Abstract

The hybrid nature of optoacoustic imaging might impose limitations on concurrent placement of optical and ultrasonic detection components, especially in high resolution microscopic applications that require dense arrangements and miniaturization of components. This hinders optimal deployment of the optical excitation and ultrasonic detection paths, leading to reduction of imaging speed and spatial resolution performance. We suggest a compact coaxial design for optoacoustic microscopy that allows optimizing both the light illumination and ultrasonic detection parameters of the imaging system. System performance is showcased in phantoms and in vivo imaging of microvasculature, achieving real time operation in two dimensions and penetration of 6 mm into optically dense human tissues.

Above the dot-dash line shows an imaging depth of 3.2 mm; (b) A picture of the imaged palm with black frame indicating the area that was used for later on 3D optoacoustic imaging. Abbreviations: sc - stratum corneum; e - epidermis; d - dermis; sp - subpapillary plexus; pp - princeps pollicis; cp - cutaneous plexus; pb - pollicis brevis. Application of skin removal algorithm for deep tissue contrast enhancement is shown in (c)-(f). MAP optoacoustic image of the entire imaged area without removing signals from the skin is shown in (c). Panels (d)-(f) show the corresponding MAP images after removing signals up to a depths of 330 µm, 420 µm, and 540 µm, respectively. Scale bars: 1mm.
