Wall-less Flow Phantoms with 3D printed Soluble Filament for Ultrasonic Experiments

Abstract Tissue-mimicking materials (TMMs) typically used for ultrasound phantoms include gelatin, agarose and polyvinyl alcohol (PVA). These have shown sufficient similarity in parameters compared to human tissue. Despite their extensive use years generate phantoms, no simple easily reproducible way complex, wall-less flow has been introduced. Commercially available are limited geometries that do not reflect the complex blood humans. Flow with presented scientific publications either walls between TMMs channel, one material, or complicated produce. In this contribution, we present a method using 3D printing soluble filament allows reliable consistent production of typical without any walls.
