Determination of heavy particle stopping power

摘要

A distribution of heavy particle stopping power is be determined. A distribution of effective atomic number of a three-dimensional space is accessed, and a distribution of an x-ray stopping power of the three-dimensional space is accessed. A conversion is applied to the distribution of the effective atomic number and the distribution of x-ray stopping power. A distribution of the heavy particle stopping power of the three-dimensional space is generated based on the conversion, the heavy particle stopping power being an indication of a depth of penetration for a heavy particle incident on the three-dimensional space.
