What is the atomic number, density and composition of the phantom material?
In general, the majority of our phantoms are made of Lucite ® (Polymethyl Methacrylate). This material is also known as Perspex ® and Plexiglass. Information concerning the atomic number, density and composition of Lucite ® can be found here on the web site of the National Institute of Standards and Technology (NIST). MMA has a density of 0.94 g/cm3. The systematic name is methyl 2-methyl-2-propenoate. Its molecular formula is H2C=C(CH3)COOCH3. Information about polycarbonate can be found here, which is also a URL at NIST.
