Construction of 1-year-old Child Voxel Phantom Based on CT Image of Physical Phantom

The construction of 1-year-old child voxel phantom （CPP01） based on the physical phantom CT image of Model 704-D and Chinese reference adult male phantom （CRAM） was introduced in this paper, including the construction of OCP01 （original computational phantom, which is a voxel phantom based on the CT image without optimization）, the construction and optimization of CPP01. The mass of individual organ of CPP01 is in accordance with that of GBZ/T 200.2—2007 with the relative error less than 5%, and CPP01 matches the physical phantom of Model 704-D in organ position.
