摘要： Provided herein are composite passive layers for ultrasound transducers having acoustic properties that can be easily tailored to the needs of the transducer application using current microfabrication techniques. In an embodiment, a passive layer comprises metal posts embedded in a polymer matrix or other material. The acoustic properties of the passive layer depend on the metal/polymer volume fraction of the passive layer, which can be easily controlled using current microfabrication techniques, e.g., integrated circuit (IC) fabrication techniques. Further, the embedded metal posts provide electrical conduction through the passive layer allowing electrical connections to be made to an active element, e.g., piezoelectric element, of the transducer through the passive layer. Because the embedded metal posts conduct along one line of direction, they can be used to provide separate electrical connections to different active elements in a transducer array through the passive layer.

In another embodiment, the conductive post has an exposed bottom surface allowing electrical connections to be made from the bottom of the transducer. In another embodiment, the transducer comprises an extension substrate adjacent to the acoustic element for protecting the acoustic element from thermal stress when a connection is made to the transducer at high temperatures. In one embodiment, a circuit is integrated on the extension substrate to process signals to or from the acoustic element.

摘要： An intravascular ultrasound imaging system includes a catheter that is insertable into a patient blood vessel. A flushing assembly is in fluid communication with a lumen of the catheter. The flushing assembly flushes air bubbles formed in acoustically-favorable medium in the catheter lumen in response to an event other than a user-initiated flushing prompt. The flushing assembly includes a reservoir containing acoustically-favorable medium for input into the catheter lumen, and a pump coupled to the reservoir. The pump pumps the acoustically-favorable medium from the reservoir to the catheter lumen. A connector is in fluid communication with the reservoir. The connector is coupleable with the catheter lumen. A controller is coupled to the pump. The controller is configured and arranged for controlling operation of the pump.
