Physical test phantoms are valuable tools in the assessment of novel breast imaging techniques. It is important that they reproduce the breast characteristics as close as possible. This paper presents a methodology for the creation of a software breast phantom that produces a structured background in both two dimensional mammography and breast tomosynthesis. The phantom is composed of spherical objects different in size placed in a semi-cylindrical container. This software breast phantom is used to further improve the existing physical phantom in terms of use of other more appropriate materials or a structure presentation different than the use of spheres. For this purpose, a simulation platform that allows the creation of software versions of the physical phantom with parameters (sizes, shapes, materials) easily adjusted by the user, was developed. Besides the research aspects of the computational phantom, the software tool has turned out to be very useful application for the training of Medical Physics Experts. Specifically, the tool has been used in the training of the participants of module 5 “The use of physical and virtual anthropomorphic phantoms for image quality and patient dose optimization” from the EUTEMPE-RX project that is related to the qualification of Medical Physics Experts in Diagnostic and Interventional Radiology.
