Title
(EN) PHOTOACOUSTIC IMAGING USING A VERSATILE ACOUSTIC LENS
Abstract
(EN)

To image various soft tissues in the body using pulsed laser optical excitation delivered through a multi-mode optical fiber to create photoacoustic impulses, and then image the generated photoacoustic impulses with an acoustic detector array, a probe includes either a mirror and an acoustic lens or a special acoustic lens of variable focal length and magnification that can operate in a liquid environment that is aberration-corrected to a sufficient degree that high resolution images can be obtained with lateral as well as depth resolution.
