Description
3D-printing technologies are increasingly employed across a wide range of applications, including medical imaging. Their current capabilities enable the rapid and cost-effective fabrication of complex geometries, making them well-suited for developing custom imaging phantoms. Recent studies have demonstrated the feasibility of producing image quality test phantoms for planar X-ray imaging using 3D printing [1]. Furthermore, 3D printing is widely used in the creation of anthropomorphic and zoomorphic imaging and dosimetry phantoms that accurately replicate the anatomical shapes and radiological properties of biological tissues [2–3].
A key challenge in this field is the selection of appropriate materials that can accurately simulate the radiation interaction characteristics of various tissues. While standard plastic filaments are generally adequate for mimicking soft tissues, replicating bone tissue properties remains more complex. This study evaluates the suitability of several commercially available, admixed plastic filaments for simulating bone tissue. The assessment was based on Hounsfield units and electron density values derived from CT scans of 3D-printed samples with varying infill densities. Imaging was performed using a Philips Brilliance 64 clinical CT scanner.
