Abstract
Ultrasound phantoms are traditionally made by casting. However, making models by casting will not provide the geometric complexity demanded from real-life biological features, especially when internal structures are present. Gelatin, with its acoustic properties intrinsic for mimicking tissue, is regarded as the ideal material for producing phantoms for ultrasound training. We propose a low-cost 3D printer for producing gelatin phantoms. The design is tested and assessed. Based on the findings, the main recommendations for improving the fabrication process is presented and discussed.
