Use of solid plastic materials for treatment planning calculations
Accurate phantom reconstruction from a series of CT slices generally requires that
• Phantom dimensions are reproduced correctly
• There is no distortion in the images from image reconstruction
• The slice position and dimension is reproducible
• The slice thickness is correct
• The different materials in the phantom are correctly represented
For faithful simulation of radiation transport in media, the media properties
must be considered:
•Electron Density
•Mass Density
•Chemical composition
