Computational ultrasound imaging (cUSi) provides an economical solution for 3D ultrasonography by integrating an aberration mask on a transducer with few large-pitch elements. We have developed a custom large-footprint transducer with a detachable mask to explore such a cUSi approach for the Carotid Artery (CA). B-mode and flow reconstruction assessment results in phantom studies showed improvements in PSF (from 2.2±1.1 to 1.1±0.1 mm) and CR(Inc1: 9 vs. 5.1 dB, Inc2: 3.7 vs. 0.8 dB). PDI of flow was successfully visualized. These results confirm the potential of our 3D cUSi for CA with a very low number of elements.
