- W2891998940 abstract "3D printing is an exciting tool in patient centered precision medicine. 3D printing tools have been demonstrated to be useful in medical education and for surgical planning. However, 3D printing is not commonplace in medical imaging (MI) departments. There are no standardized metrics for assessing the performance of 3D printed models in a MI department and the framework(s) for a multidisciplinary approach is yet to be clearly defined. A successful 3D printing program in MI requires the close collaboration of a multi-disciplinary team that includes the radiologist, technologist, medical physicist and the biomedical engineer. Technologists are uniquely positioned to take a leading role in helping to build a successful 3D printing lab within the medical imaging department. This case study successfully demonstrates the key role that technologists can play within a multi-disciplinary collaboration in designing and constructing an abdominal phantom with realistic radiological properties utilizing 3D printing methods. An abdominal model was needed to evaluate digital tomosynthesis, without having to irradiate patients. Two technologists in collaboration with a radiologist and a biomedical engineer designed and constructed a low cost, 3D printed, tissue realistic modular abdominal phantom comprised of a liver, colon, pancreas, kidneys and spleen with surrounding fatty tissues. Technologists with experience in anatomic segmentation, 3D software modelling and printing used a combination of patient specific CT scan data and publicly available scan data to 3D print abdominal organs using fused deposition modeling. The resulting phantom demonstrated a qualitative and quantitative structural match in terms of accuracy in tissue CT attenuation (HU values). The HU values for the organs were; liver 38+/-15, spleen 26+/-12, kidney cortex 52.5+/-11, kidney calyces 35+/-10, pancreas 54.5+/-13, muscle 54.5+/-13, pelvic bone 575+/-22. Case study demonstrated successful completion of a complex 3D printing project by a multi-disciplinary team led by technologists." @default.
