Abstract

While tissue-mimicking phantoms have been useful in the validation of ultrasonic equipment and image processing techniques, they are often restricted to simple vascular geometries due to limitations in fabrication techniques. To address this need, a novel technique has been employed to fabricate 3D-printed photo-curable poly(ethylene glycol) (PEG) hydrogel constructs containing complex, small-scale (e.g., 100s of μm in diameter) vascular channels that can be imaged with ultrasound. In this study, we use color Doppler ultrasound to obtain 3D velocity vector fields through vascular geometries within hydrogel phantoms and compare these results to optical flow assessment and numerical modeling results.
