▣ Abstract :

 High-resolution

volumetric optical imaging modalities, such as confocalmicroscopy, two-photon microscopy, and optical coherence tomography, have

become increasing important in biomedical imaging fields. However, due to

strong light scattering, the penetration depths of these imaging modalities are

limited to the optical transport mean free path (~1 mm) in biological tissues. Photoacousticimaging, an emerging hybrid modality that can provide strong endogenous and

exogenous optical absorption contrasts with high ultrasonic spatial resolution,

has overcome the fundamental depth limitation while keeping the spatial

resolution. The image resolution, as well as the maximum imaging depth, is

scalable with ultrasonic frequency within the reach of diffuse photons. In

biological tissues the imaging depth can be up to a few centimeters deep.

In

this presentation, the following topics of photoacousticimaging will be discussed; (1) multi-scale photoacousticimaging systems, (2) morphological, functional, and molecular photoacousticimaging, (3) potential clinical applications, and (4) contrast agents for photoacousticimaging.
