    摘要: Imaging devices, systems, and methods are provided. Some embodiments of the present disclosure are particularly directed to imaging a region of interest in tissue with photoacoustic and ultrasound modalities. In some embodiments, a medical sensing system includes one or more optical emitters and a measurement apparatus configured to be placed within a vascular pathway. The measurement apparatus may be configured to receive sound waves created by the interaction between emitted optical pulses and tissue, and transmit and receive ultrasound signals. The medical sensing system may also include a processing engine operable to produce images of the region of interest and a display configured to visually display the image of the region of interest.

    摘要: Intraluminal ultrasound devices, systems and methods are provided. In one embodiment, an intraluminal ultrasound device includes a flexible elongate member configured to be positioned within a body lumen of a patient, the flexible elongate member including a distal portion and a longitudinal axis; and a transducer array disposed at the distal portion of the flexible elongate member and circumferentially positioned around the longitudinal axis of the flexible elongate member. The transducer array includes a plurality of micromachined ultrasound transducers (MUTs). In addition, the transducer array is configured to obtain ultrasound imaging data of the body lumen in response to a first electrical signal, and apply an ultrasound therapy within the body lumen in response to a second electrical signal.
