In vivo freehand OpUS imaging of the common carotid artery. (a) Schematic diagram of the target region for in vivo imaging of the common carotid artery. (b) Conventional piezoelectric ultrasound image of the common carotid of a human volunteer. (c) Freehand OpUS images of the common carotid artery in vivo, with the vessel running parallel to the imaging probe body. The vessel lumen is annotated in (b,c). (d) M-mode imaging of the common carotid artery in vivo, comprising laterally averaged signals, demonstrating the motion of the deeper wall of the artery over time. Examples of carotid artery imaging are shown in supplementary video S3.
