During data rendering, such characteristics as surface textures, lighting aspects, and reflection properties are calculated. Because of its computational requirements, a desired goal is to perform data rendering on computer resources other than the design workstation. The code is currently being validated against other 3D PIC codes and is being used to simulate high power microwave devices. The demonstrated capability of parallel ITS will be used to better simulate the effects of nuclear explosions, lessening the need for underground tests forbidden by international treaty. This has been achieved on many fronts, including improvements made in diagnostic and therapeutic modalities.
Radiation is a highly effective therapy in many cancers.
These findings reflct not only the trend to better survival with a high quality of life, but also the necessity of the use of radiation in treating breast tumors. Over the last 30 years, the improvement in radiation therapeutic techniques has been significant. Yet results of National Cancer Institute studies indicate that there is much room for improvement in the science of radiation therapy planning. Recently, researchers at UCLA have developed methods of radiation dose calculation which are considered to be the most accurate available. The Monte Carlo methods developed there model the physical interactions between the radiation beam and individual patients.
