Abstract
An apparatus and method for the treatment of a patient having a tumor is disclosed. An X-ray generating source is positionable at a location in close proximity to the tumor. The X-ray generating source is operable at a voltage level in the range of approximately 10-60 KeV, thereby enhancing absorption of the generated X-rays by the tumor and minimizing the side effects of radiation therapy on the patient's normal tissue.
