Abstract:

Aim: 3 Dimensional (3D) printing technology is frequently used in research and educational materials as organ printing in health studies. 3D phantoms offer practical approaches to testing and evaluating imaging techniques and reviewing measurements made on the device. In the study, a special interior design was considered, which adds uniqueness to our study, together with the design of the lung surface anatomy of the phantom, and enables the radionuclide to be transferred to the organ model safely and easily and to obtain images. Method: The reason why the lung interior design is made in this form is that the situations where there is radionuclide contact with the organ can be visualized by means of a phantom and necessary measurements can be made. The 3D anatomical lung phantom was printed in the designed shape and dimensions at appropriate Hounsfield Unit (HU) values, and the internal structure of the Phantom was imaged with medical imaging devices. Results: In the phantom, the lung's inner cavities and outer parenchyma tissue structure were visualized similarly to the natural lung structure in Computed Tomography (CT) images. Conclusion: For use in research and education, a single Photon Emission Computed Tomography (SPECT), Positron Emission Tomography (PET), Magnetic Resonance Imaging (MRI) and CT compatible anatomical lung phantom was designed, 3D printed and necessary radiological images were performed. As a result, the 3D lung phantom produced will be used continuously as educational and research material.
