3D printed cortical bone mimic-material for medical physics

Abstract Treatment and diagnosis in Nuclear Medicine and Radiotherapy require simulators able to mimic the human body to pre-assess the radiation behavior of new techniques and radiopharmaceuticals. Development of such simulators requires materials to behave similarly to the body tissues and with more real shapes to obtain more reliable results. XCT-A and XCT-B are new 3D printing materials that simulate cortical bone behavior. CT results confirm bone-like attenuation. X-ray fluorescence reveals the preeminent presence of Barium, Calcium, and Sulfur, and Raman spectral lines are similar to ABS material.
