Physical Breast Phantom Dedicated for Mammography Studies
This paper presents a simple methodology for creation of anthropomorphic physical breast phantoms dedicated for x-ray breast imaging. The use of physical phantoms in diagnostic radiology is a well-established approach for patient dose estimation, quality control of developed diagnostic systems and development of new breast imaging techniques. An overview of the design process used for the creation of the presented phantom and evaluation approach is given. A combination of materials (Clear resin, Gray resin and PLA) and methods (fused deposition modelling and stereolithography) are used for the manufacturing of the breast phantom. The phantom was subjected to an evaluation aiming at its suitability for studies with digital mammography technique. In particular, the created phantom was evaluated by using two sets of phantom images, taken using 22 kVp and 28 kVp, which are compared with real mammograms. The comparison of the images is based on extracted statistical parameters – namely skewness, kurtosis, fractals, PSA, GLCMContrast and GLCMEnergy.
