- A methodology for accuracy evaluation of 3D-printed anthropomorphic phantoms was developed. The 3D-printed vessel phantom was a robust representation of the design model and can be used to evaluate CT imaging protocols and reconstruction methods, as its actual morphometry has been characterized.
- Micro-CT imaging allowed to generate an accurate representation of the printed model, which can be used as the ground truth to compare against CT images of the same phantom obtained with different reconstruction algorithms or systems [8].
- The local attenuation properties of the lung vessels and its comparison to commercial lung phantoms and patient data will be investigated in the future. The potential variability of CT attenuation and HU values of 3D-printed materials for different CT manufacturers will also be addressed.
