3D models of anatomical structures can be obtained
by medical imaging techniques (magnetic resonance imaging and
computed tomography). Varying the materials (e.g. polyurethane
and epoxy resin) used in its composition, it is possible to
obtain the radiographic contrast or the equivalence to the
desired tissue. The production of phantoms for specific patient
needs to fill the geometric accuracy requirements as to the
individual’s anatomy, tissue equivalence, so that they can be
usable to perform measures and not be susceptible to the effects
of radiation. The use of 3D printers is a quick way to build
complex objects, so it is justifiable the study of the feasibility
of 3D printing to develop phantoms. Based on this scenario,
the present study aims to validate the computer simulation (for MCNP5) of plates made with 3D printer material to be possible
to study their respective attenuation coefficients.
