Title of Research: Development of a dedicated brain phantom for Hybrid PET/MRI acquisition

Research Purpose: The project aims to investigate a new series of 3-D printable rubber-elastomeric polymers on behalf of their suitability to serve as tissue mimicking materials (TMMs) for the development of novel phantoms for hybrid PET/MRI.

Main outputs/results: The initial results demonstrate that these materials have a close dielectric, radiological and structural properties compared to the properties of tissues and organs of the human body and they hold great promise for designing novel phantoms for hybrid imaging, such as Hybrid PET/MRI (Biograph mMR)
Main Impact: This study demonstrate that these filaments with their unique properties will be good candidates for the construction of phantoms (e.g. for mimicking brain tissues) for hybrid PET/MRI using a low cost 3D printing layer by layer additive manufacturing method. Such novel multi-modal phantoms could potentially be used as new standard for development and evaluation of PET/MRI methods (e.g. regarding attenuation and motion correction, image reconstruction and general image quality assessment).
Moreover, this study might serve as a reference or guideline for scientists and researchers on how to handle these new experimental 3D printable filaments and how to utilize these materials in medical field applications, especially the applications that required flexible 3-D printed objects.
