Optical Ultrasound Generation and Detection for Intravascular Imaging: A Review

Figure 10

(a–d) Combined ultrasound and photoacoustic images achieved from the all-optical devices using crystal violet and AuNP composites for hybrid transmitters. Coregistered photoacoustic and ultrasound images were obtained from (a‐b) ex vivo swine abdominal tissue and (c‐d) human aorta. Colour-coded photoacoustic images were superimposed on the corresponding ultrasound images. The fatty regions are indicated with black bars. CR, cork ring; HA, human aorta tissue; MB, metal base. (e) Histological images of the imaged human aorta tissue. T, tunica media; A, adventitia. Reproduced with permission from [33], Copyright 2018, John Wiley and Sons.
