Limited number of targeting angles
with conventional devices
Depending upon the exact location of a lung cancer, it may be difficult to deliver the necessary high dose of radiation to that cancer using “conventional” radiation techniques, without also delivering a substantial dose to the normal tissue traversed by any given radiation beam path, sometimes even affecting normal tissue that resides far away from the target lesion. |
