Figure 1. Intravascular multispectral optoacoustic tomography of gold nanoparticle-bearing macrophages in rabbit aorta.

Figure 1

(A) Intravascular ultrasound image and (B) optoacoustic image acquired at 700 nm of an atherosclerotic rabbit aorta injected with gold nanoparticle-bearing macrophages. The arrows indicate the locations where injection was performed. (C) The normalized spectral optoacoustic response obtained in a small section on the aorta, where injection was performed. (D) Multispectral optoacoustic tomography image corresponding to the recovered spectrum overlaid onto the intravascular ultrasound image revealing the injected regions.
