches
Limited number of targeting angles with conventional devices
There is a limited number of radiation beam paths available to a standard linear accelerator, making it difficult to deliver an extremely high dose of radiation to a target lesion, without also delivering a substantial dose to the normal tissue traversed by any given beam path. In some cases, even normal tissue that resides a significant distance from the target lesion may receive a large dose of radiation because of this fundamental device limitation.
