Using inkjet 3D printing to create contrast-enhanced textured physical phantoms for CT

Conference Paper

Anthropomorphic phantoms can serve as anatomically structured tools for assessing clinical computed tomography (CT) imaging systems. The aim of this project is to create highly customized 3D inkjet-printed, contrast-enhanced physical liver phantoms for use in improving CT imaging system analysis. The capability of using voxelized print to create physical phantoms with texture was previously presented by our lab. Building on that technology, we show the feasibility of producing iodine enhanced liver phantoms with varying textures, at resolutions higher than clinical CT using inkjetprinting. We use a desktop inkjet-printer, with custom inks to print these paper phantoms. Sodium bromide (NaBr) ink is used to represent unenhanced tissue, and potassium iodide (KI) represents contrast-enhanced tissue. We have shown the feasibility of using 3D inkjet-printing to create unique, contrast-enhanced liver phantoms for use in CT. In the future, we plan to expand our methods and tools to create tissue-equivalent physical phantoms for other anatomical structures in the abdominal region.
