A Pattern Designable Hydrogel Vessel Phantom for Ultrasound Imaging

Medical ultrasound (US) imaging has been established as an essential diagnostic tool and US phantoms are fundamental tools to examine the performance of ultrasound imaging. We describe an inexpensive and reusable strategy to establish an ultrasound-imaging hydrogel phantom to satisfy researchers' requirement in this study. The result demonstrated that the transparent and durable ultrasound phantom contained two-vessel lumens, and its ultrasound imaging results were obtained with high-quality. Furthermore, we could observe a clear shape of the present word "PKU" on an ultrasound image by using phase change phantom, indicating that phantom with different internal shapes could be well designed using this strategy. In conclusion, the preparation strategy is feasible for pattern designable hydrogel phantom and can provide valuable prospects for ultrasound imaging.
