摘要: The invention provides a multimodal ultrasound and photoacoustic contrast agent based on polymeric microparticles having a gas core and carrying at least one photoacoustic agent in its shell that stabilizes the gas core, for use in ultrasound and photoacoustic imaging. Such multimodal ultrasound and photoacoustic contrast agent is also suitable as a carrier of drugs and for use in photodynamic therapy, and for tissue imaging ex vivo.

摘要: Photoacoustic imaging systems and methods that allow for the creation of three-dimensional (3D) images of a subject are described herein. The systems include one or more optical fibers attached to an ultrasound transducer. Ultrasonic waves are generated by laser light emitted from the optical fiber(s) and detected by the ultrasound transducer. 3D images are acquired by ultrasound signals from a series of adjacent scan planes or frames that are then stacked together to create 3D volume data.

摘要: A transducer with triangular cross-sectional shaped pillars is described for suppressing lateral modes within a composite, and a method for producing the same. According to one aspect of the present application, a plurality of triangular cross-sectional shaped pillars extends outwardly from a substrate and form an array of pillars. The resulting array of pillars is configured to suppress the lateral modes of the transducer at higher operating frequencies, such as, at or above 15 MHz, at or above 20 MHz, or at or above 30 MHz.

摘要: Systems and methods for producing three-dimensional ultrasound images are disclosed herein. In one embodiment, ultrasound image data are acquired in discrete time increments at one or more positions relative to a subject. The image data is time stamped relative to an offset to a reference point. The image data is synchronized relative to the reference point and combined to form a loop of three dimensional images.

摘要: An imaging system includes a plurality of elongated rails, a scanhead assembly, and a small animal mount assembly. The scanhead assembly is mounted to be moveable in a linear bidirectional manner along a longitudinal axis of the first rail. The small-animal mount assembly is mounted to be moveable in a linear bidirectional manner along a longitudinal axis of the second rail. The second rail is mounted relative to the first rail so the longitudinal axis of the second rail is at an angle to the longitudinal axis of the first rail. The imaging system may also comprise a needle injection assembly that is mounted to be moveable in a linear bi-directional manner along the longitudinal axis of the third rail. The third rail is mounted such that a longitudinal axis of the third rail is substantially coaxial to the longitudinal axis of the first rail.
