An adapter for a container that provides an integrated photoacoustic microscopy system that is capable of real time imaging of samples within the container. The adapter allows a researcher or investigator to evaluate a sample using the photoacoustic effect, with or without a microscope. The adapter comprises a support portion, a planar portion, and a tube. The support portion includes a channel formed therein, the channel including a first surface, a second surface opposite the first surface, and an intermediate surface positioned between the first surface and the second surface, the channel configured to receive the rim of the container such that the intermediate surface of the channel is positioned adjacent a top surface of the rim and the first surface and the second surface extend along opposite sides of the sidewall. The planar portion is coupled to the support portion and extends across the opening of the container. The tube is coupled to and extends from the planar portion, the tube defines a bore having an axis, the axis being oriented at an angle relative to the planar portion, the bore configured to receive a photoacoustic transducer for real time imaging of a sample within the container.

A photoacoustic and optical microscopy combiner. The combiner is configured to support a transducer defining an axis. The combiner includes a body including a base and an opening extending through the base, and a glass member at least partially positioned within the opening. The glass member includes a surface positioned at an angle relative to the base and the axis of the transducer. A sample slide is supported on the body and at least partially over the opening. The sample slide is positioned such that a sample on the sample slide is configured to receive light from a laser and redirect the light to an ultrasound transducer to generate a real-time image of a sample.

Methods and systems for image-based guidance in deep-brain stimulation. An endoscope system includes a waveguide tube, a right-angle prism, a light source, and a photoacoustic transducer. Light from the light source propagates along the length of the waveguide tube via internal reflection within the wall. The right-angle prism is positioned to redirect light emitted at a distal end of the waveguide tube in a direction perpendicular to the length of the waveguide tube. Light emitted in the perpendicular direction causes soundwaves to be generated by the surrounding tissue via photoacoustic effect. Those soundwaves are then conducted through the interior channel of the waveguide tube from the distal end of the waveguide tube to a proximal end of the waveguide tube where the soundwaves are detected by the photoacoustic transducer, which is acoustically coupled to the interior channel of the waveguide tube at the proximal end of the waveguide tube.

Photoacoustic targeting systems for intracellular recording. In one embodiment, the photoacoustic targeting system includes a light source, a micropipette electrode, an acoustic transducer, and a controller. The light source is configured to emit pulsed light. The micropipette electrode is configured to deliver the pulsed light to a target cell. The acoustic transducer is configured to receive photoacoustic signals generated due to optical absorption of light energy by the target cell. The controller is configured to determine a position of the micropipette electrode relative to the target cell based on the photoacoustic signals.

A device comprises a miniature transducer having an altered backing geometry that can be placed within different casing sizes of an imaging probe device. The backing geometry extends along a longitudinal axis of the imaging probe and provides an angle (e.g., 45-degree angle) configured to reflect ultrasound and/or light waves/signals in a direction perpendicular to the longitudinal axis of the imaging probe. This design is configured to enable ultrasound and/or light waves/signals to be redirected and dampened within the transducer to preserve a suitable signal to noise ratio while minimizing the required depth of the backing.
